Hi there the answers are 3.2, 1.8, 8.6, and 17.12. Pls mark as brainliest!!!!!!
Solution :
It is given that :
(Null hypothesis, is also correct)
(Alternate hypothesis, also called )
This is a lower tailed test,
Therefore,
Sample proportion,
= 0.04
And claimed proportion, P = 0.05
Significance level, = 0.01
Therefore, calculating the statistics, we get
Standard deviation of
Test statistic,
Now since this is a lower tailed test, p-value =
Rejection Criteria : Reject if p-value < α .
Conclusion : Since the p-value , we fail to reject the null hypothesis. There is insufficient evidence that p is less than 0.05
Answer:
They cancel out, so simplified is zero.
Step-by-step explanation:
As it is given here
initial speed is
v_i = 6 m/s
After 4 seconds the final speed is
v_f = 14 m/s
so here we can use the formula of acceleration using kinematics
a = \frac{v_f - v_i}{t}
a = \frac{14 - 6}{4}
a = 2 m/s^2
so here it will accelerate at 2 m/s^2 rate.
Answer:
Step-by-step explanation:
You need to give all the fractions a common denominator so you can compare the numerators.
The least common multiple of 5, 8, 16, 4, 3 is 240.
⅖ = 96/240
⅞ = 210/240
15/16 = 225/240
¾ = 180/240
⅜ = 90/240
⅓ = 80/240
The only numerator between 96 and 210 is 180.
180/240 = ¾
⅖ < ¾ < ⅞
