Answer 1

Answer:

9/70

Step-by-step explanation:

Given that:

70 students choose to attend one of three after school activities: football, tennis or running.

There are 30 boys. 13 students choose football, of which 9 are girls. 31 students choose tennis. 9 girls choose running.

A student is selected at random.

What is the probability this student chose running?

Since it asking for the probability of this student (randomly select) chose running. And we can see that there are 9 girls choose running.

Therefore, we also know 70 students is the total

Hence, the answer is 9/70

WHAT DO I DO I NEED HELP

...................

This is easy....

First, the frequency is how many times a number or certain value in a set of data appears...

So basically, its asking you for the number of times that a number in between 0 and 9 appears in the data set:

23, 15, 18, 11, 30, 32, 47, 5, 9, 10, 0, 34, 39, 49, 9

To make this easier, we can put them in numerical order.

0,5,9,9,10,11,15,18,23,30,32,34,39,47,49

Now, just single out the numbers before 10.

0,5,9,9

4 numbers, so its 4. The number of times a number between 0 and 9 appears in the data set is 4. That goes in the Frequency side...

An astronaut drops a hammer on the Moon as part of an experiment. Before the drop, he raises the hammer by a height of 1 m, which increases its gravitational potential energy by 1.2 J. The mass of the hammer is 0.75 kg. Calculate the gravitational field strength on the Moon.

Answers

Answer:

  1.6 N/kg

Step-by-step explanation:

The units of gravitational field strength are newtons per kilogram. The joule is a derived unit equivalent to a newton·meter.

Then the field strength is ...

  newtons/kg = (1.2 N·m)/((1 m)(0.75 kg)) = 1.6 N/kg

Find the formula for an inverse proportion, knowing that its graph goes through the point: A(8, 0.125) PLEASE EXPLAIN WELL! THANK YOU

Answers

The formula for the given inverse proportion is:

y = 1/x

How to get the formula of the inverse proportion?

The general formula of an inverse proportion is written as:

y = k/x

Where k is the constant of proportionality.

In this case, we know that the point (8, 0.125) belongs to the graph, then replacing these values on the general formula we get:

0.125 = k/8

Solving for k we get:

0.125*8 = k = 1

Then the inverse proportion is:

y = 1/x

Johnson cut a round pizza into 12 equal pieces. He ate 4 adjacent pieces. What is the measure of the angle of the pizza that Johnson ate?

A.
48°

B.
90°

C.
120°

D.
160°

Answers

The answer is C, because the angle is obtuse, but also not as big as 160°

Answer:

C 120 degrees

Step-by-step explanation: 3 times 4 equals 12 so if 4 peices are eaten then there is only 2/3 left so theres only 240 degrees left of the pizza so we take 360 minus 240 we get 120 so there is 120 degrees of pizza eaten by johnson.

Solving a One-Variable Linear Equation

Answers

Answer:

[tex]\Longrightarrow:\boxed{\sf{h=14}}[/tex]

Step-by-step explanation:

Isolate the term of h from one side of the equation.

Use the distributive property.

Distributive property:

→ A(B+C)=AB+AC

7h-5(3h-8)=-72

First, multiply expand.

⇒ -5(3h-8)

⇒ -5*3h=-15h

⇒ -5*8=40

Rewrite the problem.

→ -15h+40

⇒ 7h-15h+40=-72

⇒ 7h-15h=-8h

→ -8h+40=-72

Subtract by 40 from both sides.

⇒ -8h+40-40=-72-40

Solve.

⇒ -72-40=-112

⇒ -8h=-112

Then, you divide by -8 from both sides.

⇒ -8h/-8=-112/-8

Solve.

Divide the numbers from left to right.

→ -112/-8=14

[tex]\Longrightarrow: \boxed{\sf{h=14}}[/tex]

Therefore, the correct answer is h=14.

what polynomial must be added to 3xsquared + 4x+7 to obtain a sum of zero

Answers

The polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 is; -3x² -4x +7.

Let the polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 be represented by P.

In essence;

P + 3x² +4x + 7 = 0.

By subtracting 3x² +4x + 7 from both sides of the equation to obtain the value of P; we have;

P = 0 -3x² -4x +7.

Ultimately, P = -3x² -4x +7.
