Answer:
i think its $74.92
Step-by-step explanation:
You can travel 8km in one hour.
we know that in 5 hr you travel 400 km
then just divide 400/5=8
Answer:
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
Step-by-step explanation:
Alpha, α = 0.05
We conduct a hypothesis test at 5% significance level.
The null hypothesis will be rejected when
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
- When a 95% confidence interval is constructed,it contains all the possible values for the parameter being estimated.
- If the value of the parameter stated in the null hypothesis is contained in the 95% confidence interval, then we fail to reject the null hypothesis 0.05 level and accept it.
- If the value stated in the null hypothesis is not in the interval, then we fail to accept the null hypothesis and reject the null hypothesis at the 0.05 level.
Find 20% of 240.
Of means to multiply.
20% has to be changed to a decimal.
.20 * 240 = 48
The coordinate of point P is (-6, -2)
<h3>How to determine the coordinate of P?</h3>
The given parameters are:
P lies 2 units below the x-axis and its x-coordinate is three times its y-coordinate
The above means that
y = -2 i.e. 2 units below the x-axis
x = 3y
This gives
x = 3 * -2
Evaluate
x = -6
Express as cooridnates
P = (-6, -2)
Hence, the coordinate of point P is (-6, -2)
