Answer:
A. 64%, B. 62%
Step-by-step explanation:
Find how many people do not have an email account.
168 + 24 = 192 Find the percentage.
192/300 = 0.64 Hence, 64% of shoppers don't have an email.
Do the same for B.
168 + 18 = 186
186/300 = 0.62
62% of shoppers don't have access to a computer.
The percentage of shopkeepers that don't have access to e-mail account are 64% and percentage of shop keepers with no computer access is 62%
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: percentage of the shoppers who don't have an e-mail account is 192 and percentage of the shoppers that don't have computer access are 186
Now total number of shopkeepers surveyed is 300
and thus percentage of shoppers do not have an e-mail account is
= 192/300 ×100
=64%
Again the total number of shopkeepers who do not have access of computer is = 186/300 × 100
=62%
Hence, The percentage of shopkeepers that don't have access to e-mail account are 64% and percentage of shop keepers with no computer access is 62%

1.69 = 106.76 - 106.4 * cosQ
Subtract 106.76 from both sides
-105.07 = -106.4 * cosQ
Divide both sides by -106.4

According to the output, the fertilizer level had a significant effect on the pH of soil samples. True False
Answers
Answer:
False
Step-by-step explanation:
In the question, it is given a output of a single factor ANOVA analysis. It provided the measure of the effect of the amount of fertilizer on the pH of the soil samples.
pH may be defined as the content of alkalinity or acidity of a solution or the sample on a logarithmic scale. The pH value of 7 is considered to be neutral.
From the data sheet in the context, the p value of the ANOVA analysis is 0.8324. This value is very large value. So the results are not very statistically significant. As the p value is large, therefore, the answer is false.

In TRIANGLE ABC, what is the value of x?
Answers
Answer:[tex]70^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle BAC=112^{\circ}\\\angle BCM=(2x+12)^{\circ}\\\angle ABL=2x^{\circ}[/tex]
[tex]\angle ACB[/tex] is given by [tex]180^{\circ}-\angle BCM[/tex] as the angle around a straight line is [tex]180^{\circ}[/tex]
[tex]\therefore \angle BCA=180^{\circ}-2x^{\circ}-12^{\circ}\\\angle BCA=(168-2x)^{\circ}[/tex]
Also, using exterior angle property. We can write
[tex]\angle BCA+\angle BAC=\angle ABL[/tex]
Insert the values
[tex]\Rightarrow 168^{\circ}-2x^{\circ}+112^{\circ}=2x^{\circ}\\\Rightarrow 280=4x^{\circ}\\\Rightarrow x=70^{\circ}[/tex]
The population of a town is increasing at a rate of 6.2% per year. The city council believes they will have to add another elementary school when the population reaches 100,000. If there are currently 76,000 people living in the town, how long do they have before the new school will be needed?
Answers
Answer:
The correct solution is "4.6".
Step-by-step explanation:
Given:
Interest rate,
r = 6.2%
or,
= 0.062
Amount,
A = 100000
Principle,
P = 76000
As we know,
⇒ [tex]A=P(1+\frac{r}{100} )^n[/tex]
On substituting the values, we get
⇒ [tex]100000=76000(1+\frac{6.2}{100} )^n[/tex]
⇒ [tex](1+0.062)^n=\frac{100}{76}[/tex]
On taking log both sides, we get
⇒ [tex]n \ log_e(1.062)=log_e(\frac{100}{76} )[/tex]
⇒ [tex]n=\frac{ln(\frac{100}{76} )}{ln(1.062)}[/tex]
By putting the values of log, we get
⇒ [tex]=4.5622[/tex]
or,
⇒ [tex]=4.6[/tex]

O B. $994.60
O c. $912.86
O D. $972.84
Answers
$972.84 is invested in total after 1 year.
Correct option is (D)
What is compound interest?Compound interest is generally understood to be interest that is earned on both the original investment and any subsequent interest. Compound interest is, thus, the interest earned on both the initial principal and the interest that has already been accrued on this principal.
As per the given data:
Compounding frequency (n) = 12
Final value (FV) = $1000
Time period (t) = 12 months = 1 year
[tex]FV = P(1+\frac{r}{n})^{nt}[/tex]
FV – Future worth of the investment is the final balance in our calculation.
P – Initial balance (the value of the investment);
r – Annual interest rate (in decimal);
n – Number of times the interest is compounded per year (compounding frequency); and
t – Numbers of years the money is invested for.
Substituting the given values
[tex]1000 = P(1+\frac{0.06}{12})^{12 \times 1}[/tex]
[tex]P = \$ 972.84[/tex]
Hence, $972.84 is invested in total after 1 year.

Sofia has 25 coins in nickels and dimes in her pocket for a total of $1.65. How many of each type of coin does she have? First complete the equations below, where N stands for nickels and D stands for dimes. [?]N + [ ]D = 1.65; N + D
Answers
Answer:
Step-by-step explanation:
Let n represent nickels & d dimes
given: n + d = 25 #1 (number of coins)
given: .05n + .10d = 1.65 #2 (amount in dollars)
n = 25 - d #3 (rewrite of #1)
.05(25 -d) + .10d = 1.65 (substitute #3 in #2)
1.25 - .05d + .10d = 1.65 (multiply out the left side)
.05d = .40 (collection of like terms)
d = 8 (divided both sides by.05)
n + 8 = 25 (substitute answer for d in #1)
n = 17 (subtract both sides by 8)
There are 8 dimes and 17 nickels.
Check:
17(.05) + 8(.10) = 1.65 (answers in #2)
.85 + .80 = 1.65 (multiply out the left side)

A football coach expects 453 people to come to the next game. A set of bleachers holds 56 fans. If each set of bleachers costs $99, will the coach need to spend more than $1,000 for the bleachers? How can you decide without using division? and links are included to but if it is to cheat i am reporting them
Answers
Answer:
No need to spend more than $ 1,000
Step-by-step explanation:
assume the coach needs 10 set
10 set will cover 10×56 = 560 people that more than 453.
so,
the cost is only 10× $99 = $ 990
that less than $ 1,000
Answer:
Fewer than 10 sets of bleachers are needed. This is because 5610 560, which is greater than 453. The cost of 10 sets of bleachers would be $9910 $ 990, which is less than $1,000. The coach will not need to spend more than $1,000 for the bleachers.

Answers
Answer:
1520/4=380 per month
Step-by-step explanation:
The monthly payments for Anita and Casey are 230 and 150.
What is equation?"An equation is a formula that expresses the equality of two expressions consisting of variables and/or numbers, by connecting them with the equals sign =."
Assume
Monthly payments for Anita = x
Monthly payments for Casey = y
We have
Anita pays 80 more than Casey does each month.
We can write the equation
x = y + 80
x - y = 80 ...........................(1)
Over the course of 4 months, their combined bill is 1,520.
We can write the equation
4x + 4y = 1520...................(2)
Solving equations (1) and (2) by substituting equation x = y + 80 in equation (2)
⇒4x + 4y = 1520
⇒4(y + 80) + 4y = 1520
⇒4y + 320 + 4y = 1520
⇒8y = 1520-320
⇒8y = 1200
⇒y = [tex]\frac{1200}{8}[/tex]
⇒y = 150
Substitute y = 150 in equation (1)
⇒x - y = 80
⇒x - 150 = 80
⇒x = 80+150
⇒x = 230
Hence, the monthly payments for Anita and Casey are 230 and 150.
