Answer: 40% of the time the coin came up tails.
Step-by-step explanation:
The coin is tossed 20 times. Of those 20 times, it came up tails 8 times (8/20). 8/20 = 0.4 = 40%
Answer:
It’s 1/2 (the probability of getting either heads or tails) to the power of 8 (for 8 tosses).
1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2=1/128=0.00390625 =40%

3x - 2y = 1
3(5) - 2(7) = 1
15 - 14 = 1
1 = 1
2.) No
2x + 8y = 26
2(-3) + 8(-4) = 26
-6 - 32 = 26
-38 ≠ 26
Answer:
1. yes 2. no
Step-by-step explanation:
1. 3(5)-2(7)=1 √
2. 2(-3)+8(-4)=-38 not 26 ×

Answer:
We conclude that:
[tex]20\times \:3\frac{1}{5}=64[/tex]
Step-by-step explanation:
Given the expression
[tex]20\:\times 3\frac{1}{5}[/tex]
convert mixed number to improper fraction: [tex]a\frac{b}{c}=\frac{a\times c+b}{c}[/tex]
i.e. [tex]3\frac{1}{5}=\frac{3\times 5+1}{5}=\frac{16}{5}[/tex]
so the expression becomes
[tex]20\:\times 3\frac{1}{5}\:=20\times \:\frac{16}{5}[/tex]
Factor the number: 20 = 5×4
[tex]=5\times \:4\times \frac{16}{5}[/tex]
Cross-cancel common factor: 5
[tex]=4\times \:16[/tex]
Multiply the numbers: 4×16 = 64
[tex]=64[/tex]
Therefore, we conclude that:
[tex]20\times \:3\frac{1}{5}=64[/tex]
An animal reserve has 20,000 elk. The population is increasing at a rate of 8% per year. This can be modeled by the function P(t) = 20,000 (1.08)^t where t represents time in years and P(t) represents the elk population. What is the estimated population of elk in 6 years?
Answer:
The answer would be 31,737 elks.
Step-by-step explanation:
You would solve this by multiplying 1.08 by the power of 6 which equals 1.586874322944. You would then multiply this number by 20,000 which equals 31,737.4865 but since you can’t have .4865 of an elk the answer is just 31,737.

1760 upper primary pupils took part in a sports meet in 2014. This was decreased of 20% when compared to 2015. The number of the upper primary pupils who took part in 2016 increased by 5% when compared to 2015. How many upper primary pupils took part in the sports meet in 2016?
Answer:
Number of upper primary pupils who took part in the sports meet in 2016 is 1478.
Step-by-step explanation:
Total number of upper primary pupils who took part in the sports meet in 2014 is 1760. It was decreased of 20% compared to 2015.
So that,
20% of 1760 = [tex]\frac{20}{100}[/tex] x 1760
= 0.2 x 1760
= 352
Number of upper primary pupils who took part in the sports meet in 2015 = 1760 - 352
= 1408
Also,
5% of 1408 = [tex]\frac{5}{100}[/tex] x 1408
= 0.05 x 1408
= 70.4
Number of upper primary pupils who took part in the sports meet in 2016 = 1408 + 70.4
= 1478.4
With an increase of 5% compared to 2015, the number of upper primary pupils who took part in the sports meet in 2016 is 1478.

2) Dylan walked 1/3 miles in 20 minutes How far will he goes in miles distance in 120 minutes?
Answer:
Question 1 : If you mean how many miles will he run in 1 hour then it is 1 Mile | Question 2 : 2 Miles
Step-by-step explanation:
Question 1 :
1/4 x 4 (because of the hour being split into fourths) = 1 Mile
Question 2 :
120 / 20 = 6, 6 x 1/3 = 6/3, simplified = 2

Colin was helping his uncle clean up a construction site. Colin's job was to make a neat stack of scrap wood. Each piece of wood was 1 3/8 inches thick. At the end if the day, Colin's stack was 57 3/4 inches tall. How many pieces of wood were in Colin's stack?
Answer:
a) 1/2 of an energy bar
b) 42 pieces
Step-by-step explanation:
a) Here, Franklin are 3/4 of an energy bar while Trey are 2/3 of what Franklin ate
The fraction are by Trey is 2/3 * 3/4 = 6/12 = 1/2
b) To find the number of pieces of wood present, we will need to divide the height of Colin’s stack by the thickness of each piece of wood
Mathematically, that will be;
57 3/4 divided by 1 3/8
= 231/4 * 8/11 = 42 pieces

For the second question, 4 busses and 3 cars.
Step-by-step explanation:
It's really simple actually, but sorry I can't come up with an equation. You can just add or multiply students per bus and students per car until you get to 195. Each bus can hold 45 students, so 45 x 4 = 180. Each car can hold 5 students, so 5 x 3 = 15. In total, 15 + 180 = 195 students.

Stacy's Weekly salary is $1516.52 what is her annual salary?
Answer:
Does she get paid once every week?
Step-by-step explanation:
On Saturdays, Eve earns $14 per hour for yard work and an extra amount for dog walking. Look at the table. Choose the linear function f Eve can use to determine her pay.
Hours 1 2 3 4 5
Pay 26 40 54 68 82
A. f(x) = x + 14
B. f(x) = 12x + 16
C. f(x) = 12x + 14
D. f(x) = 14x + 12
The linear function f Eve can use to determine her pay would be; D. f(x) = 14x + 12
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is the form Ax + B = 0.
Given that Eve earns $14 per hour for yard work and an extra amount for dog walking on Saturdays.
The table shows the data;
Hours 1 2 3 4 5
Pay 26 40 54 68 82
Thus, the linear function f Eve can use to determine her pay is;
f(x) = 14x + 12
To check;
f(x) = 14x + 12
f(x) = 14(1) + 12
f(x) = 14 + 12 = 26
Hence, The linear function f Eve can use to determine her pay would be; D. f(x) = 14x + 12
