Answer:

y = 7.99x

Step-by-step explanation:

If y = total cost and x = dozen of cookies

Then y = 7.99x

This is because the price of the number of dozens of the cookies, multiply by the price of i dozen will be equal to the total cost price

A sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's p

Answer:

So the value of the test statistic is -0.85.

Step-by-step explanation:

We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.

We get that:

$n=1800\\\\p_1=53\%=0.53\\\\p_2=54\%=0.54\\$

We calculate the standar deviation:

$\sigma=\sqrt{\frac{0.53 \cdot (1-0.53)}{n}}=\sqrt{\frac{0.53 \cdot 0.47}{1800}}=0.01176$

We calculate the value of the test statistic:

$z=\frac{p_1-p_2}{\sigma}=\frac{0.53-0.54}{0.01176}=-0.85$

So the value of the test statistic is -0.85.

the perimeter of a rectangular garden is 50 meters and area is 150 meters square . calculate the length and breadth of the garde

makkiz [27]

Answer: The two sides are 15m and 10m.

Step-by-step explanation:

Area = l x w

150 = l x w

There are two solutions for l

l 1= P/4+1/4√P2﹣16A

=50/4+1/4·√50^2﹣16·150=15m

l2 = P/4﹣1/4√P2﹣16A

=50/4﹣1/4·√50^2﹣16·150=10m
