One hundred families each have $2$ fish. Each fish has either one stripe or two stripes. In total, there are $273$ stripes. How many one-striped fish are there in total?

Answers

Let x be the number of one-striped fish and y the number of two-striped fish.

100 families each have 2 fish, so there are a total of 200 fish:

x + y = 200

x one-striped fish carry a total of x stripes, while y two-striped fish carry a total of 2y stripes. There are 273 stripes overall, so

x + 2y = 273

Solve for x and y. Subtracting the first equation from the second eliminates x :

(x + 2y) - (x + y) = 273 - 200   ==>   y = 73

Then

x + 73 = 200   ==>   x = 127

Translate the sentence into a sentence Six more than the quotient of a number and 4 is equal to 8

Answers

Answer:

[tex] \frac {x}{3} + 6 = 8 [/tex]

Step-by-step explanation:

Let the unknown number be x.

Quotient simply means to divide a number by another number without any remainder.

For example, a quotient of 2 simply means that a number divided by 5 would have a value that is equal to 2 without any remainder; [tex] \frac {10}{5} = 2[/tex]

Hence, translating the word problem in this scenario into an algebraic expression, we have;

[tex] \frac {x}{3} + 6 = 8 [/tex]

Simplifying further, we have;

[tex] \frac {x}{3} = 8 - 6 [/tex]

[tex] \frac {x}{3} = 2 [/tex]

Cross-multiplying, we have;

x = 3 * 2

x = 6

The area of square A is 40ft^2 . The area of square B is 250% of the area of square A. What is the length of one side of square B?

Answers

Answer:

Step-by-step explanation:

We are given the area of square A as 40 ft². Then we are told that the area of square B is 250% of A's area. The equation in words that we are going to be using is:

Area of square B = 2.5 × Area of square A where the word "is" is replaced by an equals sign, and the word "of" is replaced by a multiplication sign. We know that the area of A is 40, so:

Area of square B = 2.5(40) and

Area of square B = 100 ft²

The area formula for a square is A = s², so if the Area is 100:

100 = s² so

s = 10ft

According to a study done by a university student, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267 Suppose you sit on a bench in a mall and observe people's habits as they sneeze

(a) What is the probability that among 18 randomly observed individuals exactly 6 do not cover their mouth when sneezing?

Answer:

[tex]P(X=6)=(0.162)[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size [tex]n=18[/tex]

No. that do not cover their mouth when sneezing [tex]x=6[/tex]

Generally the equation for The Binomial distribution is mathematically given by

Therefore

[tex]P(X=x)=(18..x)(0.267)^x(1-0.267)^{18-x}[/tex]

Products come off an assembly line at the rate of several hundred per hour. It is desired to sample 10% of them to check whether they meet quality standards. Describe a sampling method that would be appropriate in this situation. Explain your reasoning.

Answers

Answer:

10% of the hundreds of products will be sampled, so the most effective sample method would be systematic sampling, checking every 10th product, which would avoid sources of bias such as missing a region of production where there could be some problems.

Step-by-step explanation:

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this case:

10% of the hundreds of products will be sampled, so the most effective sample method would be systematic sampling, checking every 10th product, which would avoid sources of bias such as missing a region of production where there could be some problems.

Answer:

2/83/5

Step-by-step explanation:

1. The denominator of a fraction indicates how many (equal) pieces a quantity is divided into. When that quantity is 1 cake, and it is divided into 8 equal pieces, each piece is 1/8 of the cake, and there are 8 pieces, or 8/8 of the cake altogether. 8/8 = 1 entire.

When 2/8 of the cake is eaten, there are 8-2 = 6 pieces left, or 6/8 of the cake remains.

When an additional 4/8 of the cake is eaten, there are 6-4 = 2 pieces left, or 2/8 of the cake remains.

__

The fraction 2/8 can be written as the product of fractions ...

  [tex]\dfrac{2}{8}=\dfrac{1\cdot2}{4\cdot2}=\dfrac{1}{4}\cdot\dfrac{2}{2}[/tex]

We know that 2/2 = 1, and anything times 1 is that same thing, so the fraction 2/8 can be "reduced" to its equivalent, 1/4.

  [tex]\dfrac{2}{8}=\dfrac{1}{4}\cdot1=\dfrac{1}{4}[/tex]

As far as we can tell, this question does not ask you to reduce the fraction. Since we're counting 1/8 cake slices, and there are 2 remaining, it is reasonable to leave the fraction as 2/8.

____

2. The given fractions are 1/5 pound, so it is reasonable to think of the whole weight of the 1-pound box as 5/5 pound. Two parts are 1/5 pound each, so the part remaining after considering those is ...

  5/5 - 1/5 - 1/5 = (5 -1 -1)/5 = 3/5

The third item in the box is 3/5 pound.

In a certain armithmetic sequence , if -4 is the first term , and 10 is the third term, which term is 157?

Answers

Answer:

157 is the 24th term.

Step-by-step explanation:

We are given that in an arithmetic sequence, -4 is the first term and 10 is the third term. And we want to find the term number of 157.

Recall that the direct formula for an arithmetic sequence is given by:

[tex]\displaystyle x_n=a+d(n-1)[/tex]

Where n is the nth term, a is the initial term, and d is the common difference.

We know that the initial term a is -4. Hence:

[tex]x_n= -4 + d(n-1)[/tex]

Since 10 is the third term, n = 3:

[tex]\displaystyle x_{3}=10=-4+d(3-1)[/tex]

Solve for the common difference:

[tex]14=2d\Rightarrow d=7[/tex]

Hence, our direct formula is:

[tex]\displaystyle x_n=-4+7(n-1)[/tex]

To find the term number of 157, let 157 equal xₙ and solve for n. Hence:

[tex]\displaystyle (157)=-4+7(n-1)[/tex]

Therefore:

[tex]\displaystyle \begin{aligned} 161 &= 7(n-1) \\ 23 & = n-1 \\ n &= 24\end{aligned}[/tex]

157 is the 24th term.

A research center conducted a telephone survey of 2,000 adults to learn about the major economic concerns for the future.

(a) What is the point estimate of the population proportion of adults who think the future health of Social Security is a major economic concern

Answers

Answer:

0.81

Step-by-step explanation:

Find the point estimate by dividing the number of respondents that thought it was a major economic concern by the total number of people in the survey:

1,620/2,000

= 0.81

So, the point estimate is 0.81

evaluate the integral x^3 (x 4 −8)^44 dx by making the substitution u = x^4 - 8

Answers

Answer:

(x^4-8)^45 /180 +c

Step-by-step explanation:

If u=x^4-8, then du=(4x^3-0)dx or du=4x^3 dx by power and constant rule.

If du=4x^3 dx, then du/4=x^3 dx. I just divided both sides by 4.

Now we are ready to make substitutions into our integral.

Int(x^3 (x^4-8)^44 dx)

Int(((x^4-8)^44 x^3 dx)

Int(u^44 du/4)

1/4 Int(u^44 dul

1/4 × (u^45 / 45 )+c

Put back in terms of x:

1/4 × (x^4-8)^45/45 +c

We could multiply those fractions

(x^4-8)^45 /180 +c

The warm air of the Pacific Ocean brings precipitation to the western part of the park. In contrast, the Arctic Ocean's cold air makes the northeastern side drier. The air from the Pacific Ocean and Arctic Ocean can collide on the Continental Divide. A blizzard can develop. As a result, these mountains can have 100 inches of annual snowfall.
