To find the percent, you have to divide 24/6
24/6 = 0.25
Now you convert 0.25 to a percent.
So move the decimal point 2 places to the right.
= 25 %

Clara bought 24 donuts for the office. If 6 of the donuts were chocolate, what percent of the donuts were chocolate.

The fraction $\frac{6}{24}$ represents the donuts that are chocolate out of all the donuts.

To find what percent of donuts are chocolate, we can turn the fraction $\frac{6}{24}$ into a percent.

We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 6 and 24 using 6.

6 ÷ 6 = 1

24 ÷ 6 = 4

Our reduced fraction is $\frac{1}{4}$ .

1 ÷ 4 = 0.25

0.25 × 100 = 25%

Therefore, 25% of the donuts that Clara bought were Chocolate.

Lunch break: In a recent survey of 655 working Americans ages 25-34, the average weekly amount spent on lunch was $43.5

Inga [223]

Using the Empirical Rule, it is found that:

a) Approximately 99.7% of the amounts are between $35.26 and $51.88.
b) Approximately 95% of the amounts are between $38.03 and $49.11.
c) Approximately 68% of the amounts fall between $40.73 and $46.27.

------------

The Empirical Rule states that, in a bell-shaped distribution:

Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.

-----------

Item a:

$43.5 - 3(2.77) = 35.26$

$43.5 + 3(2.77) = 51.88$

Within 3 standard deviations of the mean, thus, approximately 99.7%.

-----------

Item b:

$43.5 - 2(2.77) = 38.03$

$43.5 + 2(2.77) = 49.11$

Within 2 standard deviations of the mean, thus, approximately 95%.

-----------

Item c:

68% is within 1 standard deviation of the mean, so:

$43.5 - 2.77 = 40.73$

$43.5 + 2.77 = 46.27$

Approximately 68% of the amounts fall between $40.73 and $46.27.

The function, y(r)=2.76r , is used to convert Russian rubles in Japanese yen, and the function, P(y)=0.16y , is used to convert

timurjin [86]

They probably want 880 pesos, since they asked you do intermediate rounding

but a more accurate answer would be
883.20 pesos

To combine the functions, you'd substitute in 2.76r for y in 0.16y. This would give you 0.16(2.76r), which simplifies to 0.4416r, but they want you round this to the nearest hundredth, so its really 0.44r. Substitute in the 2000 for r and you get 0.44 * 2000 which is 880 pesos

AD= DC= Angle a= Angle b= Angle c=

Nadya [2.5K]

9514 1404 393

Answer:

AD= 8

DC= 15

Angle a= 112°

Angle b= 68°

Angle c= 112°

Step-by-step explanation:

We have to assume the figure is a parallelogram.

Opposite sides of a parallelogram are congruent, so ...

BC = AD = 8

AB = DC = 15

Opposite angles are congruent, and adjacent angles are supplementary.

180° - ∠D = Angle a = Angle c = 112°

∠D = Angle b = 68°

In a survey, a group of students were asked to name their favorite day of the week. There were 8 students who chose “other”.

lara [203]

5 % of the students choose other. 95% choose either Saturday or Sunday.
Let x be the number of students who participated.

(5/100) * x = 8 Multiply both sides by 100
5 * x = 8*100
5*x = 800 Divide by 5
x = 800/5
x = 160 students participated in the survey <<<<< Answer
