Mishka is on a long road trip, and she averages 75 mph for 2 hours while she's driving on the highway. While she's driving on side roads for 1 hour, she only averages 45 mph. What is the total distance that she covers on her road trip?
A.
120 miles
B.
195 miles
C.
240 miles
D.
75 miles

Answers

Answer 1

If she goes 75 mph for 2 hours, that's 150 miles altogether. 45 mph for 1 hour is 45 miles, so 150 + 45 is 195 miles.

Answer 2

The total distance that Mishka covers on her road trip is 195 miles.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

To calculate the total distance covered on the road trip

we need to add the distances traveled on the highway and side roads.

Distance on the highway = speed × time

= 75 mph × 2 hours

= 150 miles

Distance on side roads = speed × time

= 45 mph × 1 hour

= 45 miles

Total distance covered = Distance on the highway + Distance on side roads = 150 miles + 45 miles

= 195 miles

Therefore, the total distance that Mishka covers on her road trip is 195 miles.

What is the slope of the line that passes through the points (3, 6)(3,6) and (1, 2) ?(1,2)

Answers

Answer:

-2

Step-by-step explanation:

Using the slope theorem:

[tex]m=\frac{y_{1}-y_{0}}{x_{1}-x_{0}}[/tex]

[tex]\frac{6-2}{1-3} = \frac{4}{-2} =-2[/tex]

The slope of a line passing through two points can be calculated using a formula. In this case, the slope of a line passing through (1, 0.1) and (7, 26.8) is found to be 4.45.

The slope of a line passing through two points (x₁, y₁) and the (x₂, y₂) can be calculated using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

Plugging in the values of the points (1, 0.1) and (7, 26.8) into the formula, we get:

m = (26.8 - 0.1) / (7 - 1) = 26.7 / 6 = 4.45

Therefore, the slope of the line passing through the points (1, 0.1) and (7, 26.8) is 4.45.

Answers

Answer: D

Step-by-step explanation:

Confidence interval is written as

Sample proportion ± margin of error

Margin of error = z × √pq/n

Where

z represents the z score corresponding to the confidence level

p = sample proportion. It also means probability of success

q = probability of failure

q = 1 - p

p = x/n

Where

n represents the number of samples

x represents the number of success

From the information given,

n = 50

x = 32

p = 32/50 = 0.64

q = 1 - 0.64 = 0.36

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.9 = 0.1

α/2 = 0.01/2 = 0.05

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.05 = 0.95

The z score corresponding to the area on the z table is 2.05. Thus, confidence level of 90% is 1.645

Therefore, the 90% confidence interval is

0.64 ± 1.645√(0.64)(0.36)/50

Suppose that in solving an equation over the interval [0 comma 360 degrees )[0,360°)​, you reach the step sine theta equals negative one halfsinθ=− 1 2. Why is minus−30degrees° not a correct​ answer?

Answers

Final answer:

The angle -30 degrees is not a correct answer because it falls outside of the given interval [0, 360 degrees). The correct answer is theta = 210 degrees, which satisfies the equation sine theta = -1/2 over the interval. In the fourth quadrant, the angle whose sine is -1/2 should be in the third quadrant to satisfy the inequality sine theta <= 0.

Explanation:

In solving the equation Σ theta = -1/2, the student is looking for the values of theta that satisfy the equation over the interval [0, 360 degrees). The value -30 degrees is not a correct answer because it falls outside of the given interval. To find the correct answer, we need to determine the values of theta that make sine of theta equal to -1/2.

To find an angle whose sine is -1/2, we can look at the unit circle. In the first and second quadrants, the sine function is positive, so we need to look in the third and fourth quadrants.In the third quadrant (180 to 270 degrees), the sine function is negative. The angle whose sine is -1/2 in this quadrant is theta = 210 degrees.In the fourth quadrant (270 to 360 degrees), the sine function is positive again. However, the angle whose sine is -1/2 should be in the third quadrant to satisfy the inequality sine theta <= 0. Therefore, -1/2 is not a valid value for sine theta in the fourth quadrant.

This is the initial tableau of a linear programming problem. Solve by the simplex method.

Answers

Answer:

Step-by-step explanation:

We start by selecting our pivot column as the most negative value on the bottom row.

This means our pivot column is [tex]x_{1}[/tex]. We now generate a new column by diving our pivot value by our value on the right-most column. This gives us (on a new row)

P/V

12/1 = 12

4/2 = 2

4/1 = 4

We pick our smallest positive value to be our pivot row.

