Step-by-step explanation:

1) Rewrite \frac{3}{8} as a percent.

Multiply the number by 100,

\frac{3}{8}\times 100=37.5\%

2) Rewrite 0.82 to a fraction in simplest form.

0.82=\frac{82}{100}=\frac{41}{50}

3) Rewrite \frac{5}{6} as a decimal.

\frac{5}{6}=0.8\bar{3}

4) Rewrite 0.04 as a percent.

Multiply the number by 100,

0.04\times 100=4\%

5) Rewrite 20% as a fraction in simplest form.

20\%=\frac{20}{100}=\frac{1}{5}

6) Rewrite 152% as a decimal.

152\%=\frac{152}{100}=1.52

7) Order from least to greatest: 1/4, 32%, 0.4

Write in same form,

0.25,0.32,0.4

0.25<0.32<0.4

The order from least to greatest is 1/4, 32%, 0.4.

8) Order from least to greatest: 15%,0.015,1/5

Write in same form,

0.5,0.015,0.2

0.015<0.2<0.5

The order from least to greatest is 0.015,1/5, 15%.

9) Order from greatest to least: 1.62, 16.2%, 15/20

Write in same form,

1.62,0.162,0.75

0.162<0.75<1.62

The order from greatest to least is 1.62,15/20, 16.2%

10) Order from greatest to least: 17/20, 75%, 0.8

Write in same form,

0.85,0.75,0.8

0.8<0.75<0.85

The order from greatest to least is 17/20,75%,0.8.

11) Order from least to greatest: 0.14,1/8,1.9%

Write in same form,

0.14,0.125,0.019

0.019<0.125<0.140

The order from least to greatest is 1.9%,1/8,0.14

12) Order from greatest to least: 2/3,66%,0.67

Write in same form,

0.66..,0.66,0.67

0.67<0.66...<0.66

The order from greatest to least is 66%, 2/3, 0.67.

A coin flipped 14 times and it comes up heads 10 times what is the experimental probability of the coin’s coming up heads ?
Gekata [30.6K]

The answer is B.

If a coin is flipped 14 times and lands on heads 10 times the fraction would equal to 10/14.

10/14 simplifies to 5/7.

A company makes rubber rafts. 12% of them develop cracks within the first month of operation. 27 new rafts are randomly sampled
rewona [7]

The probability that the number of tested rafts that develop cracks is no more than 3 is <u>.00006</u>.

The true proportion, p for the population is given to 0.12.

Thus, the mean, μ, for the sample = np = 27*0.12 = 3.24.

The sample size, n, given to us is 27.

Thus, the standard deviation, s, for the sample can be calculated using the formula, s = √{p(1 - p)}/n.

s = √{0.12(1 - 0.12)}/27 = √0.003911 = 0.0625389.

We are asked to calculate the probability that the number of tested rafts that develop cracks is no more than 3, that is, we need to calculate P(X ≤3).

P(X ≤ 3)

= P(Z ≤ {(3 - 3.24)/0.0625389) {Using the formula z = (x - μ)/s}

= P(Z ≤ -3.8376114706)

= .00006 {From table}.

Thus, the probability that the number of tested rafts that develop cracks is no more than 3 is <u>.00006</u>.

This is the graph of y = sin(x). Does anyone know the second part?
Alborosie

Answer:

The resulting graph is y = 5\cdot \sin x.

Step-by-step explanation:

The resulting function is of the form:

y = A\cdot \sin x + k

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

A - Amplitude, dimensionless.

k - Midpoint value, dimensionless.

The sine function is bounded, between -1 and 1, and must be multiplied by a stretch factor. That is: A > 0. According to the graph, the function is bounded between 5 (y_{max}) and -5 (y_{min}), and the midpoint value (k) is 0. The amplitude is determined by the following calculation:

A = \frac{y_{max}-y_{min}}{2}

If y_{min} = -5 and y_{max} = 5, then:

A = 5

The resulting graph is y = 5\cdot \sin x.

Your averages and values are the following:
ioda

Answer: You need a grade of 78 on the final exam to earn a final grade average of at least 87 in each grading system.

Step-by-step explanation:

(85 + 90 + 95 + x)÷ 4 =87

Simplify:

(270 + x) ÷ 4 = 87

Rearrange:

(x + 270) ÷ 4 = 87

Multiply terms to Reduce:

4((x + 270) ÷ 4) = 4 * 87

Cancel Multiplied terms in Denominator:

x + 270 = 4 * 87

Multiply:

x + 270 = 348

Subtract 270 on both sides of the equation:

x + 270 - 270 = 348 - 270

Simplify:

x = 78
