Answer:
f(0) = g(0)
Step-by-step explanations
if a function h(x) passes through [a,b] then it can be said that h(a)=b.
given that, g(x) passes through (-2,0) and (0,4)
so, g(-2)=0, g(0)=4.
f(x) passes through (0,4) and (2,0)
so, f(2)=0, f(0)=4.
therefore, f(0)=g(0)=4.
so, first option is correct.
Answer:
The correct answer is 4 × x + 72 > 400.
Step-by-step explanation:
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.
The dance will cost $400.
Let x number of tickets the committee could sell.
Total money earned by the committee is 4 × x + 72.
The committee should have some left over money after spending for the spring fling dance which costs $400.
Thus the inequality to determine the number of tickets the committee needs to sell to have money left over after they pay for this year's dance is given by,
4 × x + 72 > 400.
Answer:
b.75
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem:
Mean of the population is 75.
By the Central Limit Theorem,
The mean of the sample, 
, is expected to be also 75.
So the correct answer is:
b.75
y= -1/2x-3
y= -7/3x-5
Slope intercept form is y=mx+b. M is the slope and B is the y-intercept.
