Answer:
30 blocks
Step-by-step explanation:
60 minutes = 1 hour
For one hour, she will walk 7.5 blocks.
The rate is 7.5blocks per hour.
Multiply this by 4 hours, and you will get 30 blocks.
(7.5)4 = 30
In your case 85 has repeated 3 times 70 has repeated 2 times and 95 has repeated 3 times if you still don’t understand my number is 8177074197 I can try to help you a little more.
Answer:
Step-by-step explanation:
The probability an electric motor is defective is 5%. This means that the probability of success, p = 5/100 = 0.05
The probability of failure, q = 1 - p = 1 - 0.05 = 0.95.
number of samples is 100, so n = 100
We would apply binomial distribution. The formula for binomial distribution is expressed as
P(x = r) = nCr × q^(n - r) × p^r
We want to determine the probability that there would be no defective. This is expressed as
P(x = 0) = 100C0 × 0.95^(100- 0) × 0.05^0 = 1 × 0.0059 × 1 = 0.006
Answer:
measure of arc ABC = 283°
Step-by-step explanation:
First we have to find y
7y - 7 + 4y + 6 +20y - 11 = 360
31y - 12 = 360
31y = 372
y = 12
Since all the angles are central angles and intercepted arcs of those angles have the same measure,
the measure of arc ABC = 4y + 6 + 20y - 11
= 24y - 5
= 24(12) - 5
= 283
