Since there are no green counters, the probability of selecting a green counter is always 0 in this context.
Given that the jar contains 8 red counters and 21 blue counters, we can determine the probabilities of selecting each color.
Total number of counters in the jar = 8 (red) + 21 (blue) = 29
(a) The probability of selecting a red counter:
Number of red counters / Total number of counters = 8 / 29
(b) The probability of selecting a blue counter:
Number of blue counters / Total number of counters = 21 / 29
(c) The probability of selecting a green counter:
There are no green counters in the jar, so the probability of selecting a green counter is 0.
Therefore, the probabilities are as follows:
A. The probability of selecting a red counter is 8/29.
B. The probability of selecting a blue counter is 21/29.
C. The probability of selecting a green counter is 0.
Please note that since there are no green counters, the probability of selecting a green counter is always 0 in this context.

A shirt is on sale for 30% off. The expression p - 0.30p, where p is the original cost of the shirt, can be used to find the sale price. Which expression means the same as decreased by 30%?
Answer: 0.70
Step-by-step explanation the same as decreased by 30%" would be (1.00 - 0.30)(original cost), or 0.70(original cost)
Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds. By what percentage did Mr. Pope decrease he weight?
a. (4%)
b. (7%)
c.(10)
d.(15%)
Mr. Pope decreased his weight by 4 percent.
What is percentage?A percentage is a portion of a whole thing written as a number between 0 and 100 instead of fraction.
Given that, Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds.
we need to find the percentage of decrease of his weight,
So, basically we will use here the concept of percentage change,
Formula = final amount - initial amount / initial amount x 100
Since, he lost 10 pounds and has 240 pounds so, initially he weighted = 240 + 10 = 250 pounds
So, percentage decreased = -10 / 250 x 100 = -4% [minus is the sign for decrease]
Hence, Mr. Pope decreased his weight by 4 percent.

Em um jogo de futebol, atletas masculinos percorrem em média 11Km, sendo que a distância percorrida ao longo do primeiro tempo é superior em 5% com relação ao segundo tempo (EKBLOM, 1986; RIENZI et al., 2000). Levando em consideração que um time de futebol tem 10 jogadores de linha e todos eles percorrem a mesma distância e não são substituídos, qual a distância média total que um time pode percorrer em uma partida? *
Answer:225.5 km
Step-by-step explanation:
Alek and Ann start walking around a track at the same time and at the same place. It takes Ann 6 minutes to walk around the track, and it takes Alek 8 minutes. After how many minutes will they reach the starting point at the same time
Answer:
3 3/7 minutes
Step-by-step explanation:
This calculated using the formula:
1/x + 1/y = 1/n
Where
x = Number of minutes it took Ann to walk = 6 minutes
y = Number of minutes it took Alek to walk = 8 minutes
n = Number of minutes it would take An and Alek to reach the starting point at the same time
1/6 + 1/8 = 1/n
Lowest Common Denominator = 24
4 + 3/24 = 1/n
7/24 = 1/n
Cross Multiply
7n = 24
n = 24/7
n = 3 3/7 minutes
It would take them 3 3/7 minutes to reach the starting point at the same time.

Answer:
about 63.59 ft squared
Step-by-step explanation:
9/2 = 4.5--> Radius
Now we use the Area formula: piR^2 (Pi x radius squared)
4.5^2 = 20.25
20.25 x 3.14 = 63.59 -(rounded answer)
What is the measure of ∠A, the exterior angle of the triangle shown below?
F. m∠A = 92°, because 180 – (50 + 38) = 92.
G. m∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.m∠A=78°,because 50–38=12and90–12=78.
J. m∠A = 88°, because 50 + 38 = 88.
Answer: A is 88
Step-by-step explanation: Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88

If a_n is a sequence that includes the terms:
250, ___, 10
What missing number(s) would the missing term be if:
a) a_n is arithmetic
b) a_n is geometric
9514 1404 393
Answer:
arithmetic: 130geometric: ±50Step-by-step explanation:
Arithmetic sequence
The terms of an arithmetic sequence have common difference. If the missing term is x, then the difference between terms is the same:
x -250 = 10 -x
2x = 260 . . . . . . add 250+x to both sides
x = 130 . . . . . . . . divide by 2
The missing term of an arithmetic sequence is 130.
(the common difference is -120)
__
Geometric sequence
The terms of a geometric sequence have a common ratio. If the missing term is x, then the ratios between terms are the same:
x/250 = 10/x
x^2 = 2500 . . . . . . . multiply both sides by 250x
x = ±√2500 = ±50 . . . take the square root
The missing term of a geometric sequence is +50 or -50.
(the common ratio is ±1/5)
which of the expressions have a value of 2?
Answer:
The answers are B and E
Step-by-step explanation:
The square root of 4 is 2.
The cube root of 8 is 2.
A is wrong because its value is 4.
C is wrong because its value is 4.
D is wrong because the square root of 8 isn't whole.
Answer:
E. √4
B. ³√8
Step-by-step explanation:
You can find this simply by putting it into a calculator if you have access to one. Just type √ and 4. If you don't have a calculator, you can just use the knowledge that 2 × 2 = 4, hence why it's the square root of 4 :)
You can also determine that B is correct by doing 2 to the power of 3.
2³ = 8, so you know that B is correct too.
