Eva is 5 years younger than 3 times Bill's age. If Eva is 2 years old, how old is Bill?
Answer:
17 years old.
Step-by-step explanation:
5 years than 3 times can be represented as 5*3.
5*3=15.
If Eva is 2, and Bill is 15 years older, 2+15=17.
Therefore, Bill is 17 years of age.

2 - 72 = - 70
It is generally believed that nearsightedness affects about 15% of all children. A local elementary school registered 120 incoming kindergarteners.
Note that this scenario is talking about a sampling distribution since this school is a sample of size 120. Therefore, you will need to calculate the standard deviation using a formula before using the normalcdf and invNorm commands.
a) What is the mean of the sampling distribution of all samples like this:
b) What is the standard deviation of the sampling distribution of all samples like this:
Give the formula with values that you entered in your calculator as a way of showing your work:
Give your final answer rounded to 4 decimal places:
c) What is the probability that less than 10% of the incoming kindergarteners are nearsighted?
Give the command and values you used as a way of showing your work:
Give your final answer rounded to 4 decimal places:
d) If this school measures at the 80th percentile for all incoming kindergarten classes of size 120, what proportion of incoming kindergarteners are nearsighted?
Give the command and values you used as a way of showing your work:
Give your final answer rounded to 2 decimal places:
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 DistributionIn 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.

3x + y = 16
X + y = 8
What are x and y
Find x-intercept
The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y1=0 and then solve for x.
3x + y = 16
3x + 1(0) = 16
x1 = 5.333 y1 = 0
Find y-intercept
The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.
3x + y = 16
3(0) + y = 16
y2 = 16 x2 = 0
A different camera is selling for $7.50 off the regular price. It was marked down 15%. A student used the equation:
15(7.5) = Original price
and found the regular price of the camera to be $112.50.
Explain the error(s) in the student’s work.
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:
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

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

Answer: 10 rows of 10
Step-by-step explanation:
What's the solution to 2x – 2 > 2x + 4?
Consider the inequality first ;
[tex]{:\implies \quad \sf 2x-2\> 2x+4}[/tex]
Subtracting 2x from both sides ;

But , as the given situation isn't possible in mathematics , so the inequality have no solutions . Or [tex]{\bf{x\in \phi}}[/tex] , where [tex]\bf \phi[/tex] is the empty set.
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.
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.

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
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).
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.

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
