There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club

g100num [7]

Given:
64 total students
x = drama club students
y = yearbook club students

x = y + 10
y = 64 - x

y = 64 - x
y = 64 - (y + 10)
y = 64 - y - 10
y + y = 64 - 10
2y = 54
2y/2 = 54/2
y = 27

x = y + 10
x = 27 + 10
x = 37

To check:

x + y = 64
37 + 27 = 64
64 = 64

Rebecca moves to a large city that had two event stadiums. The larger stadium can hold 4.5 times 10^4 people, which is about 15

NNADVOKAT [17]

Answer:

3,000 people

Step-by-step explanation:

Total number of people larger stadium can hold equals 4.5 times $10^{4}$ people,

which equals 45,000 people.

Now,

it is given that larger stadium can hold 15 times more people than small stadium .

So, smaller stadium will hold 15 times less people than the larger stadium ,

Which equals , $\frac{45000}{15}$ = 3,000 people.

Thus ,

Smaller stadium can hold a total of 3,000 people.

Gabbys age is two times mikhails age.the sum of their ages is 75. What is mikhails age

Tatiana [17]

Answer:

Mikhail's age is 25 years old

Step-by-step explanation:

Let's make an equation: Say Mikhail is x, so Gabby would be 2*x=2x

If the sum of their ages equals 75, then x+2x=75, and x=2x=3x, so 3x=75.

75/3=25

Suppose that the handedness of the last fifteen U.S. presidents is as follows:40% were left-handed (L)47% were Democrats (D)If a

lesantik [10]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Probability that they were left handed P(L)= 40%

Probability that they were Democrats P(D)= 47%

So, P(L∩D) = 135 = 0.13

Now, to check whether they are independent or not.

We will find P(L) × P(D) is given by

$P(L)\times P(D)=0.47\times 0.40=0.188$

Since P(L) . P(D) ≠ P(L∩D)

So, they are not independent.

Hence, Option 'c' is correct.
