Answer:
- 7, - 28, - 112, - 448, - 1792, - 7168
Step-by-step explanation:
Using the recursive formula and a₁ = - 7 , then
a₂ = 4a₁ = 4 (- 7) = - 28
a₃ = 4a₂ = 4(- 28) = - 112
a₄ = 4a₃ = 4(- 112) = - 448
a₅ = 4a₄ = 4(- 448) = - 1792
a₆ = 4a₅ = 4(- 1792) = - 7168
Answer:
Use a calculator to divide the two values (small over big) to get 14/35 = 0.4
Now multiply that result by 100 to convert to a percentage
0.4*100 = 40%
he has ridden 40% of the course so
1. would have to be team E because add up all the numbers 1058/8 (which is how many numbers that is there) 132.25.
2. (More of an explanation if you still don't understand)
52+52+53+54+55+55=321/6=53.5
52+53+54+55+57+57=328/6=54.66 repeated rounded to 54.7 so your answer is 1.2
Complete question :
Standardized tests: In a particular year, the mean score on the ACT test was 19.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 532 and the standard deviation was 128. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Part: 0/4 Part 1 of 4 (a) Find the z-score for an ACT score of 26. The Z-score for an ACT score of 26 is
Answer:
1.26
Step-by-step explanation:
Given that:
For ACT:
Mean score, m = 19.3
Standard deviation, s = 5.3
Zscore for ACT score of 26;
Using the Zscore formula :
(x - mean) / standard deviation
x = 26
Zscore :
(26 - 19.3) / 5.3
= 6.7 / 5.3
= 1.2641509
= 1.26
Answer: 706.5
Step-by-step explanation:
First you have to square the radius. So for this question you multiply 5x5. That makes 25. Then you multiply that with pi ( 3.14 ) and that makes 78.50. Next you multiply it by 9, that makes 706.5.
