Answer:
D
Step-by-step explanation:
Using the rule of exponents
× ⇔ , then
3² × 3³
=
=
= 3 × 3 × 3 × 3 × 3
= 9 × 9 × 3
= 81 × 3
= 243 → D
Answer:
Out of 1000 people who said that they attend a religious service at least once a week, 31 stopped to help a person with car trouble
Of 1200 people interviewed who had not attended a religious service at least once a month, 22 stopped to help a person with car trouble.
We will use Comparing Two Proportions
i.e. religion service makes no difference
i.e. religion service makes difference
Formula of test statistic :
Substitute the values
test statistic :
Refer the z table for p value
p value = 0.9726
α=0.05
p value >α
So, we failed to reject null hypothesis
Hence religion service makes no difference
Answer:
The equation of the line is y = 6x - 14
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (16 - 4)/(5 - 3)
m = 12/2
m = 6
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 4 = 6(x - 3)
y - 4 = 6x - 18
y = 6x - 14
If it's likely to happen, but it's not a certainty, then it has a high chance of happening. Pick P(D).
