Easy!!

So, We want the area of the square, and the two trapezoids around it!

Square Formula = b*h

Trapezoid formula = 1/2(b^1+b&2)

First of all, to find the area of the square:

Do 20*12
= 240 in^2

Second of all, to find the area of the trapezoid:

Do 10(12+30)
= 420 in^2

To find the area of the whole banner, add them up!

= 420 + 420 + 240 = 1080

So, The answer should add up to 1080.
The answer is probably "B"

Micayla wants the print shop to reduce the size of her painting but keep the ratio of length to width so that it will fit her fr

marissa [1.9K]

Answer:

The width of the frame must be 12 inches (15in by 12in)

Step-by-step explanation:

Given

See attachment for painting and frame

Required

Determine the dimension of the frame

To do this, we make use of the following scale ratio.

$Scale = Length : Width$

For the painting,

$Scale = 20: 16$

For the frame,

$Scale = 15: w$

Since she wants to maintain the same ratio; both scale must be the same.

i.e.

$15 : w = 20 : 16$

Express as fraction

$\frac{w}{15} = \frac{16}{20}$

$\frac{w}{15} = 0.8$

Make w the subject

$w = 15 * 0.8$

$w = 12$

The width of the frame must be 12 inches i.e. 15in by 12in frame

Assume that women's heights are normally distributed with a mean given by , and a standard deviation given by . μ = 63.5 in σ =

tresset_1 [31]

(a) if 1 woman is randomly selected, find the probability that her height is less than 64 in
using z-score formula:
z-score=(x-mu)/sig
(64-63.5)/2.8
=0.18
thus
P(x<64)=P(z<0.18)-=0.5714

B] if 33 women are randomly selected, find the probability that they have a mean height less than 64 in
using the central limit theorem of sample means, we shall have:
2.8/√33=0.49
since n>30 we use z-distribtuion
z(64)=(64-63.5)/0.49=1.191
The
P(x_bar<64)=P(x<1.191)=0.8830
