Answer:

probability that a single car of this model emits more than 86 mg/mi of NOX + NMOG = 0.8668

Step-by-step explanation:

mean, μ = 80 mg/mi

Standard deviation, [tex]\sigma = 4 mg/mi[/tex]

probability that a single car of this model emits more than 86 mg/mi of NOX + NMOG

[tex]P(X > x ) = P(z > \frac{x - \mu}{\sigma})[/tex]

[tex]P(X > x ) =1 - P(z < \frac{x - \mu}{\sigma})[/tex]

[tex]P(X > 86 ) =1 - P(z < \frac{86 - 80}{4})[/tex]

P(X > 86) = 1 - P(z < 1.5)

From the standard normal table, P(z < 1.5) = 0.9332

P(X > 86) = 1 - 0.9332

P(X > 86) = 0.0668

Answer and Step-by-step explanation:

You are correct in that we need to use the Law of Sines: [tex]\frac{c}{sinC} =\frac{b}{sinB}=\frac{a}{sinA}[/tex].

Here, when we use the Law of Sines, we have: [tex]\frac{28}{sin(63)}=\frac{29}{sinB}[/tex].

Cross multiply:

(sinB) * 28 = (sin63) * 29

28sinB ≈ 25.839

sinB ≈ 0.9228

Now, in order to solve for B, we need to use inverse sin ([tex]sin^{-1}[/tex]):

[tex]sin^{-1}(sinB)=sin^{-1}(0.9228)[/tex]

The sines on the left cancel out, and we're left with:

B ≈ 67.3 degrees

Now, one thing to keep in mind when doing Law of Sines is that there is potentially more than one answer possible for the degree measure. The other degree measure can be found by subtracting this one from 180:

180 - 67.3 = 112.7 degrees.

Hope this helps!

Answer:

67.3° , 112.7°

Step-by-step explanation:

sinx = 0.9228

Take inverse of sin, you get:

x = 67.3389176683

Since sin is positive in first two quadrants, second angle is:

180 - 67.3389176683

= 112.6610823317

Answer:

P(X < 7) = 0.76

Step-by-step explanation:

Counting properly from the diagram attached to the question,

number of trials it took her to make less than 7 shots(i.e. 0 to 6 shots) = 38

The total number of trials she made = 50

Probability that it takes fewer than 7 shots to get her first successful shot, P(X < 7) = (number of trials it took to make less than 7 shots)/(Total number of trials)

P(X < 7) = 38/50

P(X < 7) = 0.76

Answer: 18pi unit squared

Step-by-step explanation:

Area of a circle = πr2

Radius of Circle G= 3units

Area of circle G= πr2

= π (3×3)

= 9π unit squared

Maria draws a circle with double the area of circle G. This will be:

2 × 9π

= 18π2

= 18pi unit squared

Answer:

18*pi units squared.

Step-by-step explanation:

The area of a circle can be calculated with the following formula:

Area = pi * r^2

Where r is the radius.

The circle G have a radius of 3 units, so its area is:

Area1 = pi * r^2 = pi * 3^2 = 9*pi

If the circle that Maria draws has double the area, so her circle have a area of:

Area2 = 2 * Area1 = 2*9*pi = 18*pi units squared.

Answer:

The point estimate of the population mean is $20 per week. The 95% confidence interval, using a z-score of 1.96, ranges from $18.20 to $21.80.

The subject of this question deals with the statistical concept of confidence intervals. The point estimate of the population mean is simply the sample mean, which is $20 per week. To calculate the confidence interval for the population mean (μ), we first need to understand that for a 95% level of confidence, the z-score (standard score) is 1.96. This is derived from statistical tables or a z-distribution.

The confidence interval is then calculated with the formula:
(sample mean - (z-score * (standard deviation/√sample size)), sample mean + (z-score * (standard deviation/√sample size))
Substituting the known values in, the 95% confidence interval for μ is ($18.20, $21.80).

The point estimate of the population mean is the sample mean of $20 per week. Using the given standard deviation and applying the formula for a 95% confidence interval, we determine the confidence interval for the population mean to be ($18.6, $21.4).

The point estimate of the population mean ( μ) is the sample mean which is $20 per week. To calculate the confidence interval, we can use the formula for a 95% confidence interval when the population standard deviation ( σ) is known:

CI = Y ± Z*( σ/ √n)

Given that σ = $5, n = 49, Z for a 95% confidence level is approximately 1.96. Plugging these values into the formula, we get the confidence interval:

CI = 20 ± 1.96*(5/√49)

CI = 20 ± 1.96*(5/7)

CI = 20 ± 1.96*(0.714)

CI = 20 ± 1.4

CI = (18.6, 21.4)

Therefore, the 95% confidence interval for the population mean ( μ) is ($18.6, $21.4).

