Answer: ⇒ $-\frac{3}{20}$

______________________________________________________

Step-by-step explanation:

First you had to remove parenthesis first.

$\frac{7}{10}- \frac{17}{20}$

$=\frac{14}{20}-\frac{17}{20}$

Since the denominator are equal, and then you had to combine by the fraction.

$\frac{14-17}{20}$

Subtract by the numbers.

$\frac{-3}{20}$

Apply the fraction rule.

$=-\frac{3}{20}$

What is the Y- intercept of the graph of the line given by equation 3y+4x=15?

KATRIN_1 [288]

Yint is where the line crosses the y axis or where x=0
set x=0

3y+4x=15
x=0
3y+4(0)=15
3y+0=15
3y=15
divide by 3
y=5

yint is (0,5) or at y=5

In Texas, 30% of parolees from prison return to prison within 3 years. Suppose 15 prisoners are released from a Texas prison on

LUCKY_DIMON [66]

Answer:

N = 15 ; P = 0.3

Step-by-step explanation:

According to the question, the data provided in the question is as follows

The percentage of parolees from prison return to prison = 30%

Number of years = 3 years

Number of prisoners released from a Texas prision is 15

Based on the above information, the value of the parameters for the binomial random variable X is

N = 15 = number of prisoners

And, the P = Percentage = 30% = 0.3

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 $y = 5\cdot \sin x$ .
