At a high school the student government is made up of 5 seniors, 4 juniors, 3 sophomores and 2 freshmen. If there are 8 seniors, 9 juniors, 12 sophomores and 7 freshmen running, in how many ways can the student government be selected?

Answer:

0.40

Step-by-step explanation:

Change the divisor 1.8 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

7.2 ÷ 18 = 0.40

and therefore:

0.72 ÷ 1.8 = 0.40

Both calculated to 2 decimal places.

Answer:

Step-by-step explanation:

because a constant term is a number with out a variable

Answer:

Multiply both sides by -2 and reverse the inequality symbol

Step-by-step explanation:

since it is division you want to make it multiplication so that you can get the answer easier

-1/2w<12

it cancels out the -1/2 than just multiply 12 and -2 you get -24

w > -24

Given:

Line segment labelled y is the midsegment of the triangle.

To find:

The measures of x, y and z.

Solution:

Since line segment labelled y is the midsegment of the triangle. So, it divides the included sides in two equal parts.

Line segment labelled y is bisector of both included sides.

[tex]x=21[/tex] units

[tex]z=2\times 16[/tex]

[tex]z=32[/tex] units

According to the midsegments theorem, the length of the midsegment is half of third side or non included side of the triangle.

[tex]y=\dfrac{14}{2}[/tex]

[tex]y=7[/tex] units

Therefore, [tex]x=21\text{ units},y=7\text{ units},z=32\text{ units}[/tex].

Answer:

Step-by-step explanation:

The equation of the circumference of a circle is 2(pi)r

This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)

so a simple formula is:

arc length in radians X radius

radius = 4 cm

the area that the question wants is the oposite

of the 142 degree section so 360 - 142 = 218

218 degrees *  (pi/180) = 3.80482 rad

3.80482 * 4 = 15.21928 cm

i think it the third one but i don't know i'm not in collage math class so...

Step-by-step explanation:

Answer:

c? sorry if it's wrong...

The correct statement is,

⇒ The finding is significant at both α = 0.05 and α = 0.01.

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

For a hypothesis test of H₀, p = 0.35 against the alternative,

And, Hₐ: p > 0.35, the z test statistic is found to be 2.45.

Now, We get;

P(z < 2.45) = 0.9929

Hence, Significant is,

⇒ 1 - 0.9929 = 0.0071

Thus, Significant at both 0.05 and 0.01 because both are greater than 0.0071.

So, The correct statement is,

⇒ The finding is significant at both α = 0.05 and α = 0.01.

Answer:

the third one to the left

Step-by-step explanation:

Step-by-step explanation:

Step 1

For Ritu,

Principal(P) = Rs 100

Time(T) = 5 year

Rate(R) =8%pa

Intrest (I) = ???

We know,

I = P*T*R /100

= 100*8*5/100

=Rs40

now

For Jitu,

Principal(P) =Rs 100

Rate(R)=9%pa

Time (T) = 4 year

Intrest(I) =?

We have

I = P*T*R/100

=100*4*9/100

=Rs36

Step 2

We have

Intrest of Ritu have more then that of Jitu so she makes more profit

now Profit diffrence =Rs40-Rs36

=Rs4

Therefore Ritu gets 4 more profit then Jitu

Answer:

D: 6x - 27

Step-by-step explanation:

1. Distribute

2. Combine like terms

3. You will get your final answer

-9(x + 3) = -9x - 27

-9(x) = -9x

-9(3) = -27

-9x - 27 + 15x

-9x and 15x are like terms. So add them

-9x + 15x = 6x

So your final answer is 6x - 27.
