Lol somebody tell me the awnser pls

Answer:

Binomial = 0.8724

Normal approximation = 0.873

Step-by-step explanation:

Given that :

Sample size (n) = 20

p = 0.6

q = 1 - p = 1 - 0.6 = 0.4

.using normal approximation :

Mean = np

Mean (m) = 20 * 0.6 = 12

Standard deviation (s) = √npq

s = √(20 * 0.6 * 0.4) = 2.1908902

Probability of 10 or more lines in use :

p(x ≥ 10)

Applying for correction:

p(x ≥ 10 - 0.5) = p(x ≥ 9.5)

Using the z formula :

Z = (x - m) / s

Z = (9.5 - 12) / 2.1908902

Z = - 1.141

p(Z > - 1.141) = 0.87307 (Z probability calculator)

p(Z > - 1.141) = 0.873

Using the binomial distribution :

P(x = x) = nCx * p^x * (1 - p)^(n-x)

p(x ≥ 10) = p(x = 10) + p(x = 11) +.... + p(x = 20)

Using calculator :

p(x ≥ 10) = 0.87247

= 0.873

Answer:

The answer is "[tex]\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] , \left[\begin{array}{c}-6&2&0&1\\\end{array}\right][/tex]"

Step-by-step explanation:

Given value:

[tex]A= \left[\begin{array}{cccc}1&3&5&0\\0&1&4&-2\\\end{array}\right][/tex]

First you find the general Ax = 0 solution for the free variables.

[tex][A \ \ \ 0]= \left[\begin{array}{cccc}1&3&5&0\\0&1&4&-2\\\end{array}\right]\\\\ R_1\to R_1-3R_2\\\\= \left[\begin{array}{ccccc}1&0&-7&6&0\\0&1&4&-2&0\\\end{array}\right][/tex]

Its general solution is:

[tex]x_1 = 7x_3-6x_4,\ \ x_2=-4x_3+2x_4 \ \ with\ \ x_3, and \ x_4\ free. \ So,[/tex]

[tex]x=\left[\begin{array}{c}x_1&x_2&x_3&x_4\\\end{array}\right] = x_3\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] + x_4\left[\begin{array}{c}-6&2&0&1\\\end{array}\right][/tex]

Null A is:  [tex]{\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] , \left[\begin{array}{c}-6&2&0&1\\\end{array}\right] }[/tex]

Answer:

[tex]\frac{2}{4}[/tex]

Step-by-step explanation:

Remember that in order to find the slope of two points you need to substitute the variables and subtract making sure you keep the 2's and the 1's together.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Plugin your numbers:

[tex]=\frac{7-5}{9-5}[/tex]

[tex]7-5=2[/tex]

[tex]9-5=4[/tex]

[tex]=\frac{2}{4}[/tex]

Answer:

The pattern would produce main effects for both A and B, and an interaction

Step-by-step explanation:

When there is a two factor experiment having two types of level of factor A and the two level of factor B also the three of the treatment that are similar and the one is totally distinct from the others

So here the treatment pattern would be the pattern in which the important and main impact would be generated for both A and B and then an interaction

hence, the last option is correct

Answer:

Step-by-step explanation:

Given the amount of detectors sold in the current year = 350

percent increment = 105%

To get the amount sold the previous year, we will use the expression;

(105% of x) + x =  350

1.05x = 350 + x

1.05x + x = 350

2.05x = 350

x = 350/2.05

x = 170.7

Hence the amount sold the previous year was 170.7 detectors

Answer:

I believe that A. pie chart, is the correct answer.

Step-by-step explanation:

This is because, a pie chart is a graph that shows the percentages of different things as they relate to a whole.

A pie chart would represent this scenario best because it would have different sections for each task, as well as the amount of employees that preform each task. Together, each task would result in the whole amount of employers.

This is why this graph would be the most appropriate.

Hope this helps! :)

Answer:

D. -4

Step-by-step explanation:

The formula for calculating the slope of his indifference curve at his current consumption is expressed as:

M = -∆y/∆x

∆y is the change in y axis

∆x is the change in x axis

Since apples are put in the horizontal axis, ∆x = 20

Since banana are on the y axis, then ∆y = 80

Substituting the given values into the formula

M = -80/20

M = -8/2

M = -4

Hence the slope of his indifference curve at his current consumption is -4.

