Brayden read the thermometer outside his window. It said that it was 68°F. What is the temperature in degrees Celsius? Use the f

ormula C = 5/9 (F – 32) where C represents the temperature in degrees Celsius and F represents the temperature in degrees Fahrenheit.

While Preparing For A Morning Conference, Principal Corsetti Is Laying Out 8 Dozen Bagels On Square Plates. Each Plate Can Hold

USPshnik [31]

We have 8 dozen bagels, or 8*12=96 bagels. Each plate can hold 14 bagels, so we have enough bagels to fill 96/14=about 6.86 plates. However, we cannot have a fraction of a plate, so we round up to have a total of seven plates. To fill all seven plates fully, 7*14=98 bagels would be needed, which is two more than we have.

To summarize, Mr. Corsetti has seven plates of bagels, and would need two more bagels to fill the last one up.

shari’s class is making team pennants for an upcoming field day.they cut the pennants out of a large sheet of paper in the patte

Svetllana [295]

In this item, it is assumed that since the pattern is cut out of the paper which is usually a rectangle then, the shape of the pattern is also rectangle. The perimeter of the rectangle is,

P = 2L + 2W

The area is equal to,
Area = L x W

If we assume that length and width are equal, in order to maximize the space.
1600 cm² = L x L

The value of L from the equation is 40 cm.

Answer:

$f^{-1}(x)=4x+20$

Step-by-step explanation:

<u>Given</u>

<u /> $f(x)=\frac{x}{4}-5\\ \\y=\frac{x}{4}-5$

<u>Swap x and y and solve for y</u>

<u /> $y=\frac{x}{4}-5\\ \\x=\frac{y}{4}-5\\ \\x+5=\frac{y}{4}\\ \\4(x+5)=y\\\\y=4x+20$

<u>Final answer</u>

<u /> $f^{-1}(x)=4x+20$

Keep in mind that we need to swap the variables because a function and its inverse are symmetrical about the line y=x. See the graph below.

8. A company makes electronic components for TV's. 95% pass final inspection (and 5% fail and need to be fixed). 120 components

Taya2010 [7]

Using the binomial distribution, it is found that the variance of the number that pass inspection in one day is 5.7.

For each component, there are only two possible outcomes, either it passes inspection, or it does not. The probability of a component passing inspections is independent of any other component, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

Probability of <u>exactly x successes on n repeated trials, with p probability</u>, and has variance given by:

$V(X) = np(1 - p)$

In this problem:

95% pass final inspection, hence $p = 0.95$

120 components are inspected in one day, hence $n = 120$ .

The variance is given by:

$V(X) = np(1 - p) = 120(0.95)(0.05) = 5.7$

The variance of the number that pass inspection in one day is 5.7.
