Can somebody Help me pls !

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.

Answer:

The student should have divided the discounted amount by the percent. The percent should have been written as a decimal.

Answer:

2 over 1

Step-by-step explanation:

step 1

multiply the denominator by the whole number

5×1=5

step 2

add the answer from step 1 to the numerator

5+5=10

step 3

write answer from step 2 over the denominator

10/5

10÷5=2 so,the answer is 2 over 1

5÷5=1

The answer is 2000kg

Step-by-step explanation:

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.

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]

In this problem:

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.

Kosi traced a rectangle on a coordinate grid. The rectangle had the following vertices: (−6, 5), (2, 5), (2, –1), and (–6, –1). Which of the following numbers are dimensions of the rectangle? Select each correct answer. A. 4 units B. 5 units C. 6 units D. 7 units E. 8 units F. 9 units. help, please!.

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

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

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.

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

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

Where:

Given the following data:

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.

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.

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!

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

  4(3x - g) + 4x

= 4×3x - 4×g + 4x

= 12x - 4g + 4x

= 16x - 4g

  9(4g + 1) - 5g

= 9×4g + 9×1 - 5g

= 36g + 9 - 5g

= 31g + 9

Look up to their vertexes

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).

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.

Answer:

Yes

Step-by-step explanation:

A for loop basically relies on repeating the same code for a pre-set number of times. During which you can make any code repeat inside of it, including indexing through a type of list. Many times a for-loop will use the indexes in a list to calculate the number of times that the loop has to repeat. This is usually done in order to search or apply changes in an array of other types of data structures that have countless values stored in it.
