When a number n is decreased by 7 and then the result is multiplied by 4, the product is equal to 88. Write
an equation and solve it to find the value of n.
Answer:
n=29
Step-by-step explanation:
Not sure how to write an equation for it.
But, I did 88 divided by 4 which is 22 then plus 7 29
88/4+7=n that is the best I can think of.
If a number n is decreased by 7 and then the result is multiplied by 4, the product is equal to 88. The equation is 4(n-7)=88 and value of n is 24.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
a number n is decreased by 7 and then the result is multiplied by 4
Decreased means subtracted, the number seven is subtracted from n, which gives us n-2.
Then n-2 is multiplied by 4
4(n-2)
the product is equal to 88.
4(n-2)=88
Now we need to solve for n.
Apply distributive property on left hand side
4n-8=88
Add 8 on both sides
4n=96
Divide both sides by 4
n=24
Hence the value of number n is 24 and the Equation for sentence is 4(n-7)=88.

Which measure of central tendency most closely describes Harry's overall
performance on the math tests?
Answer:
Mode
Step-by-step explanation:
The mode is the measure of the central tendency in which the number is appeared many times

Step-by-step explanation:

The attached table
Required
Rule of the table
First, we calculate the slope(m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (3,27)[/tex]
[tex]m = \frac{27 -0}{3 - 0}[/tex]
[tex]m = \frac{27}{3}[/tex]
[tex]m = 9[/tex]
The table equation is:
[tex]y - y_1 = m(x - x_1)[/tex]
So, we have:
[tex]y - 0 = 9(x - 0)[/tex]
[tex]y - 0 = 9(x)[/tex]
[tex]y= 9x[/tex]
Hence:
[tex]f(x) = 9x[/tex]

Sean is paid biweekly. His annual salary is $42,500. What is his biweekly salary to the nearest cent?
Answer: $1,634.62
Step-by-step explanation:
There are 52 weeks in a year. However, Sean does not get paid every week, he gets paid every other week. 52/2 = 26, thus he gets paid 26 times a year.
His annual salary is 42,500. To figure out his salary in each paycheck, divide the net salary by the number of pay periods per year. In this case 42,500/26.
42500/26 = 1,634.62 (rounded to the nearest cent)

the boss gives all his employees a 6% raise, paul used to earn $11 an hour now he earns
Answer:
Now he earns $11.66 per hour.
Step-by-step explanation:
6% raise
This means that now the employees will earn 100% + 6% = 106% = 1.06 of the previous amount they earned, that is, their previous earnings will be multiplied by 1.06.
Paul used to earn $11 an hour now he earns
Multiplying by 1.06
11*1.06 = 11.66
Now he earns $11.66 per hour.

PQR. QR, QS, Q QR, QP, R QP, QS, Q QS, QR, P
Answer:
QR, QS, Q
Step-by-step explanation:
It is found that Line segment QR is part of Line QS. Point Q is the vertex of angle
What is a line segment?A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
The point of their joint is called vertex of that angle.
If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.
A line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed.
We can conclude that Line segment QR is part of Line QS. Point Q is the vertex of angle

Find the y-component of this
vector:
Answer:
The y-component of the vector is approximately -67.844 meters.
Step-by-step explanation:
A vector [tex]\vec v[/tex] in rectangular form are defined by the following form:
[tex]\vec v = (r\cdot \cos \theta, r\cdot \sin \theta)[/tex] (1)
Where:
[tex]r[/tex] - Magnitude, measured in meters.
[tex]\theta[/tex] - Direction with respect to +x semiaxis, measured in sexagesimal degrees.
Please notice that the y-component of the vector corresponds to the second component of the definition. If we know that [tex]r = 101\,m[/tex] and [tex]\theta = 222.2^{\circ}[/tex], then the y-component of the vector is:
[tex]y = r\cdot \sin \theta[/tex] (2)
[tex]y = (101\,m)\cdot \sin 222.2^{\circ}[/tex]
[tex]y \approx -67.844\,m[/tex]
The y-component of the vector is approximately -67.844 meters.

Which score has the highest relative position: a score of 38 on a test with a mean of 30 and a standard deviation of 10, a score of 4.2 on a test with a mean of and a standard deviation of or a score of 432 on a test with a mean of and a standard deviation of (Assume that the distributions being compared have approximately the same shape.)
Answer:
A score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 has the highest relative position.
Step-by-step explanation:
Which score has the highest relative position: a score of 38 on a test with a mean of 30 and a standard deviation of 10, a score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 or a score of 432 on a test with a mean of 396 and a standard deviation of 40.
In order to find the solution, we need to calculate the z score value for each test.
The z score formula: [tex]z = \dfrac{\bar{x} -\mu}{s}[/tex] where [tex]\bar{x}[/tex] is the score, μ is the mean and s is the standard deviation.
Now for test 1:
Put [tex]\bar{x}=38, \mu=30 \text{ and } s=10[/tex] in the above formula.
[tex]z = \dfrac{38 -30}{10}[/tex]
[tex]z = 0.8[/tex]
For test 2:
Put [tex]\bar{x}=4.2, \mu=2.5 \text{ and } s=1.2[/tex] in the above formula.
[tex]z = \dfrac{4.2 -2.5}{1.2}[/tex]
[tex]z \approx 1.417[/tex]
For test 3:
Put [tex]\bar{x}=432, \mu=396 \text{ and } s=40[/tex] in the above formula.
[tex]z = \dfrac{432 -396}{40}[/tex]
[tex]z =0.9[/tex]
Since the z score value of test 2 is greater so a score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 has a highest relative position.

Here is a tricky but fun problem involving large exponents or high powers.
Which of the following numbers is greater, 31¹³ or 17¹⁷?
Answer:
17 ^17
Step-by-step explanation:
Its power is bigger
You shouldn't be tricked because 31 is more than 17
Step-by-step explanation:
Notice that 31 + 1 = 32 = 2⁵ and 17 - 1 = 16 = 2⁴.
31¹³ < 32¹³
= (2⁵)¹³ = 2⁶⁵
= 2(2⁴)¹⁶ = 2 * 16¹⁶
< 16¹⁷ < 17¹⁷.
Hence 17¹⁷ is greater than 31¹³.

At a local coffee shop, the manager has determined that 56% of drink orders are for specialty espresso drinks and 44% are for plain coffee. The manager also noted that 40% of customers order food. For customers who purchase the specialty espresso drinks, 35% also purchase a food item, and for customers who purchase plain coffee, 30% also purchase a food item. What is the probability that a randomly chosen customer will purchase a specialty espresso drink and a food item?
Answer:
0.196
Step-by-step explanation:
Let :
Expresso drink = A
Plain coffee = B
Food = F
P(A) = 0.56
P(B) = 0.44
P(F) = 0.40
P(F|A) = 0.35
P(F|B) = 0.30
Probability that a customer purchases a specialty expresso coffee and a food item :
P(F|A) =. P(F n A) / P(A)
P(F n A) = P(F|A) * P(A)
P(F n A) = 0.35 * 0.56
P(F n A) = 0.196
