Answer:

x = 16.5

Step-by-step explanation:

The best way to solve this is to use cross multiplication.

[tex]\frac{3}{x} = \frac{4}{22}[/tex]

4 * x = 4x

22 * 3 = 66

Your equation is 66 = 4x.

Divide both sides by 4.

66/4 = 16.5

4x/4 = x.

16.5 = x.

Therefore, your answer is 16.5.

Answer:

$25

Step-by-step explanation:

First, you would do 80 x $0.25 = $20.  (Meaning 80 math problems he answered correctly times the $0.25 he got for each one correct.)

Next, you do $45 - $20 which equals $25.

In conclusion, he gets $25 from his uncle.

Answer:

Lemmy ; 2 7/8 miles

Step-by-step explanation:

Given that :

Distance walked by Lemmy:

Saturday = 3 1/2 miles

Sunday = 4 3/4 miles

Total distance walked by Lemmy:

3 1/2 + 4 3/4

7/2 + 19/4

(14 + 19) / 4

33 / 4

= 8 1/4

Miles walked by Ronnie : 5 3/8

Lemmy walked farther because : 8 1/4 > 5 3/8

Number of distance walked farther than Ronnie :

8 1/4 - 5 3/8

33/4 - 43/8

(66 - 43) / 8

= 23/ 8

= 2 7/8 miles

Answer:

Buying 3 cans individually.

Step-by-step explanation:

If you bought 3 cans for 1.50 it would be 4.50.

If you bought a triple pack it would be 5 dollars.

So 4.50 is less than 5 dollars.

Hope this helps!

Answer:

The 3 cans of beans at 1.50 each would be cheaper than the triple pack for $5.

Step-by-step explanation:

1.50 x 3 = 4.50, which is less than (<) 5.

Question:

Find the mean and compare it with the median. Find the standard deviation and compare it with the interquartile range. Calculate s for the data 4, 1, 3, 10, 2.

Answer:

(a)

[tex]Mean = 4[/tex]

[tex]Median=3[/tex]

[tex]Mean > Median[/tex]

(b)

[tex]IQR = 2[/tex]

[tex]SD = 3.2[/tex]

[tex]SD> IQR[/tex]

Step-by-step explanation:

Given:

Data: 4, 1, 3, 10, 2.

Solving (a): The mean and the Median

The mean is calculated as follows:

[tex]Mean = \frac{1}{n} \sum x[/tex]

Where

[tex]n = 5[/tex] i.e 5 data

So, the expression becomes:

[tex]Mean = \frac{1}{5}(4 + 1+3+10+2)[/tex]

[tex]Mean = \frac{1}{5}(20)[/tex]

[tex]Mean = 4[/tex]

Calculating the Median:

First, arrange the order (ascending order):

[tex]Data: 1, 2,3,4,10[/tex]

Because n is odd

The median is represented as:

[tex]Median = (\frac{n+1}{2})th\ item[/tex]

[tex]Median = (\frac{5+1}{2})th\ item\\[/tex]

[tex]Median = (\frac{6}{2})th\ item[/tex]

[tex]Median = 3rd\ item[/tex]

From the arranged data, the 3rd item is 3.

Hence:

[tex]Median=3[/tex]

By comparison, the mean is greater than the median because [tex]4 > 3[/tex]

Solving (b): Standard Deviation and IQR

The standard deviation is calculated as follows:

[tex]SD= \sqrt{\frac{\sum (x_i - Mean)^2}{n}[/tex]

So, we have:

[tex]SD= \sqrt{\frac{(4 - 4)^2+(1 - 4)^2+(3 - 4)^2+(10 - 4)^2+(2 - 4)^2}{5}[/tex]

[tex]SD= \sqrt{\frac{(0)^2+(- 3)^2+(- 1)^2+(6)^2+(-2)^2}{5}[/tex]

[tex]SD= \sqrt{\frac{0+9+1+36+4}{5}[/tex]

[tex]SD= \sqrt{\frac{50}{5}[/tex]

[tex]SD= \sqrt{10}[/tex]

[tex]SD = 3.2[/tex]

Calculating IQR

[tex]IQR = Q_3 - Q_1[/tex]

[tex]Data: 1, 2,3,4,10[/tex]

In (a), we calculate the median as:

[tex]Median=3[/tex]

First, we calculate [tex]Q_1[/tex]

[tex]Q_1 = Median\ of\ the\ first\ half.[/tex]

The first half is:

[tex]First\ Half = 1,2,3[/tex]

So:

[tex]Q_1 = 2[/tex]

First, we calculate [tex]Q_3[/tex]

[tex]Q_3 = Median\ of\ the\ second\ half.[/tex]

[tex]Second\ Half = 3,4,10[/tex]

So:

[tex]Q_3 = 4[/tex]

Recall that:

[tex]IQR = Q_3 - Q_1[/tex]

[tex]IQR = 4 - 2[/tex]

[tex]IQR = 2[/tex]

So, we have:

[tex]IQR = 2[/tex]

[tex]SD = 3.2[/tex]

By comparison, the standard deviation is greater than the IQR because:

[tex]3.2 > 2[/tex]

So,

[tex]SD> IQR[/tex]

Answer:

Y=70

X=110

Step-by-step explanation:

if the inside of a triangle equals 180, than 70 plus 40 equals 110 which mean Y =70. if a straight line eguals 180 as well 180-70= 110 X= 110

Step-by-step explanation:

Answer:

the correct answer is 257

Answer: a. Total cost = 3g+2

b. The total cost of 8 games is $26.

Step-by-step explanation:

Given: Cost to bowl a game = $3

Shoe rental charge = $2  (One -time charge)

Total cost = (Cost to bowl a game) x (Number of games)+ (Shoe rental charge )

Let g= number of games, then the expression to find the total cost will be :

Total cost = 3g+2

To find the total cost of 8 games, put g=8, we get

Total cost = 3(8)+2

= 24+2 = $26

Therefore , the total cost of 8 games is $26.

Step-by-step explanation:

Answer:

x=12

Step-by-step explanation:

since they are supplementary they will have a sum of 180 degrees

The equation should look like this- (5x+4)+(4x+80)=180

after solving the equation- you get x=12

in order to see if that is correct you would plug in 12 where x is in our equation (5x+4)+(4x+80). which does equal 180 when 12 is plugged in

Therefore, 12 is your answer

Answer:

88

Step-by-step explanation:

First we do what is inside the parenthesis:

(6+2)=8

Then we do:

[tex]8^{2}[/tex]=64

So:

[tex]14+[64 + 10][/tex]

Then we do brackets:

14+{74}

Then we add:

88

Answer: 88

Step-by-step explanation:

    14 + ((6 + 2^)2 + 10)

Remove parentheses.

    14 + (6 + 2)^2 + 10

Simplify each term.

Add 6 and 2.

    14 + 8^2 + 10

Raise 8 to the power of 2.

    14 + 64 + 10

Simplify by adding numbers.

Add 14 and 64.

    78 + 10

Add 78 and 10.

    88

Step-by-step explanation:

Given

Volume (V) = 313 in³

π = 3.14

Height (h) = 16 in

Radius (r) = ?

We know.,

Volume of cone (V)

[tex]313 = \frac{1}{3} \pi {r}^{2}h [/tex]

[tex]313 \times 3 = 3.14 \times 16 \times {r}^{2} [/tex]

[tex]939 = 50.24 {r}^{2} [/tex]

[tex]18.69 = r^{2} [/tex]

[tex]r = \sqrt{18.69} [/tex]

r = 4.32 in
