Perimeter is the sum of all the sides for any figure.

In a rectangle opposite sides are equal .If the length and width of rectangle are l and w then Perimeter = 2(l+w)

In the given question

$L= 5 \frac{1}{2}W= 3 \frac{1}{2}$

Perimeter = $2( 5 \frac{1}{2}+3 \frac{1}{2} )=2(\frac{11}{2}+\frac{7}{2} )=2(\frac{18}{2} )=2(9)=18$

Perimeter of rectangular is 18m

2·51/2 + 2·31/2 = 82 m

2·(5 + 1/2) + 2·(3 + 1/2) = 18 m

At the beginning of the month Alice's checking deposit balance was $650 During the month she deposit $300 and withdrew $120 in c

faltersainse [42]

Alice starts off with $650. Next she puts $300 into the bank. This gives us $950. Theeenn she takes out $120 which leaves us with $830. She transfers $125 to her checking which takes away $125. This means 830 - 125 which is 680 or $680. The writes checks for $43 and $28 which mean she looses $43 and $28. Minus the $43 would be $637 and minus the $28 would be $609. At the end of the month Alice has a balance of $609.

A pizza place recently hired additional drivers and as a result now claims that its average delivery time for orders is under 44

Burka [1]

Answer:

Yes, this sample provide enough evidence to support the delivery time claim made by the pizza place.

Step-by-step explanation:

We are given that a pizza place recently hired additional drivers and as a result now claims that its average delivery time for orders is under 44 minutes.

A sample of 39 customer deliveries was examined, and the average delivery time was found to be 40.5 minutes. Historically, the standard deviation for delivery time is 11.3 minutes.

From this, X bar = 40.5 , $\sigma$ = 11.3 , $\mu$ = 44 and sample, n = 39

Null Hypothesis, $H_0$ : $\mu$ >= 44

Alternate Hypothesis, $H_1$ : $\mu$ < 44

The test statistics used here will be;

T.S. = $\frac{Xbar-\mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

So, Test statistics = $\frac{40.5-44}{\frac{11.3}{\sqrt{39} } }$ = -1.93

Now, at 5% significance level the z score table gives critical value of -1.6449 as it is one-tail test.

<em>Since our test statistics is less than the critical value as -1.93 < -1.6449, so we have sufficient evidence to reject null hypothesis and conclude that the average delivery time for orders is under 44 minutes.</em>

Who's most brainiest to answer these 2 questions? Will mark ya'll brainiest. Pls show all work!

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.5

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie.

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.
