Answer: m = 3

Step-by-step explanation:

We can distribute both sides.

3*m + 3*7 = 6*m + 6*2

3m + 21 = 6m + 12

We can now combine like terms.

3m = 9

m = 3

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 105 and a standard deviation sigma equa
kondor19780726 [428]

Answer:   0.6827

Step-by-step explanation:

Given : Mean IQ score : \mu=105

Standard deviation : \sigma=15

We assume that adults have IQ scores that are normally distributed .

Let x be the random variable that represents the IQ score of adults .

z-score : z=\dfrac{x-\mu}{\sigma}

For x= 90

z=\dfrac{90-105}{15}\approx-1

For x= 120

z=\dfrac{120-105}{15}\approx1

By using the standard normal distribution table , we have

The p-value : P(90

P(z

Hence,  the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827

Class A has 25 pupils and class B has 28 pupils. Both classes sit the same maths test. The mean score for class A is 69. The mea
il63 [147K]

Answer:

13

Step-by-step explanation:

Mean would mean average, which in this case is \frac{x+y}{2}

so your equation would look like \frac{69+x}{2}=41

Next multiply both sides by to clear the fraction 2*(\frac{69+x}{2})

to get 69+x=89

Subtract 69 from both sides 69+x=82\\-69   -69

you get x = 13
