Answer:

The square root pf a number can be simplified only if the number is divisible by a perfect square (other than 1). √12 can be simplified because 12 is divisible by 4 -- a perfect square. But 6 is not divisible by a perfect square, so √6 cannot be simplified further.

artcher [175]

Answer:

12(3y+2x)

Step-by-step explanation:

In this question, we are asked to give an expression that represents the total cost of shorts for the players.

He is ordering 2 pairs of short and 3 shirts. Hence, per player, he would be spending the following:

2 pairs of shorts at x dollars each. Cost here is just $2x

3 shirts at y per one. Cost is $3y

Per player he is spending a total of 3y + 2x

Now, there are people to cater for. The total amount to spend will now be 12(3y + 2z )

Mileage tests are conducted for a particular model of automobile. If a 98% confidence interval with a margin of error of 1 mile

Llana [10]

Answer: 37

Step-by-step explanation:

Given : Significance level : $\alpha:1-0.98=0.02$

Critical value : $z_{\alpha/2}=z_{0.01}=2.33$

margin of error : E= 1 mile per gallon

Population standard deviation: $\sigma=2.6$ miles per gallon.

We know that when the population standard deviation is known then the formula to find the sample size is given by :

$n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2$

$n=(\dfrac{(2.33)\times 2.6}{1})^2=36.699364\approx37$ [Round to the next whole number.]

Hence, the required number of automobiles should be used in the test = 37
