Solve the inequality , find the max possible value for the variable.

3t + 1 < t + 12

2t < 11

t < 5.5

t_max = 5.5

For the second question just solve as two separate inequalities

4 +2 < x <= 7 + 2

6 <x <= 9

x in ]6, 9]

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 23.2 pounds and

erica [24]

Answer:

The standard deviation of the sampling distribution of sample means would be 0.8186.

Step-by-step explanation:

We are given that

Mean of population=23.2 pounds

Standard deviation of population=6.6 pounds

n=65

We have to find the standard deviation of the sampling distribution of sample means.

We know that standard deviation of the sampling distribution of sample means

= $\frac{\sigma}{\sqrt{n}}$

Using the formula

The standard deviation of the sampling distribution of sample means

= $\frac{6.6}{\sqrt{65}}$

$=0.8186$

Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.

G(x) = x4 − 4x2 + 7x − 8?

blagie [28]

Answer:

to put in the value of any variable in this equation(for example 2 ) we will write it as

g(2) = 4(2) - 4(2)^2 + 7(2) -8

g(2) = 8 - 16 + 14 - 8

g(2) = -2

Translate the sentence into an equation. The sum of 3 times a number and 7 is 19.

klemol [59]

D. Because you're multiplying 3 by a number which is what the variable represents (n), then you're just adding 7 to that which equals 19 all together. It all translates to 3n+7=19.

a football team gains 8 yards in one play, loses 5 yards in the next. What is the teams total yardage for the two plays

Ann [662]

The team gained a total of 3 yards. That is because they first gained 8 (0 + 8), then lost 3 (8 - 3).
