Answer:

see explanation

Step-by-step explanation:

Note that

sin60° = $\frac{\sqrt{3} }{2}$ , cos60° = $\frac{1}{2}$

Using trig. ratios in the right triangle

sin60° = $\frac{opp}{hyp}$ = $\frac{x}{18}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2x = 18 $\sqrt{3}$ ( divide both sides by 2)

x = $\frac{18\sqrt{3} }{2}$ = 9 $\sqrt{3}$

-----------------------------------------------------------------------------

cos60° = $\frac{adj}{hyp}$ = $\frac{y}{18}$ = $\frac{1}{2}$ ( cross- multiply )

2y = 18 ( divide both sides by 2 )

y = 9

Matthew completed 5/8 of his workday. What decimal would also describe the portion of the workday he has finished? How can you u

Natalija [7]

Answer:

a)D= 0.625 Decimal that describes the portion of the workday he has finished

b)P= D*100= 0.625*100=62.5%

P: percentaje

D: Decimal

Step-by-step explanation:

Nomenclature

F: fraction of daily workday

D: decimal of daily workday

P: percentage of daily workday

Formulas

F= a/b

D= a÷b

P= D*100

Problem development

We have:

F = 5/8, then:

D= 5÷8= 0.625

To obtain the percentage of the workday that Matew has completed, we multiply the decimal x 100

P= 0.625*100=62.5%

Equation: w = 112 + 8t Which input results in an output of 176? What is the output in the ordered pair (4, 144)?

Grace [21]

Answer:

Step-by-step explanation:

Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."

So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.

w = 112 +8t

176 = 112 + 8t

64 = 8t . . . . . . . subtract 112

8 = t . . . . . . . . . divide by 8

The input for an output of 176 is 8.

Ordered pairs are always written as ...

(input, output)

So, (4, 144) means the output is 144 for an input of 4.

A bakery wants to determine how many trays of doughnuts it should prepare each day. Demand is normal with a mean of 5 trays and

Alexeev081 [22]

Answer:

4 trays should he prepared, if the owner wants a service level of at least 95%.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 5

Standard Deviation, σ = 1

We are given that the distribution of demand score is a bell shaped distribution that is a normal distribution.

Formula:

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

P(X > x) = 0.95

We have to find the value of x such that the probability is 0.95

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 5}{1})=0.95$

$= 1 -P( z \leq \displaystyle\frac{x - 5}{1})=0.95$

$=P( z \leq \displaystyle\frac{x - 5}{1})=0.05$

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

$\displaystyle\frac{x - 5}{1} = -1.645\\x = 3.355 \approx 4$

Hence, 4 trays should he prepared, if the owner wants a service level of at least 95%.
