A company manufactures a large number of rods. The lengths of the rods are normally distributed with a mean length of 4.4 inches

Elza [17]

Answer:

0.78814

Step-by-step explanation:

We solve using z score

z = (x-μ)/σ, where

x is the raw score = 4.0 inches

μ is the population mean = 4.4 inches

σ is the population standard deviation = 0.5 inches

z = 4.0 - 4.4/0.5

z = -0.8

Probability value from Z-Table:

P(x<4.0) = 0.21186

P(x>4.0) = 1 - P(x<4.0)

= 1 - 2.1186

= 0.78814

The probability that the rod you chose will be greater than 4.0 inches is 0.78814.

The ratio of boys to girls in a choir is 3 to 6. There are 30 girls in the choir.

agasfer [191]

Answer:

45 members are in the choir.

Step-by-step explanation:

Set up an equation:

Variable x = boys

3/6 = x/30

Cross multiply:

3 × 30 = 6 × x

90 = 6x

Divide both sides by 6:

15 = x

There are 15 boys.

To find the number of members in the choir, add the number of boys and girls:

30 + 15 = 45

Need someone with a big brain to help lol<br> Solve for x

AfilCa [17]

Answer:

x=4

Step-by-step explanation:

Hey there!

I am going to use this image as an example so you can understand the formula

The formula for problems like these is

B(BA)=D(DC)

So all we have to do is plug in the numeric values

so now we have 5(5+x+3)=6(6+x)

now we just solve for x

5(5+x+3)=6(6+x)

step 1 distribute the 5 to what is in the parenthesis (5, x and 3)

5x5=25

5*x=5x

5x3=15

so now we have

25+5x+15=6(6+x)

step 2 distribute the 6 to what is in the parenthesis (6 and x)

6x6=36

6*x=6x

now we have

25+5x+15=6x=36

step 3 combine like terms, the only like terms are 25 and 15

15+25=40

now we have

40+5x=6x+36

step 4 subtract 5x from each side

5x-5x cancels out

6x-5x=x

now we have

40=x+36

step 5 subtract 36 from each side

40-36=4

36-36 cancels out

now we have

x=4 so we can conclude that x=4

hope this helps :)
