LenaWriter [7]

It is given that the scale model of a rectangular garden is 1.5 ft by 4 ft. The scale model is enlarged by a scale factor of 7 to create the actual garden.

Therefore, we can see clearly that the width of the scale model is 1.5 feet. Hence, the width of the actual garden which has been enlarged by a scale factor of 7 will be 7 times the width of the scale model.

Thus the width of the actual garden will be: 1.5\times 7=10.5 feet

In a similar fashion the length of the actual garden will be 4\times 7=28 feet

Thus, the area of the actual garden will be:

Area=Length\times width=10.5\times 28=294 ft^2

As we can see, out of the given options, the last option is the correct one.

8. The heights of female students at North Shore High School are normally distributed with a mean of 175 cm and a standard devia
gulaghasi [49]

The number of students with heights less than 163 cm should be expected is 12.

According to the statement

The mean of height is 175 cm

and  the standard deviation of height is 6 cm.

We use normal distribution here with formula

Z= X - μ /σ

Here X is 167.5 and μ is 175 and σ is 6 cm.

Substitute the values in it then

Z = 167.5 - 175 / 6

Z = -1.25

-1.25 have a p value 0.012

Out of 1000 students:

0.012 x 1000 = 12.

So, The number of students with heights less than 163 cm should be expected is 12.
