Answer:
X=-15
Step-by-step explanation:
Multiply both sides by 11
5x-2=-77
add 2 to both sides
5x=-75
Divide both sides by 5
x=-15
The value of x equal to -15 will make the given equation a true statement.
What is an equation?It is a mathematical statement that shows that two mathematical expressions are equal.
The given equation is
(5x-2) / 11 = -7
Multiply both sides by 11
i.e. 5x-2 = -77
Then add 2 to both sides
i.e. 5x = -75
Divide both sides by 5
i.e x = -15
Hence, the value of x that will make the equation 5x-2/11 = -7 a true statement is -15.

Becky just measured herself and found out she is 65 inches tall. The last time she measured, she was 52 inches tall. What percent taller is Becky now?
Answer:
25%
Step-by-step explanation:
52 - 65 = 13 in growth.
13 = 25 % of 52.
So, Becky is now 25% taller.
A price was first decreased by 12%, then it was decreased again by an additional 5%. What is the percent of the total decrease?
Answer:
The answer is 16.4%
Step-by-step explanation:
The total decrease of price percentage is 16.4% when the price was decreased by 12% .
Evaluating decrease price :
The first discount reduces the price to (100 - 12)%
= 88% which is 0.88 times the original price.
The second discount reduces the already discounted price to
(100 - 5)% =
95% of the discounted price
(0.95 times the discounted price). Get 2 discounts combined
Final Price = (0.95)(0.88) x (Original Price)
= 0.836 x (Original Price)
This is 83.6% of the original price, so the total discount rate is
(100 - 83.6)%
= 16.4%.
Stephen invests $2,000 in a savings account paying 6% annual interest. Find the balance after 5 years if the interest is compounded quarterly.
Final answer:
The balance in the savings account after 5 years, with quarterly compounded interest, will be $2,699.80.
Explanation:
To find the balance after 5 years when the interest is compounded quarterly, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(nt)[/tex]
Where:
- A is the final amount
- P is the principal amount (initial investment)
- r is the annual interest rate (in decimal form)
- n is the number of times the interest is compounded per year
- t is the number of years
Plugging in the given values:
[tex]A = $2,000(1 + 0.06/4)^(4*5)[/tex]
[tex]A = $2,000(1.015)^20[/tex]
A = $2,000 * 1.3499
A ≈ $2,699.80
After 5 years, the balance in the savings account will be approximately $2,699.80.

passes through (1, -3), slope = -1
Answer:
The needed line equation is : x + y + 2 = 0
Step-by-step explanation:
The slope m of the given line equation = -1
The points through which the line passes is (1,-3).
Now,as we know:
The POINT SLOPE form of the equation with point (x0,y0) is given as:
y - y0 = m (x-x0)
So, the equation if line q=with m = -1 and (x0,y0) = (1,-3) is given as
y - (-3) = -1( x - 1)
or, y + 3 = 1 -x
or, x + y + 2 = 0
Hence, the needed line equation is : x + y + 2 = 0

Antoine made $33,284 last year. He receives a 4.5% annual raise. What will his new salary be
Answer:
$34781.78
Step-by-step explanation:
$33,284 * 1.045 = $34781.78
The new salary will be $34781.78
Last year salary = $33284
Annual raise = 4.5%
Therefore, based on the above figures the new salary will be:
= $33284 + (4.5% × $33284)
= $33284 + (0.045 × $33284)
= $33284 + $1497.78
= $34781.78
Based on the calculation above, the new salary will be $34781.78

She buys a total of buttons.
Write a formula for in terms of and .
Answer:
Let the number of packets be x and the number of boxes be y.
Then, the formula is 6x + 15y
Step-by-step explanation:
The formula for the total number of buttons Nomusa buys, represented by t, in terms of the number of packets, p, and boxes, b, she buys is: t = 6p + 15b.
Explanation:In this mathematical context, let's suppose that Nomusa buys p packets and b boxes of buttons. The total number of buttons can be represented by the letter t. Since there are 6 buttons in a packet and 15 buttons in a box, the total number of buttons Nomusa buys will be the sum of all buttons in the packets and boxes she buys. Thus, the formula in terms of p (packets) and b (boxes) will be: t = 6p + 15b.

