Answer:

The correct answer is 90.

Step-by-step explanation:

This is because we need to add up all of the numbers, and see what the mean is between the four numbers. Then we can try adding a different number each time, and then find the mean. 96 + 92 + 94 + 88 + 90 = 460.

460/5 = 92

In a video game, Agnes scored 20% fewer than Amy. Amy scored 860

vovangra [49]

Answer:

$\huge\boxed{\sf Agnes\ Score = 688\ points}$

Step-by-step explanation:

$\sf = 20 \% \ of \ 860 \\\\= \frac{20}{100} * 860\\\\= 2 * 86\\\\= 172 \ points$

Since, Agnes scored 20 % fever than Amy.

So,

Agnes Score = Amy's Points - 20 % of Amy's Points

Agnes Score = 860 - 172

Agnes Score = 688 points

$\rule[225]{225}{2}$

Hope this helped!

There are 5 radar stations and the probability of a single radar station detecting an enemy plane is 0.55. What is the probabili

Lerok [7]

This is a binomial distribution with n = 5, p = 0.55, q = 1 - 0.55 = 0.45, x = 0, 1, 2, 3

P(x) = nCx p^x q^(n - x)
P(x ≤ 3) = 1 - P(x > 3) = 1 - [P(4) + P(5)]
P(4) = 5C4 x (0.55)^4 x (0.45) = 0.2059
P(5) = 5C5 x (0.55)^5 x 1 = 0.0503

P(x ≤ 3) = 1 - (0.2059 + 0.0503) = 1 - 0.2562 = 0.7438
