Answer:

Mean = 27

Step-by-step explanation:

Given mean = 25

No of observations (N) = 8

We know,

Mean = Sum / N

25 = Sum / 8

Sum = 25 x 8

Sum = 200

Since an observation 11 is removed,

New sum = 200 - 11 = 189

New no. of observation (N) = 8 - 1 = 7

Now,

Mean of remaining observations = New Sum / New N

= 189/7

= 27

Answer:

mean=25

n=8

sum of observation=?

we have

mean=sum/n

sum=25×8=200

if one observation is excluded

sum will be =200-11=189

[n]no of observation = 8-1=7

new mean =new sum/new n=189/7=27

the mean of the remaining is 27

the perimeter is 28 feet long. you would add 7 four times because all sides on the square are equal

Answer:

Kite x=1, y=7

Step-by-step explanation:

It is a kite.

The two lines on the bottom corners of the kite mean they have the same value.

X=1 so 3x+4

3 *1 +4=7

And: x+6

1+6=7.

X+4=1+4=5.

Y=7 so y-2

7-2=5.

Answer:

m<1 = 97°

Step-by-step explanation:

<1 and 83° are same-side interior angles. Same-side interior angles are supplementary. This implies that:

m<1 + 83° = 180°

Therefore:

m<1 + 83° - 83° = 180° - 83° (subtraction property of equality)

m<1 = 97°

Answer:

<1=97°

steps:

<1+83=180 co interior angle

<1=180-83=97°

Answer:

 6%

Step-by-step explanation:

Given data

Principal= $1585

Time = 5 years

Interest =  $475.50

Rate =???

The expression for the interest is given as

SI=PRT/100

substitute

475.50=1585*R*5/100

Cross multiply

475.50*100= 7925R

47550=7925R

R= 47550/7925

R= 6%

Hence the rate is  6%

Answer:

240

Step-by-step explanation:

Hello There!

Note: the little arrows indicate that the line can be extended and it's opposite side will never touch indicating that it's a parallelogram

The formula for area of a parallelogram is

[tex]A=bh[/tex]

where b = base and h = height

the given dimension are

height = 15

base = 16

so all we have to do is plug in the values into the formula

[tex]A=(15)16\\15*16=240\\A=240[/tex]

so we can conclude that the area of the polygon is

240 square units

Answer:

p = $200

Step-by-step explanation:

90/p = 45/100

45p = 9000

p = 9000/45 = $200

Answer: 2/12

3/18

4/24

Step-by-step explanation:

Answer:

360

Step-by-step explanation:

To solve to volume you need to times the width, length, height. so 3 times 6 is 18 and 18 times 20 is 360.

Answer:

B, D, F

Step-by-step explanation:

B, D, F

A solution is any value of a variable that makes the specified equation true. A solution set is the set of all variables that makes the equation true. ... If the two sides are equal, the equation is true and thus the value is a solution.

Answer:

[tex]Amount = -\$1461.9[/tex]

Step-by-step explanation:

We have the following:

[tex]Total = 52[/tex] --- cards in a standard deck

Represent cards with a value of 5 or less with x

So:  [tex]x = \{2, 3, 4, 5\}[/tex] i.e 4 cards

However, each of these has a frequency of 4.

So: [tex]n(x) = 4\ cards* 4[/tex]

[tex]n(x) = 16[/tex]

The probability is:

[tex]p(x) = \frac{16}{52}[/tex]

The cost of this is:

[tex]C(x) = +\$7[/tex]

Represent cards with a value of above 5 with y

[tex]n(y) = 52 - 16[/tex]

[tex]n(y) = 36[/tex]

The probability is:

[tex]p(y) = \frac{36}{52}[/tex]

The cost of this is:

[tex]C(y) = -\$7[/tex] --- It is negative because you lost

In a game, your expected amount is:

[tex]E = n(x) * C(x) + n(y) * C(y)[/tex]

[tex]E = \frac{16}{52} * (+\$7) + \frac{36}{52} * (-\$7)[/tex]

[tex]E = \frac{16* \$7}{52} - \frac{36* \$7}{52}[/tex]

[tex]E = \frac{\$112}{52} - \frac{\$252}{52}[/tex]

[tex]E = \frac{\$112 - \$252}{52}[/tex]

[tex]E = -\frac{\$140}{52}[/tex]

When you play 543 times, the expected amount is:

[tex]Amount = E * 543[/tex]

[tex]Amount = -\frac{\$140}{52} *543[/tex]

[tex]Amount = -\frac{\$140 *543}{52}[/tex]

[tex]Amount = -\frac{\$76020}{52}[/tex]

[tex]Amount = -\$1461.9[/tex]

-1/4 or -1/4x

Answer:

the the figure shown x=7

Answer:

7°

Step-by-step explanation:

7x + 5 °+ 36° + 90 °= 180° ( being sum of angles of triangle )

7x + 131° = 180°

7x = 180 °- 131 °

7x = 49°

x = 49° / 7

x = 7°

Answer:

It's a, 2^x + 3

Step-by-step explanation:

If you look at the y-intercept, you can see that there was a vertical shift upwards by 3 (y intercept moved from y = 1 to y = 4).

If you're studying for the SAT, it'll be good to study the transformation rules, including horizontal stretches/shifts. They always seem to throw one or two questions about those on there.

Step-by-step explanation:

I Finish Work in 2 hrs

Work done in 1 Hr = 1/2

Brother Finish work in 3 Hrs Work done in 1 hr = 1/3

Let Say both Complete Work in T hrs as it has to be painted on both sides

Then T (1/2+1/3) = 2

=> T × 5/6 = 2

=> T = 2 Hr 24 Mins

=> T = 12/5 I will Take 2 Hrs to finish my work & 24 Mins to finish after start Helping
