the answer choices are A) A B) B C) C D) D

Answer:

B

Step-by-step explanation:

its 60°

thank me later

Answer:

B

Step-by-step explanation:

Triangles have angle totals adding to 180. You already have 120 so the other must be 60.

Answer:

84.

Step-by-step explanation:

The 8 is in the 10s place and 4 is lower than 5. anything lower than 5 should be rounded down.

Answer:

A sample size of 1380 should be obtained.

Step-by-step explanation:

Minimum sample size:

The minimum sample size is of:

[tex]n = (\frac{z}{E})^2(p_1(1-p_1) + p_2(1-p_2))[/tex]

In which z is the critical value, related to the confidence level, E is the desired margin of error, [tex]p_1[/tex] and [tex]p_2[/tex] are the proportions.

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

Estimates of 22.6​% male and 18.1​% female from a previous​ year

This means that [tex]p_1 = 0.226, p_2 = 0.181[/tex].

Within 3 percentage points, minimum sample size:

This is n for which [tex]E = 0.03[/tex]. So

[tex]n = (\frac{z}{E})^2(p_1(1-p_1) + p_2(1-p_2))[/tex]

[tex]n = (\frac{1.96}{0.03})^2(0.226*0.774 + 0.181*0.819)[/tex]

[tex]n = 1379.4[/tex]

Rounding up:

A sample size of 1380 should be obtained.

Answer:

830 cents

5n + p

Step-by-step explanation:

Given that :

Number of nickels = 140

Number of pennies = 130

Total coins :

140 nickels + 130 pennies

1 nickel = 5 cent

1 penny = 1 cent

Hence,

140(5) + 130(1)

700 + 130

= 830 cents in total

If :

number of nickels = n

Number of pennies = p

Tot coins :

5n + 1p

5n + p

Step-by-step explanation:

<=> -2/5 (x+2)(x-5)

-2/5 (x²-3x-10)

-2/5 x² + 6/5 +4

Answer:

413 people should be expected to go to Fiction and Literature

Step-by-step explanation:

Proportion of people who went to Fictions and Literature on Saturday:

342 out of 467 + 433 + 343 = 1243

The proportion is:

342/1243 = 0.275

On Sunday:

Based on Saturday, so 0.275 out of 1500(number of visitors on Sunday).

0.275*1500 = 412.5

Rounding to the nearest whole number:

413 people should be expected to go to Fiction and Literature

Complete question :

When Hiroto is writing, there is 0.92 probability that there will be no spelling mistakes on a page. One day, Hiroto writes an essay that is 11 pages long.

Assuming that Hiroto is equally likely to have a spelling mistake on each of the 11 pages, what is the probability that he will have a spelling mistake on at least one of the pages?

Answer:

0.60

Step-by-step explanation:

The question meets the requirement for a binomial probability distribution :

Recall:

P(x = x) = nCx * p^x * q^(n-x)

Given :

Probability of making a spelling mistake = 1 - p(not making) = 1 - 0.92 = 0.08

Hence,

p = 0.08 ; q = 0.92

n = 11

P(x ≥ 1) = 1 - p(x = 0)

P(x = 0) = 11C0 * 0.08^0 * 0.92^11

P(x = 0) = 1 * 1 * 0.3996373778857415671808

P(x = 0) = 0.399

P(x ≥ 1) = 1 - p(x = 0)

P(x ≥ 1) = 1 - 0.399

P(x ≥ 1) = 0.601

P(x ≥ 1) = 0.60

Answer:

Therfore, the value of x is 1/2.

Step-by-step explanation:

5(2x + 3) = 20

10x + 15 = 20

10x = 20-15

10x = 5

x = 5/10

x = 1/2

Answer:

0.5

Step-by-step explanation:

5(2x + 3) =20

10x + 15 = 20

10x = 20-15

10x =5

x= 1/2

Answer:

A) (1,9), 3/2

Step-by-step explanation:

Equation of a line:

The equation of a line, in point-slope format, is given by:

[tex]y - y_0 = m(x - x_0)[/tex]

y - 9 = 3/2(x - 1)

Comparing with above, we have that:

The point is [tex](x_0, y_0) = (1, 9)[/tex] and the slope is [tex]m = \frac{3}{2}[/tex]. The correct answer is given by option A.

Answer:

11 is the answer

Step-by-step explanation:

Restating into scientific notation means, making a super big or a super small number, more understandable to read. For example,

5,972,000,000,000,000,000,000,000.0012 is a big number. I don't think you even tried to read that. There is a solution to this problem. This is the exact number but in scientific notation. 5.972 × 10^24. Isn't that easier to read?

the discount price was 29.2

step by step 146 minus 20% = 116.8 116.8 + 4% =121.472 the sales tax added 4.672$ to the total amount and the discount price removed 29.2 of the required pay

Answer:

Expected value: $5.20

Answer:

5/8

Step-by-step explanation:

There are two numbers from one to eight that are less than three (1 and 2). So 2/8 of the numbered sections are less than three.

There are three numbers from one to eight that are greater than five (6, 7, and 8). So 3/8 of the numbered sections are greater than five

Probability of getting a number less than three: 2/8

Probability of getting a number greater than five: 3/8

Probability of getting either in a single spin = 2/8 + 3/8 = 5/8

Answer:

The expression E (3B + A) is defined. The size of the resulting matrix is (1 x 1).

Step-by-step explanation:

Let's consider the following operations between matrices.

E (3B + A)

B is a matrix of (4 x 1), that is, it has 4 rows and 1 column. Let F = 3B. This is the product of a scalar by a matrix, which results in a matrix of the same size as the original. Then, F is a matrix of (4 x 1).

Now, let's consider the sum F + A, which we well call G. We can sum F and A because they are of the same size and we will get G, a matrix of the same size, (4 x 1).

Finally, we have the product E . G. We can multiply 2 matrices of sizes (m x k) and (k x n), that is, the number of columns of the first matrix must be equal to the number of rows of the second matrix, and the resulting matrix has a size (m x n). This is the case because E is (1 x 4) and G is (4 x 1), and the resulting matrix will be (1 x 1).
