Answer:

A) Zero

Step-by-step explanation:

A good way to tell how many solutions there are in a system of equations, is to look at how many times the equations intersect. In this case, the equations don't intersect so there are no solutions.

In the general population, the mean IQ is 100 with a standard deviation of 15. Dr. Robbins wants to see if a class of statistics

Shalnov [3]

From the information given, a right-tailed test using the z-distribution is appropriate.

At the null hypothesis, it is tested if the class of statistics students is not significantly smarter than the general population, that is, their mean IQ is of at most 100, hence:

$H_0: \mu \leq 100$

At the alternative hypothesis, it is tested if they are significantly smarter, that is, their mean IQ is greater than 100, hence:

$H_1: \mu > 100$

We are testing if the mean is greater than a value, hence it is a right-tailed test.

We have the standard deviation for the population, hence, the z-distribution is used.

A motorist traveled 250 miles on 11 gallons of gas. With the same vehicle, about how far could he go on 16 gallons of gas? Round

363.6

Step-by-step explanation:

250/11= 22.72

22.72 x 16= 363.3636

when rounded tot he nearest tenth its 363.6 because the three is less than five and cannot bump up the 6

Let f(x) = 4x+3 and g(x) = -2x+5

brilliants [131]

f(x) = 4x + 3
g(x) = -2x + 5

(f · g)(5) = (4(5) + 3)(-2(5) + 5)
(f · g)(5) = (20 + 3)(-10 + 5)
(f · g)(5) = (23)(-5)
(f · g)(5) = -115

Y=-2x-3,y=-2x+2 how many solutions does the system have

denis23 [38]

Answer:

3x + 3 = -2x + 3

3x + 2x = 3 - 3

5x = 0

x =0.

So y = 3(0) + 3 = 3.
