Answer:
in 11 years
Step-by-step explanation: half of 30 is 15 and 11 + 4 is 15.
Step-by-step explanation:
Ok, if the mother is 30, then half her age would be 15. Now, if the daughter is 4, you would subtract 15-4, which equals 11.
So the answer is eleven years.
Hope this helped!
Which ratio is equivalent to

$45
?
A. 4h : $36
O
B. 54lbs : 6 OZ
o
4h
$50
D.
$63
9h
Answer:
A.) 4h : $36
Step-by-step explanation:
Why it's right: they equal the same thing
5/45 = 1/9
4/36 = 1/9
Why it's wrong: similar, but backwards
54/6 = 9
Just plain wrong:
4/50 = 2/25
63/9 = 7
Victoria ran 3/4 mile on Tuesday. She ran 2.2 times further on Saturday. How many miles did she run on Saturday

If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimeters?
Complete Question
Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 143 millimetres, and a standard deviation of 5. If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimetres? Round your answer to four decimal places.
Answer:
The probability is [tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 47
The mean diameter is [tex]\mu = 143[/tex]
The standard deviation is [tex]\sigma = 5[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{5 }{\sqrt{47} }[/tex]
=> [tex]\sigma_{x} = 0.7293[/tex]
Generally the probability that the sample mean will differ from the population mean by more than 0.2 milli meters is mathematically represented as
[tex]P(|\= x - \mu | \ge 0.2 ) = P(\frac{|\= x - \mu|}{\sigma_{x}} \ge \frac{0.2}{0.7293} )[/tex]
[tex]\frac{|\= x - \mu | -\mu}{\sigma } = |Z| (The \ standardized \ value\ of \ {|\= x - \mu | )[/tex]
=> [tex]P(|\= x - \mu | \ge 0.2 ) = P(|Z| \ge 0.2742 )[/tex]
=> [tex]P(|\= x - \mu | \ge 0.2 ) = P(Z < - 2742) + P(Z > 0.2742)[/tex]
From the z table the area under the normal curve to the left corresponding to -2.742 is
[tex]P(Z < -0.2742) =0.39197[/tex]
From the z table the area under the normal curve to the right corresponding to 2.742 is
P(Z > 0.2742) = 0.39197
So
[tex]P(|\= x - \mu | \ge 0.2 ) = 0.39197 + 0.39197[/tex]
[tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]

Step-by-step explanation:
The table shows your scores in a skateboarding competition. The leader has 311.62 points. Select the equation that you can use to find how many points p you need in the fourth round to tie the leader. Then solve the equation to determine how many points you need in the fourth round to take the lead in the competition.
Find the second part please.
Answer:
✅[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
✅To take the lead, your score in the fourth round must be greater than 79.08.
Step-by-step explanation:
If you score, 63.43, 87.15, 81.96 in the first, second and third round respectively, if the current leader has a total score of 311.62 points, the point p that you need to score to equal 311.62 points, can be found using the following equation:
[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
Solve for the value of p
[tex] p + 232.54 = 311.62 [/tex]
Subtract 232.54 from each side
[tex] p = 311.62 - 232.54 [/tex]
[tex] p = 79.08 [/tex]

Step-by-step explanation:
Mathematicians seek and use patterns[8][9] to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof. When mathematical structures are good models of real phenomena, mathematical reasoning can be used to provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.
Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements.[10] Since the pioneering work of Giuseppe Peano (1858–1932), David Hilbert (1862–1943), and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. Mathematics developed at a relatively slow pace until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that has continued to the present day.[11]
Mathematics is essential in many fields, including natural science, engineering, medicine, finance, and the social sciences.

4x - 3y = -13 is (2, 7)
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is the system of equations as -
y = 3x + 1
AND
4x - 3y = -13
Plot the graph of both of these equations. The point of intersection, would be the solution of this system of equations. Refer to the graph attached. These lines intersect at (2, 7)
Therefore, the solution for the system of equations → y = 3x + 1 and
4x - 3y = -13 is (2, 7)

Your answer should be a polynomial in standard form.
(3c + 2)(c^2-6c-4)
Answer:
After expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get [tex]3c^3-16c^2-24c-8[/tex]
Step-by-step explanation:
We need to expand the polynomial [tex](3c + 2)(c^2-6c-4)[/tex]
Multiply the terms:
[tex](3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8[/tex]
So, after expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get [tex]3c^3-16c^2-24c-8[/tex]

which two ratios form a proportion
A 1:2 and 4:2
b 1:2 6:3
c2:1 2:4
d 2:1 and 6 :3
Answer:c
Step-by-step explanation:
Did the test
Answer:
D. 2:1 & 6:3
Step-by-step explanation:
Proportion means equal so we need to see which ratios are equal.
To do that we need to make one fo the numbers in the ratio equal the corresponding number in the other ratio, then see if the other matches.
A:
1:2 & 4:2
The second number is already the same but the first isn't, therefore it is not proportional.
B:
1:2 & 6:3
To get 1 to equal 6 we must multiply it by 6, and what you do to one side you must do to the other so we have to multiply 2 by 6 as well
6:12 & 6:3
The first numbers are the same but the second isn't, therefore it is not proportional.
C:
2:1 & 2:4
The first numbers are the same but the second isn't, therefore it is not proportional
D:
2:1 & 6:3
to get 2 to equal 6 we need to multiply it by 3, which means we have to multiu 1 by 3 too
6:3 & 6:3
These are equal so this is proportional.
frank is going to plant b vegetable seeds in one garden and 4b + 2 vegetable seeds in another. How many seeds is frank going to plant?
Answer:
5b + 2
Step-by-step explanation:
Frank is going to plant b vegetable seeds in one garden and 4b + 2 vegetable seeds in another.
We need to find how many seeds is frank going to plant.
It is equal to the sum of vegetable seeds in one garden and the vegetable seeds in another.
Sum = b + 4b + 2
Sum = 5b + 2
So, there are "5b + 2" seeds frank going to plant.

In order to lure new customers to a credit card, a bank is offering an initial cash back award, plus cash back amounting to a percentage of the value of all purchases made with the card the value of all purchases made with the card and the amount of cash back which of these equations does the graph represent ?
Answer:
A. [tex] c = 0.03p + 150 [/tex].
Step-by-step explanation:
The equation can be written in slope-intercept form as [tex] c = mp + b [/tex], where:
c = cash back (dollars)
p = value of purchases (dollars)
m = slope of the graph
b = y-intercept, which is the initial cash back award.
All we need to generate an equation that represents the graph, we need to find out the value of m and b.
b = until cash back award = 150
The slope, m, can be calculated using two points in the line, (1000, 180) and (2000, 210):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{210 - 180}{2000 - 1000} = \frac{30}{1000} = 0.03 [/tex]
Substitute m = 0.03, and b = 150, in [tex] c = mp + b [/tex].
The equation would be:
✅ [tex] c = 0.03p + 150 [/tex].
