During the month of June, Ava kept track of the number of days she saw birds in her garden.she saw birds on 18 days of the month. what is the experimental probability that she will see birds in her garden on july 1?

Answers

Answer 1

An experimental probability value can be set up in the form of a fraction. The part (numerator) is the number of days she saw birds during the month of June. The whole (denominator) is the number of days in the month of June. Since this an experimental probability example, we can use the results from the month of June to assume she will see the same amount of birds in July.

[tex] \frac{Days she saw birds in June}{Days in June} [/tex]

= [tex] \frac{18}{30} [/tex]

= [tex] \frac{3}{5} [/tex]

So the probability she will see birds in her garden on July 1st is [tex] \frac{3}{5} [/tex]

Answer 2

Experimental probability is based on the observations of the past. She saw birds for 18 days out of 31 total days in June. The experimental probability would be 18/31 or a 58.06% chance of seeing a bird on July 1st.

The perimeter of a rectangle is 60 meters.if the length of the rectangle is 14 meters.what is the width of the rectangle?

Answers

Hello!

We know that the formula for perimeter of a rectangle is:

P = 2l + 2w

We've been given enough information to solve this question!

The perimeter of the rectangle is 60 metres, and the its length is 14 meters long.

We must multiply the length by 2 and then subtract it from the perimeter to find the width.

W = P - 2l

W = 60 - 2(14)

W = 32

Therefore, the width of the rectangle is 32 metres long.

Final answer:

To find the width of a rectangle given its length and perimeter, apply the formula for the perimeter of a rectangle and solve for the width.

Explanation:

The width of the rectangle can be found by using the formula for the perimeter of a rectangle:

P = 2(length + width)

Given that the length is 14 meters and the perimeter is 60 meters, you can substitute these values to find the width.

60 = 2(14 + width)

60 = 28 + 2w

2w = 32

w = 16

Therefore, the width of the rectangle is 16 meters.

A cross section of an attic is shaped like a trapezoid. It has an area of 37.4 square meters one base is 6.4 meters and the other base is 12.3 meters long. What is the height of the cross section

Answers

To find the height, you will utilize the formula for area of a trapezoid. A = h(b1 +b2)/2. h is the height, b1 is the the first base, and b2 is the second base. When you substitute the information given to us in the question, the equation that needs solved is 37.4 = h(6.4 + 12.3)/2. You should multiply both sides by 2 to undo the dividing by 2. This gives you 74.8 = h (18.7). To solve for the height, divide both sides by 18.7. This gives us a cross sections height of 4 meters. This is the answer!

Final answer:

To find the height of the trapezoid, use the formula for the area of a trapezoid which is (1/2) x (sum of bases) x height. Calculate the height by substituting the given values for the area, and the lengths of the bases into the formula to find the height as 4 meters.

Explanation:

Area of a trapezoid = (1/2) x (sum of bases) x height

Given area = 37.4 m², base1 = 6.4 m, base2 = 12.3 m

37.4 = (1/2) x (6.4 + 12.3) x h

37.4 = (1/2) x 18.7 x h

h = (37.4 x 2) / 18.7 = 4 meters

Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Find the slope,including units, and write a sentence to interpret the slope in detail. Write an equation for the water level, y, after x days. In how many days will the water level be 26 feet? Graph the equation

Answers

Final answer:

Explanation of slope, equation, and days to reach a specific water level in a river.

Explanation:

Slope: The slope represents the rate of change in water level per day. In this case, the slope is -0.5 feet/day, indicating that the water level is decreasing by 0.5 feet each day.

Equation: The equation for the water level after x days is y = 34 - 0.5x.

Days to reach 26 feet: To find when the water level will be 26 feet, you can solve the equation 26 = 34 - 0.5x to get x = 16 days. Therefore, it will take 16 days for the water level to reach 26 feet.

The cost of going to the big playland park for a family is given by C = 15x + 50, where C represents the cost and x represents the number of family members. How many family members went if it cost them $125?

Answers

As you have already given the equation and what each variable represents, I'll restate it here;
C = 15x + 50; C represents the total cost, and X represents the number of family members.
The total cost was $125, so we should substitute C with 125.

125 = 15x + 50; now, all we have to do is solve for x with basic algebra.
First, let's isolate the variable, so subtract 50 from both sides of the equation.

15x = 75; divide both sides by 15 to solve for x, the number of family members that went to the park.
15x / 15 = x
75 / 15 =5

We are left with the following solution:
x = 5

We can conclude that 5 family members went to the park.

