Answer:

x = 3

Step-by-step explanation:

we can use the Pythagorean theorem to solve this problem

x^2 + 4^2 = 5^2

x^2 + 16 = 25

x^2 = 9

x = +/- 3

we take only the positive value because a length can‘t be negative

x = 3

devlian [24]

Answer: 0.82

Step-by-step explanation:

We know that :

For any event A , the probability of not getting A is given by :-

P(not A)= 1- P(A)

Given : The probability that a student chosen at random from your class is a psychology major is P( psychology major) =0.18.

Then, the probability that a student chosen at random from your class is not a psychology major will be :

P(not psychology major)= 1 - P(psychology major)

= 1-0.18=0.82

Hence, the probability that a student chosen at random from your class is not a psychology major= 0.82

ss7ja [257]

Answer:

97m

From the image below we solve using pythagoras's theorem

x^2 = 72^2 + 65^2

x^2 = 5184 + 4225

x^2 = 9408

x = 97 m.

The ratio of girls to students at a middle school is 10 to 18. If there are 270 students at the school, how many are girls?

Stells [14]

A good way of doing this problem would be to use cross multiplication of ratios
<u /> $\frac{10 girls}{18 students} = \frac{X girls}{270 students}$

Then cross multiply

(10 girls)(270 students)=(X girls)(18 students)

2700=18x
150=x
