3 0

Answer:

The first step is to slove the numbers in the brackets

Step-by-step explanation:

[(x+7) x -2] / 4 = 7

-2(x+7) / 4 = 7

-2x-14 / 4 = 7

-2x-14 = 28

-2x = 42

x = -21

Suppose a normal distribution has a mean of 62 and a standard deviation of4. What is the probability that a data value is betwee
saw5 [17]

SOLUTION

From the given data the mean is 62 and standard deviation is 4

It is required to find the probability that a data value is between 57 and 62

That is:

P(57\lt x\lt65)

The z scores is calculated using:

z=\frac{x-\mu}{\sigma}

Using the x values it follows:

z=\frac{57-62}{4}=-1.25

Also,

z=\frac{65-62}{4}=0.75

Thus the required probability is:

P(-1.25The proability is:[tex]P(-1.25This can be expressed as percentage as:[tex]P(-1.25\lt z\lt0.75)=66.8\%

Therefore the correct option is C

solve systems of equation. equation number 1: 9 x squared + 4 y squared equals 144. equation 2: x squared plus y squared equals
grigory [225]
9x^{2} + 4y^{2} =144
x^{2} + y^{2}=24

9x^{2} + 4y^{2} =144
 4x^{2} + 4y^{2}=96
by the difference 
5x^{2}=48
so x=\sqrt{\frac{48}{5}} or x=-\sqrt{\frac{48}{5}}
and y^{2}=24-\frac{48}{5}
then y=\sqrt{\frac{72}{5}} or -\sqrt{\frac{48}{5}}