A=7 parts every 10 minutes

We know its 1 hour for every 60 minutes

12 hr x 60 min\1 hr is 720 minutes

720 min times 7 part divide by 10 minutes is 504 parts

B= 16 parts every 17 minutes

10 hr times 60 min divide by 1 hour is 600 minutes

600 min times 16 parts divide by 17 minutes is 564.7 parts

4000

Step-by-step explanation:

this can be found by using the equation

cross multiply

40x = 160000

simplify

x= 4000

To find the total number of visitors the art museum had in the month, divide 1,600 by 0.4.

To find the total number of visitors the art museum had in the month, we can use the given information. We know that 1,600 visitors represents 40% of the total number of visitors for the month. To find the total number of visitors, we can set up the following equation:

1,600 = 0.4 * total number of visitors

To solve for the total number of visitors, we divide both sides of the equation by 0.4:

total number of visitors = 1,600 / 0.4 = 4,000

Therefore, the art museum had a total of 4,000 visitors that month.

Square root of 73= 8.54

The value of [tex]\(10^2 - 4^3\)[/tex] is [tex]\(6^2\)[/tex], equivalent to 36.

To solve this expression, first, let's calculate each part:

[tex]$10^2 = 10 \times 10 = 100$[/tex]

[tex]$4^3 = 4 \times 4 \times 4 = 64$[/tex]

Now, we can substitute these values into the expression:

[tex]$10^2 - 4^3 = 100 - 64 = 36$[/tex]

Now, we need to express 36 as a power of 6. We can see that [tex]$36 = 6^2$[/tex], so:

[tex]$36 = 6^2$[/tex]

Therefore, the value of [tex]$10^2 - 4^3$[/tex] as a power of 6 is [tex]$6^2$[/tex]

Answer:

24 cracks will be filled

Step-by-step explanation:

Here, the first question asks how to convert 3 pounds to ounces.

we can do this using a mathematical approach. To convert pounds to ounces, we need to know that there are 16 ounces in a pound. so to convert pounds to ounces, we just need to multiply the number of pounds we have by 16 to get the equivalent number of ounces.

The second question asks to give the number of cracks that be repaired.

From the question, we were made to know that each of the cracks would eat up 2 pounds of cement to be filled.

Let’s calculate the amount of cement we have. That would be 3 * 16 = 48 ounces of cement.

The amount of cracks to be filled is thus 48 ounces/2 ounces = 24 cracks

Answer: They won 22 gold, 18 silver and 12 bronze.

Step-by-step explanation: Suppose gold is g, silver is s and bronze is b.

The number of silver was 6 less than twice of bronze: s = 2b - 6

Gold was 4 more than silver: g = s + 4

Total is 52: g + s + b = 52

We have 3 equations and 3 variables. To determine each one:

s = 2b - 6 (1)

g = s + 4 (2)

g + s + b =52 (3)

Substitute (1) in (2):

g = 4 + 2b - 6

g = 2b - 2 (4)

Using (1) and (4), substitute in (3)

2b - 2 +2b - 6 + b = 52

5b = 52+8

b= [tex]\frac{60}{5}[/tex]

b = 12

With b, we find s:

s = 2.12 - 6

s = 18

With s, we find g:

g = 4 + 18

g = 22

Therefore, the team won 22 gold, 18 silver and 12 bronze.

Answer:

Gold : 22 medals , Silver : 18 medals, Bronze : 12 medals

Step-by-step explanation:

Solution:-

- Denote the total number of medals won by USA, T = 52

- The number of bronze medals = x

- The number of silver medals = y

- The number of gold medals = z

- We are given that number of silver medals (y) was 6 ​fewer (less)​ than twice the number of bronze medals (x). So the mathematical representation of this observation would be:

                                  y = 2x - 6  

- Similarly, the number of gold medals (z) was ​four more than​ the number of silver medals (y).  So the mathematical representation of this observation would be:

                                 z = y + 4

- The total number of medals T:

                                T = x + y + z

- We have 3 equations and 3 unknowns. Solve the equations simultaneously,

                                z = 2x - 6 + 4 = 2x - 2

                                T = x + ( 2x - 6 ) + ( 2x - 2)

                                52 = 5x - 8

                                5x = 60

                                x = 12 bronze medals

                                z = 2x - 2

                                z = 2*12 - 2

                                z = 22 gold medals

                                z = y + 4

                               y = 22 - 4

                               y = 18 silver medals