Option D is correct.

Answer:

(0, 0)

Reasoning:

Y-intercept means set x to 0 and solve, therefore;

[tex]y=1/3(0) -1y[/tex]

[tex]y=0-1y[/tex]

[tex]2y=0[/tex]

[tex]y=0/2=0[/tex]

Thus, the y-intercept is (0,0)

I hope this helps you and good luck!

Answer:

Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.

Answer: 4.56 x 10^-3

Step-by-step explanation: To convert scientific notation to standard form, all you have to do is move the decimal to the left or the right until you get a number that is more than 1 and less than 10, then count however many spaces you had to move and add that as your exponent over 10 (if you move left, the exponent is positive, and right is negative). Basically, this just lets you know that the actual number is that many times smaller or larger than the number in your answer.

Answer:

slope: 5/7

0.714 mile per hour

Step-by-step explanation:

slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)

Mile per hour: 5/7 cross multiply with x/1, make into an equation:

7x=5 x 1

7x = 5

x = 0.714

Answer:

$15

Step-by-step explanation:

It is given that,

Last weekend, Nina mowed 4 lawns and received $60. This weekend she mowed 6 lawns and received $90.

We need to find the constant of proportionality.

First we can find the money received when she mowed 1 lawn for last weekend.

4 lawns = $60

1 lawn = $15

Then, we will find the money received when she mowed 1 lawn for this weekend.

6 lawns = $90

1 lawn = $15

Hence, the constant of proportionalityis $15.

Step-by-step explanation:

6/2=3

Answer:

0.77

Step-by-step explanation:

You solve the inner first, then move to the outer.

Plug in x = 20 for g(x) = [tex]\frac{2x+2}{x-6}[/tex]. It should give you [tex]\frac{42}{14}[/tex], which simplifies to 3.

You then need to solve f(x) with the given value from g(x), which is 3.

Plug in x = 3 for the equation [tex]\sqrt{0.4x^2-x}[/tex], and you should get [tex]\sqrt{0.6}[/tex].

The answer is roughly 0.77.

Answer:

An equation looks something like this: 4x2=8

In an equation each value on the opposite side of the equal sign is equal unless its unsolved and u need to solve it.

In an inequality, a <, >,  ≥ or ≤ separates 2 values that are unequal. < is a less than sign, > is a greater than sign and so on and so forth. An inequality gives all possible answers for an equation. For example 3x+2≤ 8 is showing us that 3x+2 is any value below or equal to 8. ≤ is a less than OR equal too sign.

in the equation 4x-5≤15 the inequality is showing us that 4x-5 is every possible value below or equal to 20. So an answer could be 19, 18, -5, 7 and basically every number below or equal to 20.

Answer/Step-by-step explanation:

Given:

m<3 = 83°

The following are the angle measures of the seven angles including the justification of each answer.

m<1 = m<3 (corresponding angles are congruent)

m<1 = 83° (substitution)

m<2 + m<3 = 180° (same side consecutive interior angles are supplementary)

m<2 = 180° - m<3 (Subtraction property of equality)

m<2 = 180 - 83

m<2 = 97°

m<4 + m<3 = 180° (linear pair)

m<4 = 180 - m<3 (Subtraction property of equality)

m<4 = 180 - 83 (substitution)

m<4 = 97°

m<5 = m<3 (vertical angles are congruent)

m<5 = 83°

m<6 = 180° - m<3 (linear pair theorem)

m<6 = 180 - 83°

m<6 = 97°

m<7 = m<3 (alternate interior angles are congruent)

m<7 = 83°

m<8 = m<6 (corresponding angles are congruent)

m<8 = 97°

Answer:

(29.14 ; 30.06)

Step-by-step explanation:

Given that'

Sample size (n) = 57

Mean (m) = 29.6

Population standard deviation (σ) = 2.7

Confidence interval = 80%

= (1 - 0.8) / 2 = 0.1

Mean ± z * σ/√n

Using the Z probability calculator : Z0. 1 = 1.28

Hence,

29.6 ± 1.28 * (2.7 / √57)

29.6 - (1.28 * 0.3576237) ; 29.6 + (1.28 * 0.3576237)

29.142241664 ; 30.057758336

(29.14 ; 30.06)
