Answer:

The probability that both of Eduardo’s partners for the group project will be girls is        

Step-by-step explanation:

Given : A hat contains slips of paper with the names of the 26 other students in Eduardo’s class on them, 10 of whom are boys. To determine his partners for the group project, Eduardo has to pull two names out of the hat without replacing them.

To find :  What is the probability that both of Eduardo’s partners for the group project will be girls?

Solution :

Total number of students = 26

Number of boys = 10

Number of girls = 26-10=16

Eduardo has to pull two names out of the hat without replacing them.

For the first hat,

Favorable outcome of getting girl = 16

Total number of outcome = 26

For the second hat, without replacement

Favorable outcome of getting another girl = 15

Total number of outcome = 25

The probability that both of Eduardo’s partners for the group project will be girls is

Hope This Helps :D

One number is larger than another by 9. If the greater number is increased by 10, and the lesser number is tripled, the sum of t
kkurt [141]

Answer:

The larger number is -6, the smaller number is -15

Step-by-step explanation:

We have two numbers, a and b.

We know that one number is larger than another by 9.

Then we can write:

a = b + 9

then a is larger than b by 9 units.

If the greater number is increased by 10 (a + 10) and the lesser number is tripled (3*b), the sum of the two would be -41:

(a + 10) + 3*b = -41

So we got two equations:

a = b + 9

(a + 10) + 3*b = -41

This is a system of equations.

One way to solve this is first isolate one variable in one of the two equations:

But we can see that the variable "a" is already isolated in the first equation, so we have:

a = b + 9

now we can replace that in the other equation:

(a + 10) + 3*b = -41

(b + 9) + 10 + 3*b = -41

now we can solve this for b.

9 + b + 10 + 3b = -41

(9 + 10) + (3b + b) = -41

19 + 4b = -41

4b = -41 -19 = -60

b = -60/4 = -15

b = -15

then:

a = b + 9

a = -15 + 9 = -6

a = -6

Osama starts with a population of 1,000 amoebas that increases 30% in size every hour for a number of hours, h. The expression 1
Blizzard [7]

Answer: The correct option is A, itis the product of the initial population and the growth factor after h hours.

Explanation:

From the given information,

Initial population = 1000

Increasing rate or growth rate = 30% every hour.

No of population increase in every hour is,

1000\times \frac{30}{100} =1000\times 0.3

Total population after h hours is,

1000(1+0.3)^h

It is in the form of,

P(t)=P_0(t)(1+r)^t

Where P_0(t) is the initial population, r is increasing rate, t is time and [tex(1+r)^t[/tex]  is the growth factor after time t.

In the above equation 1000 is the initial population and (1+0.3)^h is the growth factor after h hours. So the equation is product of of the initial population and the growth factor after h hours.

Therefore, the correct option is A, itis the product of the initial population and the growth factor after h hours.

Experiments on learning in animals sometimes measure how long it takes mice to find their way through a maze. The mean time is 1
Dahasolnce [82]

Answer:

<h3>Option c) H_a:\mu is correct</h3><h3>The alternate hypothesis for the significance test is H_a:\mu</h3>

Step-by-step explanation:

The alternate hypothesis use the sumbol for the population value

Let p be the proportion , Mean be \mu and stadard deviation be \sigma

The null hypothesis states that population value is equal to the value mentioned in the given claim.

H_0:\mu=18 (by given).

The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )

∴ H_a:\mu

The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.

<h3>∴ option c) H_a:\mu is correct.</h3>

A shop sells chocolate, vanilla and strawberry ice creams. 45% of the ice creams sold are vanilla, and 1/4 are strawberry. What
OverLord2011 [107]

Answer:

30%

Step-by-step explanation:

Well since we know that 45% is vanilla that means we have part of our answer

Also we know we sold 1/4 strawberry which in percent that would be 25%

If we add 45% with 25%  45+25=70 then since something can only be 100%

100%-70%=30%

you sold 30% chocolate
