Answer:

26

Step-by-step explanation:

We are told that x=4, which means you will substitute 4 in for every x.

So for 3x, you would do 3(4) because the x = 4. Just substitute 4 in for the x.

3(4) - 6 + 7(4) - 2(4)

Now, you could put that in a calculator or solve it on paper. :) If you're doing it on paper, remember PEMDAS.

12 - 6 + 28 - 8

= 26

A local weather enthusiast wants to see if the last five summers have been warmer than normal for Eloy, Arizona. From the Nation
lys-0071 [83]

Answer:


Step-by-step explanation:

This is a question on hypothesis testing.

Population mean based on 30 year average for July was 90 with

a std deviation of 2.1

Sample of 5 shows average 93.5

To check whether sample average = population average

H0: x bar =90

Ha: x bar not equal 90(Two tailed test)

Test statistic = \frac{93.5-90}{\frac{2.1}{\sqrt{5} } }

=3.73

Since this lies outside the range (-1.96, 1.96) we reject null hypothesis

Hence we cannot say sample mean equals 90

Evaluate 6x + 11 when x = 7
nlexa [21]

Answer:

53

Step-by-step explanation:

To evaluate 6x + 11, we must substitute the value of x.

Since we know that x = 7, it is easier to evaluate the expression;

6x + 11

6(7) + 11

Since 6 is outside the parenthesis, we must multiply everything inside the parenthesis by 6;

6(7) + 11

42 + 11

When you add the two numbers you get:

53
