Four sisters buy a total of 3 1/2 feet of ribbon . The sisters want to share the ribbon equally how many feet of ribbon will each sister receive? 3/8 ft , 1/4 ft,1/2 ft, 7/8 ft

Answers

Answer:

each sister receives (7/8) ft of ribbon

Step-by-step explanation:

Let's start by writing the total amount of ribbon in fraction form:

3  1/2  = 3 + (1/2) = (7/2)

Now, we need to perform the division: (7/2) divided by 4

in order to find how much ribbon each sister gets. We convert the division of fractions into a product to make the operation simpler. This is done by using the reciprocal of the number that divides (in our case the reciprocal of "4" which is: (1/4):

(7/2) divided 4 = (7/2) x (1/4)

and we multiply the fractions obtaining:

(7/8)

So, each sister receives (7/8) ft of ribbon

Write an equation for the parent function y = x^ 2 stretched by a factor of 6 and shifted down 4 units?

Answers

Answer:

 

Translations

y = f (x) + k up k units

y = f (x) - k down k units

y = f (x + h) left h units

y = f (x - h) right h units

Stretches/Shrinks

y = m·f (x) stretch vertically by a factor of m

y = ·f (x) shrink vertically by a factor of m (stretch by  

y = f (x) stretch horizonally by a factor of n

y = f (nx) shrink horizontally by a factor of n (stretch by )

Reflections

y = - f (x) reflect over x-axis (over line y = 0)

y = f (- x) reflect over y-axis (over line x = 0)

x = f (y) reflect over line y = x

In a particular town, 20% of the homes have monitored security systems. If an alarm is triggered, the security system company will contact the local police to alert them of the alarm. Of all the alarm calls that the local police receive, they only have the manpower to answer 30% of the calls. Suppose we randomly sample one home that was broken into over the last month from this town. What is the probability that this home has a monitored security system and that the police answered the alarm call?

Answers

Answer:

The probability to have both = 0.06

Step-by-step explanation:

Given:

Security system home = 20% = 0.2

Manpower for security calls = 30% = 0.3

Find:

The probability to have both

Computation:

The probability to have both = P(Security system home) × P(Manpower for security calls)

The probability to have both = (0.2)(0.3)

The probability to have both = 0.06

a. What is the sample here? And what is the population? (1pts)

b. Is this a descriptive or a statistical inference? Why?

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Selected = 1000[/tex]

(a): Samples & Population

The samples are the selected data from an overall population.

In this case, the samples are the selected citizens in Seattle, Washington

Since 1000 citizens were selected

[tex]Samples = 1000[/tex]

Also, since the samples were selected from citizens in Seattle, Washington

Then the population are the citizens in Seattle, Washington

(b): Type of Statistics

From the question, we observe that the data was used to conclude that between 55% and 59% of the population would pay higher price.

This type of statistics is referred to as the inferential statistics.

If random variable X has a binomial distribution with n=15 and P(success) =p= 0.6, find the mean of X. That is, find E(X). Round to the whole number. Do not use decimals. Answer:

Answers

Answer:

9

Step-by-step explanation:

E(X) = np

E(X) = (15) (0.6)

E(X) = 9

The mean of the X is 9.

What is the mean of the binomial distribution?

The mean of a binomial distribution is the expected value (long-run average) of the number of successes in the given number of trials.

Formula for calculating mean of binomial distribution

[tex]\mu_{x} = n.p[/tex]

where,

[tex]\mu_{x}[/tex] is the mean of the binomial distribution

n is the number of trials

and, p is the probability of success

According to the given question.

We have

Number of trials, n = 15

Probability of success, p = 0.6

Therefore, the mean of X is given by

[tex]E(X) = 15(0.6)[/tex]

⇒ [tex]E(X) = 9[/tex]

Hence, the mean of the X is 9.

Find x so the distance between the points (x,2) and (-1,-2) is [tex]2\sqrt{5}[/tex]

x =_____ , ______

Answers

Answer:

x = -5 , 3

Step-by-step explanation:

(x₁ , y₁) = (-1, -2)    & (x₂, y₂) = (x , 2)

[tex]Distance =\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\\\\sqrt{(x - [-1])^{2}+(2-[-2])^{2}}=2\sqrt{5}\\\\\sqrt{(x+1)^{2}+(2+2)^{2}}=2\sqrt{5}\\\\\sqrt{(x)^{2}+2x+1+(4)^{2}}=2\sqrt{5}\\\\\sqrt{x^{2}+2x+1+4}=2\sqrt{5}\\\\\sqrt{x^{2}+2x+5}=2\sqrt{5}[/tex]

Take square both sides,

x² + 2x + 5 = (2)²(√5)²               {(√5)² = √5*√5 = 5 }

x² + 2x +5 = 4 * 5

x² + 2x + 5 = 20

x² + 2x + 5 - 20 = 0

x² + 2x  -15 = 0

x² + 5x - 3x  - 5*3 = 0

x(x + 5) -3(x + 5)=0

(x + 5)(x - 3) = 0

x + 5 = 0     ; x - 3 = 0

x = -5        ;    x = 3

x = -5 , 3
