F(2)=-5x+6 find value

Answers

Answer:

F(x) = 16

Step-by-step explanation:

F = 2. We find the value of -5x by inputting the value of the function into the x value.

F(x) = -5(2) + 6

F(x) = 10 + 6

F(x) = 16

A circle's circumference is approximately 88 cm. Estimate the diameter, rounding to the nearest WHOLE number. (don't forget your units and use 3.14 if you need to use )

Answers

Answer:

diameter = 28 cm

Step-by-step explanation:

circumference = 2πr

88 cm = 2 * 3.14.*r. ( π = 3.14 )

r = ( 88)/(3.14*2)

r = 14 cm

diameter = 2 * radius

diameter = 2 * 14 cm

diameter = 28 cm

Answer:

28 cm

Step-by-step explanation:

Circumference formula:

C = πd

Substitute values of circumference and the π to find the diameter:

d = C/πd = 88/3.14 = 28 cm (rounded)

Answer: (-2,1) is the coordinate if rotated 270 degrees from origin.

Step-by-step explanation:

Answer:

A' = (-1,2)

Step-by-step explanation:

The other person is in fact incorrect. The reason why he/she is incorrect is because, it says "rotation about the origin." which means that is flips around the middle. 90 degree rotation would be (1,-2), a 180 degree rotation would be (-2,1), a 270 rotation would be (-1,2).

Therefore, your answer would be A' = (-1, 2)

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply A. 160 shirts cost $20
B. 20 shirts cost $160
C. 20,160 shirts cost money
D. The total cost of shirts is 20,160

Answers

Answer:

option B is correct option.

Step-by-step explanation:

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply

Looking at the graph we come to know that 20 shirts cost $160 because x -axis represent number of shirts and y-axis represent Total Cost

So, the point(20,160) means x = 20 and y=160

We have 20 shirts and the cost is $160

So, option B is correct option.

47.5% of children say that chocolate chip cookie is their favorite kind of cookie. If you randomly select 12 children find the probability that: a) at least 10 of them say that chocolate chip cookie is their favorite cookie. B) four of them say that chocolate chip cookie is their favorite cookie. C) Find the mean and standard deviation for this sample.

Answers

Answer: a) 0.0125 b) 0.1454 c) Mean = 5.7, standard deviation = 1.73

Step-by-step explanation:

Let x = Number of children say that chocolate chip cookie is their favorite kind of cookie.

x follows binomial distribution.

Binomila distribution formula:

[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex] , where p = probability in each trial, n = sample size, x= number of successes

Sample size : n= 12, p=0.475

[tex]P(x\geg10)= P(x=10)+P(x=11)+P(x=12)\\\\=\ ^{12}C_{10}(0.475)^{10}(1-0.475)^{2}+^{12}C_{11}(0.475)^{11}(1-0.475)^{1}+^{12}C_{12}(0.475)^{12}(1-0.475)^{0}\\\\=\dfrac{12!}{2!10!}(0.475)^{10}(0.525)^{2}+(12)(0.475)^{11}(0.525)^{1}+(1)(0.475)^{12}\\\\\approx0.0125[/tex]

[tex]P(x=4)= ^{12}C_{4}(0.475)^4(0.525)^{8}\\\\=\dfrac{12!}{4!8!}(0.000293798)\\\\=0.1454[/tex]

c) Mean = np

= (12)(0.475) =5.7

Standard deviation = [tex]\sqrt{np(1-p)}[/tex]

[tex]=\sqrt{12\times0.475\times0.525}\\\\=\sqrt{2.9925}\approx1.73[/tex]

In a group of 60 students, 15 liked maths only, 20 liked science only and 5 did not liked any of two subjects. How many of them liked at least one subject?

Answers

Answer:

Step-by-step explanation:

Given

n (A) = 15

n (B) = 20

Students who do not like any subject = 5

Hence, number of students who would like either both or either of the two subjects = 60-5 = 55

n (A or B) = n (A) + n (B) - n (A and B)

Number of students linking both the subjects

55 - 15-20

= 55-35 = 20

Number of students linking only one subject = 60-20-5 = 35

Read the following article.The Automobile and Its ImpactFor most Americans, not a day goes by that they are not affected by cars. The automobile has had more of an impact on American life than any other mode of transportation. The automobile has changed where people live, how people work, and how people view one another.In the early 20th century, people who worked in cities had to live in those cities. People lived in crowded apartments with very little room for their families. When the automobile became available to the masses, people were able to move outside of cities to live. The automobile is what led to the growth and development of the suburbs. People began building homes on the outskirts of cities. Soon these places became communities with roads, police stations, and restaurants. This helped create jobs in those areas. People could choose whether they wanted to drive their car to work in the city or closer to home. Either way, this choice and way of life would not be possible without the automobile.Cities were not the only areas affected by cars. The invention of the automobile helped increase farm production and distribution. Before the invention of the car, farmers used horses to travel. They were limited to only traveling 1520 miles. Now, with cars and later trucks, farmers could deliver their products many miles away. This meant that more people could buy their products, and the farmer could earn more money. This also meant that people could enjoy produce that was not locally grown. Cars did not only have positive impacts on American society. The invention of the car created a new class system for Americans. In the early 20th century, only the wealthy were able to own cars. Over time, cars became status symbols. Some cars were created simply as a symbol of wealth and class. That is still the case today. Cars have also created more pollution. The gasoline that cars need to run has negatively affected the air. The more cars there are, the more polluted the air becomes.The invention of the car has changed how people live in both positive and negative ways. This cannot be said for any other mode of transportation. Although ships and planes have made travel more convenient, they have not impacted a person's everyday life in the same way as cars.What evidence does the author use to support the idea that cars increased farm distribution? Farmers could now farm different types of produce. Farmers could now live in cities and work in farms. Farmers could now travel more than 1520 miles a day. People who lived in suburbs could now start a farm.
