To solve this question, simply find the percent of loaves of bread to total items, by taking the first loaves of bread and dividing it by the total bakery items. In this case would be, 15 loaves/25 • 100% = 60 %. Do the same calculation for the second loaves of bread. 25 loaves/37 • 100% = 67.567 %.

Now take the difference between the 2 percentages to find the percent increase of loaves of bread, which would be 7.567 %, about 7.6%. Or as a whole number 8%.

The percent increase of the loaves of bread has been 8%.

Answer:

It removes the repeating part of the decimal from the equation.

Step-by-step explanation:

Described here is the process of converting the repeating decimal fraction into fraction in the form of p/q

1) --------------

x = 0.555555

2) --------------

10x = 5.555555

3) --------------

10 x - x = 5.555555 - 0.555555
9x = 5
x = 5/9

So the purpose of step 3 here is to remove the repeating part of the decimal from the equation

Correct option is the first one.

In any year, the weather can inflict storm damage to a home. From year to year, the damage is random. Let Y denote the dollar

krok68 [10]

Answer:

a. mean = 1000

standard deviation = 4358.9

b. expected value of average damage bar Y = 1000

probability bar y exceeds 2000 = 0.011

Step-by-step explanation:

we have p1 = 95%, y1 = 0, p2 = 5%, y2 = 20000

Mean = (0.95 * 0) + (0.05 * 20000)

= 1000

var(y) = E(y²) - E(Y)²

= we solve for E(y)²

= 0²*0.95 + 20000²*0.05

= 0 + 20000000

then the variance of y = 20000000 - 1000²

=20000000-1000000

= $19000000

standard deviation is the square root of variance

= √19000000

= 4358.9

a. Expected value of average is also the mean = 1000

b. we are to find probability that barY exceeds 2000

$z=\frac{2000-1000}{\sqrt{19000000/100} }$

= 1000/435.889

= 2.29

1-p(z≤2.29)

= 1 - 0.989

= 0.011

so the probability that barY exceeds 2000 is 0.011

Look at the picture.

a) 180° - 45° = 135°

b) Use trigonometric function

$\tan(\angle DBA)=\dfrac{45}{30}\\\\\tan(\angle DBA)=1.5\\\\m\angle DBA\approx56^o$

270° - 56° = 214°
