Answer:
d. Twenty-five cars are randomly selected with the new transmission and 25 with the old transmission.
Step-by-step explanation:
A hypothesis test on the difference between the means must satisfy the following conditions
1) the samples must be randomly selected
2) each sample must have a known standard deviation
3) the samples must be independent
4) the samples must be from normal distribution
Hence only part d gives the right answer.
Your equation would be t +25=57 because we don’t know how many necklaces Stacy made so we use T to plug it in and solve
Answer:
79°
Step-by-step explanation:
since this figure goes around completely, the sum would be 360°
1 and 3 are equal, so you would multiply 101 by 2
101 × 2 = 202
subtract 202 from 360
360 - 202 = 158
4 and 2 are equal, so divide 158 by 2
158 ÷ 2 = 79
so angle 4 = 79°
43 is a prime number, so
it has factors only 1 and 43, You can write only 43*1=43.
- i =
- Product rule of radicals: √ab = √a x √b
Firstly, factor out i:
Next, apply the product rule of radicals here as such:
<u>Your answer is 5i√2, or the second option.</u>
