a coin is tossed 200 times, if the probability of getting a head is 5/8, how many times tail is obtained in all in tossing the coin?
Answer:
You would get tails 75 times, or 75:200
Step-by-step explanation:
5:8 = x:200
multiply 8 by 25 to get 200
multiply 5 by 25 to get x (125)
Probability to get heads is 125 so subtract 200 by 125
200 - 125 = 75

You recycled a total of 30 cans and bottles and made $1.80. For cans you get $0.05 and for bottles
you get $0.15. How many cans did you recycle?
Answer:
27
Step-by-step explanation:
x + y = 30
0.05x + 0.15y = 1.80
x = 30 - y
1.5 - 0.05y + 0.15y = 1.80
0.10y = 0.30
y = 3 (bottles)
x = 27 (cans)

3 to the power of negative 4 answer in fraction
Answer:
Step-by-step explanation:
[tex]3^{(-4)}=\frac{1}{3^4}=\frac{1}{81}[/tex]
3 to the power of-4 is equal to the bit 1/81.
To calculate 3 raised to the power of-4 and express the answer as a bit, we can use the fact that a negative exponent indicates the complementary of the base raised to the positive exponent.
In this case
3⁻⁴= 1/3⁴
Now, let's calculate 34 first
3⁴ = 3 x 3 x 3 x 3 = 81
Now, substitute this value back into the complementary expression
1/ 3⁴= 1/ 81
Thus, 3 to the power of-4 is equal to the bit 1/81.

The Vincent family played a game of basketball. For each game, Ben kept a record of the number of 2-point baskets he attempted, and the number of 3-point baskets he attempted. After the family played several games, he made a scatter plot of the data using the 2-point shots as the x-variable and the 3-point shots as the y-variable. The scatter plot has a line of best fit with the equation y=1.2x+3.1
Answer:
your answer is The y-intercept represents how many 3-point shots Ben will try to make if he attempts 0 2-point shots.

Two hamsters work together and move a pile of sunflower seeds in 7 1 2 minutes. How long would it take each hamster to move the same pile alone if one of the hamsters needs 8 more minutes to do the job than the other?
Answer:
Hamster 1: 12 minutes. hamster 2: 20 minutes
Step-by-step explanation:
The first hamster took 8 minutes while the second hamster tool 20 minutes.
Equation
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the time required for the first hamster and y the time for the second hamster.
x = y + 8 (1)
(1/x + 1/y)7.5 = 1
[1/(y + 8) + 1/y ]7.5 = 1
y = 12 minutes
x = 12 + 8 = 20 minutes
The first hamster took 8 minutes while the second hamster tool 20 minutes.

Brenda completes her sixth hiking trail in a state park. A park ranger tells her that she has hiked 25% of the trails. How many trails are there to hike in the state park?
Answer:
Total number of hikes in the state park = 24
Step-by-step explanation:
Let the number of trails available in the state park = t
Since, Brenda has completed 25% of the total trails, number of trails completed by her = 25% of t
= [tex]\frac{25}{100}\times t[/tex]
= 0.25t
As per ranger she has completed 6th hiking trail,
6 = 0.25t
t = [tex]\frac{6}{0.25}[/tex]
t = 24
Therefore, total number trails to hike in the state park = 24.
Answer:
24?
Step-by-step explanation:
6 is 25 so mulitplie 6x4 there 24

What does the IQR (Interquartile Range tell you)?
a. The probability of the box and whisker plot.
b. The percentage of numbers.
c. The variability for 50% of the data.
d. The average for the data.
Answer:
"interquartile range", abbreviated "IQR", is just the width of the box in the box-and-whisker plot. ... The IQR tells how spread out the "middle" values are; it can also be used to tell when some of the other values are "too far" from the central value.
