There are 12 boys and 14 girls in mr.gupta's math class. find a number of ways mr gupta can select a team of 3 students from the class to work on a group project . the team consists of 1 girl and 2 boys?
a.924
b.80
c.4368
d.20

Answers

Answer 1

The answer is (a) 924.

To form a team of 3 students with 1 girl and 2 boys, we need to select 1 girl from the 14 girls and 2 boys from the 12 boys.

The number of ways to select 1 girl from 14 is C(14,1) = 14, and the number of ways to select 2 boys from 12 is C(12,2) = 66.

By the multiplication principle, the total number of ways to form the team is the product of these two numbers:

14 * 66 = 924

Therefore, the answer is (a) 924.

suppose you plunk $5000 into a one-year certificate of deposit (CD) that pays simple interest at 3% per annum. The interest you earn after one year would be $150:​

Answers

Simple Interest
Simple interest is calculated using the following formula:

Simple Interest
=
P
×
r
×
n
where:
P
=
Principal amount
r
=
Annual interest rate
n
=
Term of loan, in years


Simple Interest=P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years

The simple interest for a deposit of $ 5,000 at 3 % rate of interest for 1 year would be $ 150

What is Simple Interest?

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the simple interest be represented as S

Now , the value of S is

The principal amount = $ 5,000

The rate of interest R = 3 %

The time period T = 1 year

So , the Simple Interest is given by the equation

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

Simple Interest S = ( 5000 x 3 x 1 ) / 100

On simplifying the equation , we get

Simple Interest S = 150000 / 100

Simple Interest S = $ 150

Therefore , the value of S is $ 150

Hence , the simple interest for the deposit is $ 150

Answer:

C

Step-by-step explanation:

Because the circle is not shaded in, it doesn't count the number it's on:

So it would be a < or >.

Because this is on a number line and the shaded part goes to the left, it will be < because it points to the left.

The non-shaded circle is on 4, so your answer, x, will be:

x < 4

But the answer choices don't have this, meaning you have to simplify all of them.

The first one is:

x + 9 < 5

x < -4

x - 5 < 9

x < 14

x + 5 < 9

x < 4

x - 9 < 5

x < 14

So it would be C.

Television is measured by the diagonal. A 55-inch tv has an actual diagonal length of 54.8 inches. Its height is 27 inch Mr.Schlagers entertainment center is 49 inches wide will the tv fit the entertainment center?

Answers

Answer:

47.68 inches

Step-by-step explanation:

As seen in the diagram attached below we can see that the tv is a rectangle. We are given the diagonal and the height which means we have to find the length. Since the tv diagonal forms a right triangle we can use the Pythagorean theorem to solve for the length. This theorem would be the following.

[tex]a^{2} + b^{2} = c^{2}[/tex]

where a and b are the sides of the triangle and c is the diagonal.

[tex]27^{2} + b^{2} = 54.8^{2}[/tex]

[tex]729 + b^{2} = 3,003.04[/tex]

[tex]b^{2} = 2,274.04[/tex]

[tex]b = 47.68[/tex]

Finally, we can see that the length of the TV is 47.68 inches

Asystem of equations has 1 solution. If 4x - y = 5 is one of the equations, which could be the - y = 4x + 5 y = 4x - 5 2y = 8x - 10 - 2y = 8 - 10​

Answers

Step-by-step explanation:

step 1. The first equation 4x - y = 5 has a slope of 4. The 2nd equation simply cannot have the same slope for there to be 1 solution.

step 2. -y = 4x + 5. This has a slope of -4 so "yes" it could work.

step 3. y = 4x - 5. "no".

step 4. 2y = 8x - 10. The slope is 8/2 = 4. "no".

step 5. -2y = 8x - 10. The slope is 8/-2 = -4. "yes".

I think before we get to this answer we need to understand how roots of a quadratic equation works.

When a quadratic equation have 2 real roots such as a/b and c/d we can write the quadratic equation in factored form like this y or 0=(bx-a)(dx-c)

In this case we know the 2 roots are 5 and 2/3 and one of the factors is already x-5. so the other one according to the equation above that I wrote have to be 3x-2 and therefore the 3rd choice is correct.

Algebra 1 Please help! thank u sm

Answers

Answer:

1. Slyvia is wrong. You treat the numbers normally when dividing the left side, so 3.61/4.1 = .88. When dividing the exponents, you subtract the numerator from the denominator, so -11-7 = -18. So, you do have .88 * 10^-18, at first, but when you are working in scientific notation you want the decimal to be greater than so, which requires us to add an additional -1, to make it 8.8 instead of 0.88. This is because we want to move the decimal place left one more time. This results in our final answer being 8.8 * 10^-19, which is not Slyvia's answer.

2. Dylan's answer is correct. He subtracted the exponents correctly, then moved the decimal place over one place towards the left.

3. Ethan is wrong. He added the exponents, instead of subtracting. However, you cannot do this, because when you are dividing exponents, you must subtract.

Step-by-step explanation:

I have this acronym I learned called MADSPM, which has helped me a lot. I never learned it in Algebra, but I wish that they had taught it. Each letter corresponds with an exponent rule. If this makes sense, here is what it stands for:

When you multiply, you add.

When you divide, you subtract.

When there are parentheses, you multiply.

In this case, it was solely division. So, you just need to remember division = subtraction, when it comes to exponents.

Hopefully this helped. If you need me to explain it better, please let me know, and I will try. Thanks much & have a wonderful day!

Find the exact value of sin space 2 theta when tan theta equals negative 12 over 5 where fraction numerator 3 pi over denominator 2 end fraction less or equal than theta less or equal than 2 straight pi.

Answers

Answer:

-120/169

Step-by-step explanation:

Sin2theta = 2sintheta costheta

Given that tan theta = -12/5

Opposite = -12

Adjacent = 5

Using Pythagoras theorem

Hyp = √(-12)²+5²

Hyp = √144+25

Hyp = √169

Hyp = 13

Cos theta = adj/hyp

Cos theta = 5/13

Sin theta = opp/hyp

Sin theta = -12/13

Substitute

Sin2theta = 2(-12/13)(5/13)

Sin2theta = -120/169

Hence sin 2theta = -120/169
