Answer:
J - all three
Step-by-step explanation:
an inverse function is simply the same function but now solved by x (and then we switch names of the variables x and y to still have a regular function definition).
let's use I as example
y = 3x - 6
for the inverse function we now solve for x.
y + 6 = 3x
x = y/3 + 2
and to switch names for a regular function definition
y = x/3 + 2
Answer:
25%
Step-by-step explanation:
Given data
original quantity =12
new quantity =15
% increase= new-original/original *100
% increase= 15-12/12 *100
% increase= 3/12 *100
% increase=0.25 *100
% increase=25%
hence the increase is 25%.
Answer:
-10
Step-by-step explanation:
When you have two negatives to subtract,
Just add
4+ 6=10
Then make it a negative
Answer:
Option C is correct.
The test statistic for this question is -3.13
Step-by-step explanation:
To compute the z-test statistic, the formula is given as
z = (x - μ₀)/σₓ
x = p = sample proportion of the 500 college students sampled, that favor reducing the deficit using only spending cuts with no tax increase = (75/500) = 0.15
μ₀ = p₀ = the proportion to be compared against, that is, the proportion of Americans that favor reducing the U.S. budget deficit by using spending cuts only, with no tax increases = 20% = 0.20
σₓ = standard error of the sample proportion = √[p(1-p)/n]
p = 0.15
n = Sample size = 500
σₓ = √[0.15×0.85/500] = 0.01597
z = (0.15 - 0.20) ÷ 0.01597
z = -3.13
