b. 19.8, 4.9 d. 15.8, 3.2

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

525

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer:

Step-by-step explanation:

Quadrant 1 is at the top right, Quadrant 2 is at the top left(counter clock-wise), Quadrant 3 is at the bottom left, and Quadrant 4 is at the bottom right.

Quadrant 1 = (+x, +y)

Quadrant 2 = (-x, +y)

Quadrant 3 = (-x, -y)

Quadrant 4 = (x, -y)

So, the point C is in Quadrant IV.

To convert the fraction 2/4 to a decimal, we can perform the division 2 divided by 4 using long division or mental math.

2 ÷ 4 = 0.5

Therefore, 2/4 as a decimal is 0.5.

\( {\underline {\boxed {\Large {\bf \gray { {120}^{\circ} } }}}} \)

Given :

• In ∆ JKL , all the three interior angles have equal measures.

• Measure of \( \angle \) 1 ( Exterior angle )

Here, we can solve this question in two ways.

______________________________

Let us calculate the measure of interior angles first.

→ Let the measure of each interior angle be x.

As all the interior angles of the triangle are equal,

\( \sf { \dashrightarrow {180}^{\circ} = {x}^{\circ} +{x}^{\circ}+{x}^{\circ} } \)

[ By angle sum property of ∆ ]

\( \sf { \dashrightarrow {180}^{\circ} = {3x}^{\circ} } \)

\( \sf { \dashrightarrow \dfrac{{180}^{\circ}}{3} = {x}^{\circ} } \)

\( \sf\red { \dashrightarrow {60}^{\circ} = {x}^{\circ} } \)

Therefore, measure of each interior angle of the triangle is 60°.

As we know that,

\( \sf { \dashrightarrow \angle 1 = \angle K + \angle L} \)

\( \sf { \dashrightarrow \angle 1 = {60}^{\circ} + {60}^{\circ} } \)

\( \sf \green { \dashrightarrow \angle 1 = {120}^{\circ} } \)

⇒ Hence, measure of angle 1 is 120°.

→ \(\angle \) 1 + \(\angle \) J = 180°

→ \(\angle \) 1 + 60° = 180°

→ \(\angle \) 1 = 180° - 60°

→\(\angle \) 1 = 120°

⇒ Hence, measure of angle 1 is 120°.

because  first you need to add 2,944 +2,944=5,888 than i multiplied 46 times 128= 5888

Answer:

D

Step-by-step explanation:

A kitchen makes 23 gallons of soup a week, so double that to get 46 which would be your answer.

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer:

Place the dot in the middle of -1 and -2!

Step-by-step explanation:

You have to add 2 -2 2/6 and 5/6 that will get you -1 3/6. Then you have to find where it goes. If you would simplify the number you would get -1 1/2. This means the dot would be placed in the middle of 2 numbers. Since it is 1 and 1/2 you would need to place it between -1 and -2.

Answer:

Let the amount of gunpowder that contains 9 kg nitre be x kg. ∴ The amount of gunpowder containing 9 kg nitre is 12 kg.

So, about 200 kg gunpowder

A power is two numbers that one is the base and the other is the power.

To calculate a power fraction, both the numerator and the denominator are multiplied the same, so:

\(\boldsymbol{\sf{\left(\dfrac{5}{6}\right)^{2}=\dfrac{5\times5}{6\times6}=\dfrac{25}{36} }}\)

Since the fraction 25/36 does not have a half, that is, it is already in reduced form, so it is no longer possible to simplify it.

Answer:

Total weight = 70.5 kg

Step-by-step explanation:

Rectangular frame is made from 5 straight pieces of metal. One of them goes through the diagonal of the rectangle.

2 pieces form the length of the rectangular frame, hence, they have a length of 12 m each

2 pieces from the width of the rectangular frame, hence, they a length of 5 m each

To find the length of the diagonal, we can use Pythagoras Theorem:

Hypotenuse² = Base² + Perpendicular²

Hypotenuse² = 5² + 12²

Hypotenuse² = 169²

Hypotenuse = 13

Hence, the length of the piece of metal placed at the diagonal is 13cm

Find the sum of all lengths of the metal pieces.

Total length = 12 + 12 + 5 + 5 + 13

Total length = 47 m

Total weight = 1.5 × Total length

Total weight = 1.5 kg/m × 47m

Total weight = 70.5 kg

The total weight of the metal in the frame is 70.5 kg

If a rectangular frame is made from 5 straight pieces of metal, with a length of 5m and a width of 12m

Get the diagonal

\(d^2= 5^2 + 12^2\\d^2 = 25 + 144\\d^2 = 169\\d= 13m\)

Get the perimeter of the rectangular frame:

Perimeter of the frame = 2(5 + 12) + 13

Perimeter of the frame = 2(17) + 13

Perimeter of the frame = 34 + 13

Perimeter of the frame = 47m

If the weight of the metal is 1.5 kg per metre, the total weight will be expressed as:

Total weight = 47 * 1.5

Total weight = 70.5kg

Hence the total weight of the metal in the frame is 70.5 kg