Rebecca left her house and walked 2 blocks east. She turned and walked 5 blocks north to get to the library. If each block is 1/4 of a mile, how far is he direct route from Rebecca’s house to the library?

Answers

Rebecca's direct route from her house to the library is approximately 1.35 miles, calculated using the Pythagorean theorem with her eastward walk of 0.5 miles and northward walk of 1.25 miles (2 blocks east and 5 blocks north, each block being 1/4 mile).

To find the direct route from Rebecca's house to the library, we can use the Pythagorean theorem since the distance forms a right triangle.

First, we calculate the distance Rebecca walked east: 2 blocks * (1/4 mile/block) = 1/2 mile.

Then, we find the distance she walked north: 5 blocks * (1/4 mile/block) = 5/4 miles.

Next, we square both distances: (1/2)^2 = 1/4 and (5/4)^2 = 25/16.

Now, we add these squares together: 1/4 + 25/16 = 16/64 + 100/64 = 116/64.

Taking the square root gives us the direct route distance: √(116/64) ≈ √1.8125 ≈ 1.35 miles.

So, the direct route from Rebecca's house to the library is approximately 1.35 miles.

How many correct answers does Marna need to win the game?

Answers

1. So, Arthur already earned $136, and he needs more money, atleast $189, to buy a new coat. T, will be the amount he needs to earn next week.
136+T≥189
For this inequality and to solve it, we can just subtract 136 from each side so we can get T by itself.
T≥53
So he needs atleast $53 to buy the coat.

2. This problem involves multiplication since you score -5 each time. She wants a score less than -80, so not -80. P will be the number of correct answers she will need. Also since she wants it to be less than -80, you would use <.
-5p<-80
Now we need to divide each side by -5. But, the rule with an inequality is if you're dividing or multiplying by a negative, you have to switch the sign. The sign will be >.
p>16
She needs more than 16 correct answers to win the game.

Zan's percent error was 12% (12 / 100 x 100)

Answer: Garrick's plant is shorter than Zan's plant.

Each millimeter of error results in a 11.11% percent error.

Garrick's measurement was 2 millimeters off and Zan's was 12 millimeters off.

Garrick's measurement was 20% off and Zan's was 12% off.

Step-by-step explanation:

Since we have given that

In case of Garrick's plant:

Actual height of his plant = 10 mm

Measured height of his plant = 8 mm

In case of Zan's plant :

Actual height of his plant = 100 mm

Measured height of his plant = 88 mm

So, clearly Garrick's plant is shorter than Zan's plant.

Difference in actual height of plants of Garrick and Zan is

[tex]100\ mm-10\ mm=90\ mm[/tex]

similarly, difference in measured heights of plants of Garrick and Zan is

[tex]88\ mm-8\ mm\\\\=80\ mm[/tex]

Percent error will be

[tex]\frac{90-80}{90}\times 100\\\\=\frac{10}{90}\times 100\\\\=11.11\%[/tex]

So, Each millimeter of error results in a 11.11% percent error.

Error in Garrick's plant :

[tex]Actual-Measured\\\\=10-8\\\\=2\ mm[/tex]

Percent error is given by

[tex]\frac{2}{10}\times 100\\\\=20\%[/tex]

Similarly,

Error in Zan's plant ;

[tex]Actual-Measured\\\\=100-88\\\\=12\ mm[/tex]

Percent error is given by

[tex]\frac{12}{100}\times 100\\\\=12\%[/tex]

Garrick's measurement was 2 millimeters off and Zan's was 12 millimeters off.

So, Garrick's measurement was 20% off and Zan's was 12% off.

What is the inverse function of a(b)=12•b+9/2

Answers

Final answer:

To find the inverse of the function a(b) = 12b + 9/2, swap 'a' and 'b', then isolate 'b' by subtracting 9/2 and dividing by 12. This gives the inverse function as a = (b - 9/2) / 12.

Explanation:

To find the inverse of a function, you need to rearrange the equation so that the independent variable 'b' becomes the dependent variable. In your function, a(b) = 12b + 9/2, first you need to solve for 'b'. Here are the steps:

Swap 'a' and 'b' to get: b = 12a + 9/2 Isolate 'b' by subtracting 9/2 from both sides: b - 9/2 = 12a Divide both sides by 12 to solve for 'a': a = (b - 9/2) / 12

So the inverse function of a(b) = 12b + 9/2 is a = (b - 9/2) / 12.
