Answer:

6

Step-by-step explanation:

20% of 10 is 2. So at the end of the first day there were 10-2=8 Crickets left. 25% of 8 is 2 so we subtract 2 from 8 to get 6, which is the answer.

Alex is writing statements to prove that the sum of the measures of interior angles of triangle PQR is equal to 180°. Line m is
Crank

Answer: The stuff in pink is the stuff I found based on the information given. The pink 40 comes from the blue 40. The reason that both of those angles are congruent is because they are alternate interior angles. This is the same reason about the angles whose measurements are 60. So the following things are true that we found that weren't already given: Angle PQR is 40 Angle PRQ is 60

I ate 8/15 of the total amount of soup, then 140 ml of it remained in the bowl. how many milliliters of soup were there in the b
charle [14.2K]
Let t=original amount of soup

8/15 of t is 140
“Of” means multiply, “is” means equal to
Therefore
8/15t=140
t=140*15/8
t=262.5

How much more would $8,000 earn in four years compounded daily at 5% than compounded annually at 5%?
QveST [7]

Answer:

Given the statement:

8,000 earn in four years compounded daily at 5%

To find the amount we use formula:

A = P(1+\frac{r}{n})^{nt}

where P is the principal , A is the amount , n is number of times compounded per year and t is the time in year.

Here, Principal(P) = $8000, r = 5% and n = 365

Substitute these given values we get;

A_1= 8000(1+\frac{5}{365})^{365 \cdot 4}

A_1= 8000 \cdot 1.000137^{1460}

A_1= 8000 \cdot 1.22141

Simplify:

A_1= \$9771.28

To find the Interest we use formula:

I_1= A_1-P

I_1= 9771.28 -8000 = \$1771.28

It is also given that:

8,000 earn in four years compounded annually at 5%.

Here, P = $8000, r = 5% , t =4 year and n = 1

Using the same formula to calculate the amount:

A_2 = 8000(1+\frac{5}{1})^{1 \cdot 4}

A_2= 8000(1.05)^4

Simplify:

A_2= \$9724.05

To find the Interest :

I_2= A_2 - P

I_2= 9724.05 - 8000= \$1724.05

Then;

I_1-I_2 = 1771.28-1724.05 = \$47.23

Therefore, $47.23 more would  $8,000 earn in four years compounded daily at 5% than compounded annually at 5%

Determine if the following probability experiment represents a binomial experiment. If​ not, explain why. If the probability exp
blondinia [14]

Answer:

C. ​No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.

Step-by-step explanation:

Given that an experimental drug is administered to 90 randomly selected​ individuals, with the number of individuals responding favorably recorded.

We find here the no of trials are 90 but we cannot say the probability is the same for all trials.

In other words, each individual may have a different probability to respond.

Since p , the success for each trial may differ for each trial binomial cannot be accepted

C. ​No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