This means our pivot row is our second row, and our pivot column is our first column. We now divide our entire row by our pivot point (our intersection of these two pivots)

This gives us our new second row as

1 3 0 1/2 0 0 2

now we need to eliminate our [tex]x_1[/tex] values from our other rows.

old row 1 - new row 2 gives us new row 1

row two stays the same

old row 3 - new row 2 gives us new now 3.

old row P + 2 new row 2 gives us new row P  

After the first iteration of this algorithm this gives our tableau as: (see attached screenshot)

Step-by-step explanation:

Two events are dependents event if the occurrence of one of them has effect on the probability of the other.

If A and B are dependents,

then,

P(AB)=P(A)P(B).

Given that,

There are 27 chocolates in a box.

Number of nuts chocolates = 4

Number of caramel chocolates = 8

Number of solid chocolates= 15.

The probability of that a solid candy is drawn is

A survey of 47 people was conducted to compare their self-reported height to their actual height. the difference between reported height and actual height was calculated. you're testing the claim that the mean difference is greater than 1. from the sample, the mean difference was 1.2, with a standard deviation of 0.78. calculate the test statistic, rounded to two decimal places

Answers

Answer: The test statistic is 1.75.

Step-by-step explanation:

Since we have given that

n = 47

First mean difference = 1

and second mean difference = 1.2

Standard deviation = 0.78

So, the value of test statistic would be

[tex]t=\dfrac{\bar{x_1}-\bar{x_2}}{\dfrac{\sigma}{\sqrt{n}}}\\\\t=\dfrac{1.2-1}{\dfrac{0.78}{\sqrt{47}}}\\\\t=\dfrac{0.2}{0.114}\\\\t=1.754[/tex]

Hence, the test statistic is 1.75.

Final answer:

The test statistic for the sample showing the difference between reported and actual height, with a mean difference of 1.2 inches, standard deviation of 0.78, and sample size of 47, is 1.96 when rounded to two decimal places.

Explanation:

The test statistic for a sample where the population standard deviation is unknown and the sample size is small can be calculated using a t-test. The formula for the test statistic in a one-sample t-test is t = (\bar{X} - \mu) / (s/\sqrt{n}), where \bar{X} is the sample mean, \mu is the population mean under the null hypothesis, s is the sample standard deviation, and n is the sample size.

In this case, we are testing the claim that the mean difference in reported and actual height is greater than 1 inch. The null hypothesis (H0) is that the mean difference is less than or equal to 1 inch, and the alternative hypothesis (H1) is that the mean difference is greater than 1 inch. Given a sample mean difference of 1.2, a sample standard deviation of 0.78, and a sample size of 47, the test statistic is calculated as follows:

t = (1.2 - 1) / (0.78/\sqrt{47})

After calculating and rounding to two decimal places, the test statistic is approximately 1.96

construct a 95% prediction interval for y given x=-3.5, ^y= 2.097x - .552 and se= .976​

Answers

Answer:

95% Confidence interval for y

= (-9.804, -5.979)

Lower limit = -9.804

Upper limit = -5.979

Step-by-step explanation:

^y= 2.097x - 0.552

x = -3.5

Standard error = 0.976

Mathematically,

Confidence Interval = (Mean) ± (Margin of error)

Mean = 2.097x - 0.552 = (2.097×-3.5) - 0.552 = - 7.8915

(note that x=-3.5)

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error of the mean)

Critical value for 95% confidence interval = 1.960

Standard Error of the mean = 0.976

95% Confidence Interval = (Mean) ± [(Critical value) × (standard Error of the mean)]

CI = -7.8915 ± (1.960 × 0.976)

CI = -7.8915 ± 1.91296

95% CI = (-9.80446, -5.97854)

95% Confidence interval for y

= (-9.804, -5.979)

The area of the triangle is 35 square feet. Use a quadratic equation to find the length of the base. Round your answer to the nearest tenth.

