Convert 45% to a decimal by dividing it by 100. It becomes 0.45.

Multiply 0.45 onto 140.

You get 63. That’s how many eggs he sold.

<h3>A farmer had 140 eggs he sold 45% of them. </h3>

You have to find 45% of 140. First change 45% into a decimal to make it easier.

To change a percent into a decimal, move the decimal point 2 places to the left and remove the percent sign.

45 \% \rightarrow 0.45

Now multiply by 140

0.45 \times 140 = 63

The farmer sold 63 eggs

Kamila [148]

Answer:

15.9% of babies are born with birth weight under 6.3 pounds.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 6.8 pounds

Standard Deviation, σ = 0.5

We are given that the distribution of  birth weights is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(birth weight under 6.3 pounds)

P(x < 6.3)

P( x < 6.3) = P( z < \displaystyle\frac{6.3 - 6.8}{0.5}) = P(z < -1)

Calculation the value from standard normal z table, we have,  

P(x < -1) = 0.159 = 15.9\%

15.9% of babies are born with birth weight under 6.3 pounds.

Need help with this problem
alexandr1967 [171]

Answer:

x = 10

Step-by-step explanation:

Since the triangles are similar the ratios of corresponding sides are equal

\frac{20}{20+8} = \frac{3x}{4x+2}, that is

\frac{20}{28} = \frac{3x}{4x+2} ( cross- multiply )

20(4x + 2) = 84x

80x + 40 = 84x ( subtract 80x from both sides )

40 = 4x ( divide both sides by 4 )

x = 10

If you don't want to, thwn do this

Preimage(0-4,1+3),(4-4,6+3),(-5-4,-1+3)

Since we are finding z, we only use the final cordinates

z'=(-9,2)
