someone help please!!

Answer:

See explanation.

Step-by-step explanation:

Aim of experiment:

To discover the amount of time (average amount of time) that 7th grade students spend on homework each week.

Name of researcher:

Mary.

Requirements for the experiment:

- knowledge of the number of hours that some or all of the students spend on homework each week

- knowledge of the total number of 7th grade students (population statistics)

The issue or problem with this question is that it doesn't say what Mary found out after her research. There are no result statistics from the experiment! Mary surveyed 20 students out of the 164. Her findings will/can be used to infer about the population. Those findings are absent here, hence the question can't be solved.

Answer:

C

Step-by-step explanation:

A vertical stretch is accomplished by multiplying the parent by the stretch factor (given as 4 in this problem).  At that point, the function is

h(x) = 4x

To flip over the x-axis, change the sign of the function's rule.

g(x) = -4x

In the attached image, f(x) = x is purple, h(x) = 4x is black, g(x) = -4x is red.

It has 0 lines of symmetry because we cannot reflect any portion of itself over the line to land on another portion. For example, we cannot draw a vertical line through the center and reflect the right half over to the left side. The arrow doesn't match or line up properly.

It does however have rotational symmetry. The angle of rotation is 360/3 = 120 degrees. We can rotate the figure 120 degrees, either clockwise or counterclockwise, and the resulting figure will be 100% identical to the original figure. In short: after the rotation, no change has been made. This is because the arrows are effectively going in a circle. Applying a rotation to a circle does not change the circle overall.

Answer:

For the company to break even, the number of units sold is 500 units

Step-by-step explanation:

To get this number of units, we simply substitute the value of 0 for p

we have this as;

0 =x^2 -2500

x^2 = 2500

x = √2500

x = 500 (we do not consider the other root of x = -500 since the number of quantities cannot be negative)

Answer:

2.95 cans of soup

Step-by-step explanation:

A large can of soup contains 19 fl oz A serving is about eight Oz How many Canz should you buy if you want to serve How many Cans should you buy if you want to serve 7 people

Step 1

From the above question:

1 serving = 1 Person

1 person = 8oz

7 persons = x

Cross Multiply

x = 7 × 8oz

x = 56 oz

Step 2

56 oz will serve 7 people

M

From the question also, we are told that:

19 oz = 1 can of soup

56 oz = x

Cross Multiply

19x = 56 × 1

x = 56 /19

x =2.9473684211 cans of soup

Approximately

2.95 cans of soup will serve 7 peop

Answer:

x = 13

Step-by-step explanation:

Solving for X:

46 = 4x-6

46 + 6 = 4x

52 = 4x

Step-by-step explanation:

Answer:

b = 6.7 cm

Step-by-step explanation:

Here, we want to find the value of b

to do this, we are going to use the law of sines

And this law is that the ratio of the measure of a side and the sine of the angle facing the side is constant for all the sides of a triangle

Thus, we have it that;

a/sin A = b/sin B = c/sin C

Before we proceed, we need the measure of the last angle

That would be 189 minus the sum of the two given angles

we have this as;

180 - (82 + 55) = 43

Thus;

b/sin 43 = 8/sin 55

b = 8 sin 43/sin 55

b = 6.7 cm

Answer:

Without going to tables:

Suppose 1$ originally deposited

After 18 years using A (1 + i)^18 = 1.04^18 = 2.0258 $

Interest earned on the 1$ was 1.0258

How many $ deposited to earn $72

72 / 1.0258 = 70.18

So the original deposit was 70.188

Check:

70.188 * (1.04)^18 = 142.19 Collected at 18

If 70.18 was initially deposited then

142.19 - 70.18 = 72  is the interest earned

Answer:

$0.98 each bottle

Step-by-step explanation:

We know:

cost of popcorn= $1.84

number of bottles= 8

total cost= $9.68

cost of all bottles=

total cost−cost of popcorn

=

9.68−1.84

=

7.84

cost per bottle=

number of bottles/cost of all bottles

=

8
=

7.84/8
=

0.98
