9 ÷ 1/5 = ? tell me in comments please i need this answer

Answer:

Since the calculated z =-3.5357 falls in the critical region z ≥ 1.645 we reject H0 and conclude that the sample provides sufficient evidence to indicate that the true percentage of all firms that announced one or more acquisitions during the year 2000 is ≥ 30%

Step-by-step explanation:

Testing  hypothesis about a population proportion when sample size is large.

If the sample size is large then the variable

z= p^-p / sqrt [pq/n]

is approximately standard normal.

Formulate the hypotheses as

H0 : p < 30%   against the claim Ha: p ≥ 30%

Choose the significance level ∝= 0.05

the critical region is z ≥ 1.645 because the alternative hypothesis is stated on a greater  than or equal to basis.

Computing

Z= 748-(2778*0.3)/ √2778*30/100*70/100

z= 748-833.4/√583.38

z= -85.4/24.153

z=-3.5357

Since the calculated z =-3.5357 falls in the critical region z ≥ 1.645 we reject H0 and conclude that the sample provides sufficient evidence to indicate that the true percentage of all firms that announced one or more acquisitions during the year 2000 is ≥ 30%

The p- value is 0.0002

Answer:

[tex]k = 31[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4x^2 - 2x^2 + kx + 5[/tex]

[tex]r = -10[/tex] --- remainder

[tex]d = 2x + 1[/tex] --- divisor

Required

Find k

We have:

[tex]d = 2x + 1[/tex] --- divisor

Equate to 0

[tex]2x + 1 = 0[/tex]

Solve for x

[tex]2x = -1[/tex]

[tex]x =-0.5[/tex]

This means that:

[tex]f(-0.5)=-10[/tex]

So, we have:

[tex]4*(-0.5)^2 - 2*(-0.5)^2 + k*-0.5 + 5 =-10[/tex]

[tex]0.5 -0.5k + 5 =-10[/tex]

Collect like terms

[tex]-0.5k=-10-5-0.5[/tex]

[tex]-0.5k=-15.5[/tex]

Solve for k

[tex]k = -15.5/-0.5[/tex]

[tex]k = 31[/tex]

I'm going to separate it into parts

(y - 3)(y - 2)

y^2 - 5y + 6

(y - 4)(y^2 - 5y + 6)

y^3 - 5y^2 + 6y - 4y^2 + 20y - 24

y^3 - 9y^2 + 26y - 24

y^3 - 9y^2 + 26y - 24 - 5

Answer - 40

----------

100 - 4

96 - 8

88 - 16

72 - 32

Answer:

a. 880

Step-by-step explanation:

Options are "a. 880 b. 90 c. 790 d. None of these choices"

Interval estimate of between 790 and 970 books checked out per day.

Lower limit is 790, Upper limit is 970

Point estimate of μ(x) = [Upper limit + Lower limit} / 2

Point estimate of μ(x) = [970 + 790] / 2

Point estimate of μ(x) = 1760/2

Point estimate of μ(x) = 880

So, the efficient, unbiased point estimate of the number of books checked out each day at the New York City Public Library is 880.

Answer:

Perimeter = 22 feet

Step-by-step explanation:

Perimeter is the outside measurement of the shape, and the sides are 4 and 7.

What you can do is add them together and multiply by 2, so

4+7 = 11

11*2 = 22

You can also just add all sides together

4 + 7 + 4 + 7 = 22

Answer:

Given :

To Find :

Using Formula :

[tex]{ \star{\small{\underline{\boxed{\sf{\red{P = 2(l + b)}}}}}}}[/tex]

Solution :

Here the given polygon is rectangle. So, finding the perimeter of rectangle :

[tex] \begin{gathered} \qquad{\dashrightarrow{\small{\sf{P_{(Rec)} = 2(l + b)}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_{(Rec)} = 2(7 + 4)}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_{(Rec)} = 2(11)}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_{(Rec)} = 2 \times 11}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_{(Rec)} = 22 \: ft}}}} \\ \\ \qquad{\star{\small{\underline{\boxed{\sf{ \purple{P_{(Rec)} = 22 \: ft}}}}}}}\end{gathered}[/tex]

Hence, the perimeter of the polygon is 22 ft.

Answer: 1/8 of her garden

1/8 of her garden is dedicated to each type of flower.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

Given

part of stella's garden has flowers = 3/4

types of flowers = 6

fraction of her garden is dedicated to each type of flower = 3/4 / 6 = 3/4 *1/6 = 3/24 = 1/8.

Answer:

0.0097 = 0.97% probability that it is defective

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Product is shipped.

Event B: It is defective.

Probability of the product being shipped:

100 - 10 = 90% of 85%(not defective).

5% of 100 - 85 = 15%(defective). So

[tex]P(A) = 0.9*0.85 + 0.05*0.15 = 0.7725[/tex]

Probability of being shipped and being defective:

5% of 15%. So

[tex]P(A \cap B) = 0.05*0.15 = 0.0075[/tex]

What is the probability that it is defective?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0075}{0.7725} = 0.0097[/tex]

0.0097 = 0.97% probability that it is defective

Answer:

Step-by-step explanation:

Data could exists in several different forms which often dictates if the data can be used directly in its raw format or if it requires conversion to another format. The nature of data is often very robust. Some data may occur as numeric and have meaning in terms of addition and other statistical properties; however some are only dummy and are restricted to (0's and 1's). Similarly, some may be used to show rank or depth and as such have no meaning while trying to perform Mathematical calculation. Therefore, choosing statistical summaries for the data sivj as the. Mean, median and mode will depend on the input, binary data cannot be summarized using the median or mean except the use of a modal score. While the presentation of the data using graphs also rewired that the nature of the data be considered before selecting a suitable chart (linen, bar, dot, pie and so on).