Answers

Answer:

10.6 ft

Step-by-step explanation:

The complete question is:

The area of the triangle is 35 square feet. Use a quadratic equation to find the length of the base. Round your answer to the nearest tenth.Base=x+4 Height=x

SOLUTION:

As you know, Area of triangle 'A' = 1/2 x b x h

Where,

Base 'b' = x+4

Area 'A' = 35 ft²

Height 'h'= x

35 = (1/2)(x+4)x

35 =(x² + 4x)/2

2 * 35 =x² + 4x

70 = x² + 4x

x² + 4x - 70=0

Formula for the quadratic equation is

x = [- b ± √(b² - 4ac)]/2a

Where,

a=1,  b= 4,   c=-70

Plugging in the values.

x = [- 4 ± √4² - (4 × 1 × - 70)] / (2 × 1 )

x = [- 4 ± √(16  + 280)]/2

x = [- 4 ± √296]/2

x = (- 4 + 17.2)/2 or x = (- 4 - 17.2)/2

x = 13.2/2 or x = - 21.2/2

As, we choose to ignore negative value of 'x'

Therefore, x = 13.2/2 = 6.6

And, Length of the base will be:

x + 4 = 6.6 + 4 => 10.6 ft

The base is approximately 10.6 feet when rounded to the nearest tenth.

We know the area of the triangle is 35 square feet, the base is x + 4, and the height is x.

The formula for the area of a triangle is:

Area = 1/2 × base × height

1. Substitute the given values into the formula:

35 = 1/2 × (x + 4) × x

2. To simplify, multiply both sides by 2 to eliminate the fraction:

70 = (x + 4) × x

3. Expand the equation:

70 = [tex]x^{2}[/tex] + 4x

4. Rearrange into a standard quadratic form:

[tex]x^{2}[/tex] + 4x - 70 = 0

5. To solve this quadratic equation, we can use the quadratic formula:

x = (-b ± √([tex]b^{2}[/tex] - 4ac)) / 2a

6. Here, a = 1, b = 4, and c = -70. Plug these values into the formula:

x = (-4 ± √([tex]4^{2}[/tex] - 4(1)(-70))) / 2(1)

x = (-4 ± √(16 + 280)) / 2

x = (-4 ± √296) / 2

x = (-4 ± 17.2) / 2

7. This gives us two potential solutions:

x = (-4 + 17.2) / 2 ≈ 6.6

x = (-4 - 17.2) / 2 ≈ -10.6 (This solution is not valid since the height cannot be negative)

8. So, the height (x) is 6.6 feet. Therefore, the length of the base is:

Base = x + 4 ≈ 6.6 + 4 = 10.6 feet.

Question- The area of the triangle is 35 square ft. Use a quadratic equation to find the length of the base. Round your answer to the nearest tenth. Base = x + 4, Height = x.

                                                = 150 times

Distance covered by the tire when it revolves 1 time = 2.8 m

Distance covered by the tire when it revolves 150 times = 2.8 [tex]\times[/tex] 150

                                                                                             = 420 meters

Therefore, Benjamin travels 420 meters in 100 seconds.

Divide 3 to both sides:

n = 27

Step-by-step explanation:

Final answer:

The smaller number is 15.

Explanation:

To find the smaller number, let's assign variables to the two numbers. Let's call the larger number 'x' and the smaller number 'y'. According to the given information, we have two equations:

x + y = 39

2x + 3y = 93

To solve this system of equations, we can use the method of substitution.

Rearrange the first equation to get x = 39 - y.

Substitute this expression for x into the second equation:

2(39 - y) + 3y = 93

Now, simplify and solve for y:

78 - 2y + 3y = 93

y = 15

Therefore, the smaller number is 15.

What is the measure of Arc NM?
a: 55
b: 60
c: 120
d: 125
please help ive been stuck on this question for so long i dont understand how to do this

Answers

Answer:

  a:  55°

Step-by-step explanation:

The measure of arc NM is the same as the measure of the central angle that intercepts it: Q. The sum of the central angles of a circle is 360°, so ...

  Q = 360° -120° -60° -65° -60° = 55°

The measure of arc NM is 55°.

Work out the area of this semicircle take pie to be 3.142 and write down all the digits given by your calculator 18cm

Answers

Final answer:

The area of the semicircle is 0.051 square meters.

Explanation:

The area of a semicircle can be found using the formula A = πr²/2, where r is the radius of the semicircle. In this case, the radius is given as 18 cm. So, substituting this value into the formula, we get A = 3.142 x (18 cm)²/2. Now, let's calculate the area step by step:

Convert the radius to meters: 18 cm = 0.18 m

Square the radius: (0.18 m)² = 0.0324 m²

Multiply by π and divide by 2: 0.0324 m² x 3.142 / 2 = 0.051 m²

Therefore, the area of the semicircle is 0.051 square meters.
