Answer:

0.0802

Step-by-step explanation:

Calculation for the p-value

Based on the information given this is a two tailed test

Hence,

p(z< -1.75)= 0.0401

p(z> 1.75) = 0.0401

Now let calculate the p-value

p-value=2* 0.0401

p-value= 0.0802

Therefore If the value of the test statistic z equals 1.75 the p-value will be 0.0802

In order to answer this one, it's really really really really helpful if you know what the law of cosines says. In fact it's absolutely necessary. The law of cosines says if you know two sides of a triangle and the angle between them then you can use that information to find the length of the third side. In the picture you know the lengths of two sides and you know the angle between them. So you can use the law of cosines to find the length of the third sidethat. That's side AC.

The sum of five consecutive integers equals 5.5 times the middle integer. Find the integers.
kogti [31]

The five consecutive integers are -2, -1, 0, 1 and 2.

<h3>What are the values of the integers?</h3>

Given that;

The sum of five consecutive integers equals 5.5 times the middle integer.

Since the integers are consecutive, let the integer be;

x, x+1, x+2, x+3 and x+4.

Now, sum of the integers equals 5.5 times the middle integer.

Middle integer is x+2.

Hence we have;

x + x+1 + x+2 + x+3 + x+4 = 5.5( x+2 )

x + x+1 + x+2 + x+3 + x+4 = 5.5x + 11

We collect like terms

x + x + x + x + x - 5.5x = 11 - 1 - 2 - 3 - 4

5x - 5.5x = 1

-0.5x = 1

x = -( 1 / 0.5 )

x = -2

Since our integers are; x, x+1, x+2, x+3 and x+4.

We substitute in the value of x

x = -2

x+1 = -2 + 1 = -1

x+2 = -2 + 2 = 0

x+3 = -2 + 3 = 1

x+4 = -2 + 4 = 2

Therefore, the five consecutive integers are -2, -1, 0, 1 and 2.
