Answer:

  3(5h - 2g)

= 3×5h - 3×2g  

= 15h - 6g

  5(12g - 4f)

= 5×12g - 5×4f

= 60g - 20f

  2(h - 3g)

= 2×h - 2×3g

= 2h - 6g

When given vertices for a geometric shapes we find the lengths of the side by using the formula:

When(x1, y1) and (x2, y2)

= √(x2 - x1)² + (y2 - y1)²

A= (−6, 5),B = (2, 5), C = (2, –1), and D = (–6, –1).

For AB

A= (−6, 5),B = (2, 5),

= √(2 -(-6)² + (5 - 5)²

= √8² + 0

= √64

= 8 units

For BC

B = (2, 5), C = (2, –1),.

√(2 - 2)² +(-1 - 5)²

= √0 + -6²

= √36

= 6 units

For CD

C = (2, –1), and D = (–6, –1).

= √(-6 -2)² + (-1 -(-1))²

= √-8² + 0²

= √64

= 8 units

For AD

A= (−6, 5), D = (–6, –1).

= √(-6 -(-6))² + (-1 - 5)²

= √0² + -6²

= √36

= 6 units

Therefore, the following numbers that are dimensions of the rectangle is

C) 6 units

E) 8 units

[tex]x=15[/tex]

Answer:

Okay so yes the answer is 15

Step-by-step explanation:

It begins with 4X11 which is 44

So the equation becomes 44-x+4=33

Then I add 44 plus 4 which is me adding all the available terms which is 48

Then I subtracted 33 from 48 to find the value of x

And 48-33=15

So there you pretty much have it.

To be sure you can plug the answer in.

4x11=44

44-(x) which is 15 so 44-15=29

29+4=33

There ya have it!

A different camera is selling for $7.50 off the regular price. It was marked down 15%. A student used the equation:

and found the regular price of the camera to be $112.50.

Explain the error(s) in the student’s work.

Answers

Answer:

The original price is $50. The student's mistake in the equation is that he should have done 7.5/0.15

The student should not have multiplied, instead divided. He also didn't put 15 in a decimal form, which would have messed the whole equation up.

A cylidrical container of height 28cm and diameter of 18cm is with water. The water is then poured into another container with a rectangular base of length 27cm and width 11cm . Calculate the depth of the in the container.

Answers

Answer:

23.9894949495cm is the depth of the container.

Step-by-step explanation:

Cylindrical container:

height: 28

radius: 9 (or 18/2)

pi * 9² = 254.4690049408

254.4690049408 * 28 = 7,125.1321383424 cm²

cylidrical container area: 7,125.1321383424cm²

Container:

length: 27cm

width: 11cm

27 * 11 = 297

7,125.1321383424 / 297 = 23.9894949495cm

I assume that the container with rectangular base is precisely full when tou pour the water into it.

And that your question was how deep the container was.

Answers

Using the normal distribution and the central limit theorem, it is found that:

a) The mean is of 0.15.

b) The standard deviation is of 0.0326.

c) There is a 0.063 = 6.3% probability that less than 10% of the incoming kindergarteners are nearsighted.

d) 0.1774 of incoming kindergarteners are nearsighted.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

In this problem:

It is generally believed that nearsightedness affects about 15% of all children, hence p = 0.15.A local elementary school registered 120 incoming kindergarteners, hence n = 120.

Item a:

[tex]\mu = p = 0.15[/tex]

The mean is of 0.15.

Item b:

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.15(0.85)}{120}} = 0.0326[/tex]

The standard deviation is of 0.0326.

Item c:

The probability is the p-value of Z when X = 0.1, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.1 - 0.15}{0.0326}[/tex]

[tex]Z = -1.53[/tex]

[tex]Z = -1.53[/tex] has a p-value of 0.063.

There is a 0.063 = 6.3% probability that less than 10% of the incoming kindergarteners are nearsighted.

Item d:

The proportion is X when Z has a p-value of 0.8, so X when Z = 0.84.

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]0.84 = \frac{X - 0.15}{0.0326}[/tex]

[tex]X - 0.15 = 0.84(0.0326)[/tex]

[tex]X = 0.1774[/tex]

0.1774 of incoming kindergarteners are nearsighted.

Given a graph for the transformation of f(x) in the format g(x) = f(x) + k, determine the k value.
two parabolas open up with f of x passing through negative 3 comma negative 3 and g of x passing through negative 3 comma 1

A. k = −3
B. k = 1
C. k = 4
D. k = 5

Answers

Look up to their vertexes

f(x) has vertex at (-3,-3)g(x) has vertex at (-3,1)

So

[tex]\\ \rm\rightarrowtail g(x)=f(x)+k[/tex]

[tex]\\ \rm\rightarrowtail g(-3)=f(-3)+k[/tex]

[tex]\\ \rm\rightarrowtail 1=-3+k[/tex]

[tex]\\ \rm\rightarrowtail k=1+3[/tex]

[tex]\\ \rm\rightarrowtail k=4[/tex]

The required value of K for the transformation of f(x) is 4. Option C is correct.

Given that,
Graph for the transformation of f(x) in the format g(x) = f(x) + k,
To determine the k value.
Two parabolas open up with f(x) passing through (- 3, - 3)and g(x) passing through  (-3, 1).

What is a parabola?

A parabola is a cross section cut out of the cone and represented by an equation

Here,
Since equation of transformation is g(x) = f(x) + k
Now put the values of the vertex in the transformation equation,
f(x) passing through (- 3, - 3)and g(x) passing through  (-3, 1).

f(-3) = -3
g(-3) = 1
g(-3) = f(-3) + k
1 = -3 + k
k = 1 + 3

k = 4

Thus, the required value of K for the transformation of f(x) is 4. Option C is correct.

The side length of an equilateral triangle is 5 centimeters. Find the length of an altitude. Round your answer to the nearest tenth.

The length of the altitude is about
centimeters.

Answers

If the side length of an equilateral triangle is 5 centimeters, the length of altitude is about 4.33 centimeters.

What is an equilateral triangle?

An equilateral triangle can be defined as a type of triangle or regular polygon that has equal side lengths and all of its interior angles are equal.

How to calculate the length of altitude.

Mathematically, the length of altitude of an equilateral triangle is calculated by using this formula:

[tex]L=\frac{\sqrt{3} }{2} a[/tex]

Where:

a is the side lengths.L is the length of altitude.

Given the following data:

Side length = 5 centimeters.

Substituting the given parameters into the formula, we have;

[tex]L=\frac{\sqrt{3} }{2} \times 5\\\\L=\frac{5\sqrt{3} }{2}[/tex]

Length = 4.33 centimeters.

The probability of an event describes the likelihood an event will occur. The likelihood of an event ranges from impossible to certain, but more common descriptions are likely to unlikely. An event is a single outcome or a group of outcomes. An outcome is a possible result of an action. Probability can be represented as a fraction, as a decimal, or as a percent. Something is fair if there is an equal chance for each outcome to occur.