A newspaper conducted a statewide survey concerning the 1998 race for state senator. The newspaper took a SRS of n=1100 registered voters and found that 570 would vote for the Republican candidate. Let p represent the proportion of registered voters in the state who would vote for the Republican candidate. We test H0:p=.50 Ha:p>.50 (a) What is the z-statistic for this test? (b) What is the P-value of the test?
Part A
p = 0.5 is the hypothesized population proportion
x = 570 is the number of successes
n = 1100 is the sample size
phat = x/n = 570/1100 = 0.518182 is the approximate sample proportion
SE = standard error
SE = sqrt(p*(1-p)/n)
SE = sqrt(0.5*(1-0.5)/1100)
SE = 0.015076 which is approximate
----
We have enough to compute the z test statistic
z = (phat - p)/(SE)
z = (0.518182 - 0.5)/(0.015076)
z = 1.206023
z = 1.21
Answer: The z-statistic is approximately 1.21==============================
Part B
Compute the probability of getting a z score larger than 1.21
P(Z > 1.21) = 1 - P(Z < 1.21)
P(Z > 1.21) = 1 - 0.8869 .... see note below
P(Z > 1.21) = 0.1131
note: the value 0.8869 comes from the table that I've attached as an image below. I have marked in red the proper row and column used to look up the value. The z table is commonly found in statistics textbooks toward the back sections. There are also many free online z tables you can search out as well. I used a z table found online. Alternatively, you can use your TI83 or TI84 calculator to compute the area under the normal curve. You would use the normalCDF function.
Answer: The P-value is approximately 0.1131The z-statistic for testing whether the proportion of voters favoring the Republican candidate is greater than 0.50 is approximately 1.36. The P-value associated with this z-statistic is roughly 0.0869, indicating the probability of observing such sample results if the true proportion was indeed 0.50.
A newspaper conducted a statewide survey regarding the 1998 race for state senator, sampling n=1100 registered voters, with 570 favoring the Republican candidate. We are testing the hypotheses H₀: p = .50 against Ha: p > .50, where p represents the proportion of registered voters in the state who would vote for the Republican candidate. The steps for calculating the z-statistic and the P-value are outlined.
Calculation of the z-statistic:
To calculate the z-statistic for this test, we use the formula z = (p' - p₀) / √(p0(1 - p₀) / n), where p' = 570/1100 = 0.518 is the sample proportion, and p₀ = 0.50 is the null hypothesis proportion. Plugging in the numbers, we get:
z = (0.518 - 0.50) / √(0.50(1 - 0.50) / 1100) ≈ 1.36.
Calculation of the P-value:
The P-value is the probability that, assuming H0 is true, we would observe a sample proportion as extreme as or more extreme than the one observed. For a z-statistic of 1.36 in a right-tail test, the P-value can be found using a Z-table or software, resulting in:
P-value ≈ 0.0869.
To conclude, based on the calculated P-value, the decision on whether or not to reject the null hypothesis would depend on the level of significance (α) chosen for the test.

You and three friends spend $35 on tickets at the movies.Write and solve the equation to find the price p of one ticket.
Final answer:
The price of one movie ticket, represented as p, can be found by dividing the total cost of $35 by the number of friends, which is 4. The equation is 4p = 35, and solving for p gives $8.75 per ticket.
Explanation:
To calculate the price of one movie ticket when you and three friends spend a total of $35 on tickets, you would set up an equation where p represents the price of one ticket. The equation will be:
4p = 35
To solve for p, you would divide both sides of the equation by 4:
p = 35 / 4
p = $8.75
Therefore, the price of one movie ticket is $8.75. The calculated value of p is $8.75, indicating that each movie ticket costs $8.75. This method allows for the precise determination of individual ticket prices based on the total amount spent by the group, facilitating accurate financial planning for movie outings.
