Using the t-distribution, the t-statistic for the two-sided test would be of t = 0.7.
<h3>What is the test statistic for a t-distribution hypotheses test?</h3>
The test statistic is given by:
The parameters are:
- is the sample mean.
- is the expected value.
- s is the standard deviation of the sample.
The values of the parameters are given as follows:
.
The sample mean is:
Hence the test statistic is:
t = 0.7.

Answer:I think it’s option 2, light blue
Step-by-step explanation:
Answer:
Hmax = 269.76 feet
Step-by-step explanation:
This movement is vertical shot up.
We will accept value of g= 10m/s², but we must convert meters in the feets.
We know that 1 meter = 3.28 feets => 10meters = 32.8 feets
According to this g= 32.8 feet/s²
A flare is launched upwards from the height platform H₁ = 20 feet.
Initial velocity is 128 feet per second, when the flare reaches the highest point the final velocity is zero.
We will marked velocity with V and use this formula
V₀² - V² = 2 · g · H₂ and V= 0 => V₀² = 2 · g · H₂ => H₂ = V₀²/ 2 · g
H₂ = 128² / 2 · 32.8 = 16384 / 65.6 = 249.76 feet
The highest point in feet , that the flare reaches is:
Hmax = H₁ + H₂ = 20 + 249.6 = 269.6 feet.
God with you!!!
A. 1/5
All the points are simply divided by 5 to get the answer. If it were -1/5, then the new points would be negative. (Or positive for the points initially negative).
Answer:
Question 58: 130.4
Question 59: x = 21
Question: 60: 60
Step-by-step explanation:
Question 58: A bisector cuts something into two equals halfs. Since <ABD is 65.2, you have to multiply it by two to receive your final answer of 130.4.
Question 59: A right angle is equal to 90 degrees. So 90 split into two is 45. you take the 45 and plug it into the equation: 45 = (2x + 3) to find your answer.
45 = 2x + 3
42 = 2x
21 = x
Question 60: A bisector cuts something into two equals halfs. Since <ABE is 30, you have to multiply it by two to receive your final answer of 60.
