Answer:

180

Step-by-step explanation:

total ratio is 15

gallons of red =

[tex] \frac{12}{15} \times 6 \times \frac{15}{0.5 } \\ \\ = 144[/tex]

gallons of yellow

[tex]30[/tex]

gallons of blue

[tex] \frac{0.5}{15} \times 30 \times \frac{15}{2.5} \\ \\ = 6[/tex]

total =144+30+6

=180

Answer:

180

Step-by-step explanation:

Answer: 0.628

Step-by-step explanation:

Probability of U.S. smartphone owners have made an effort to limit their phone use in the past : p = 0.4702

Sample size : n= 54

Mean : [tex]\mu =(54)(0.4702)=25.39[/tex]

Standard deviation:

[tex]\sigma=\sqrt{(54)(0.4702)}=\sqrt{25.39}\\\\\approx5.039[/tex]

The probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past will be :

[tex]P(22\leq x\leq29)=P(21<x<30)=P(\dfrac{21-25.39}{5.039}<\dfrac{X-\mu}{\sigma}<\dfrac{30-25.39}{5.039})\\\\=P(-0.8712<z<0.914864)\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\=P(z<0.914864)-P(z<-0.8712)\\\\=P(z<0.914864)-(1-P(z<0.8712))\\\\=0.8198685-(1-0.8081775)\ \ \ [\text{ By p-value table}]\\\\=0.628046[/tex]

Hence, the required probability = 0.628

Step-by-step explanation:

Answer:

80.

Step-by-step explanation:

To find the mean of an amount of numbers, you first add up all of the numbers, in this case, 90 + 80 + 70 = 240. Then, you simply divide the sum of all the numbers by the amount of numbers there are. In this case, there are three. (90, 80, and 70). So to find your answer, the equation would be:

(90 + 80 + 70) ÷ 3 = 80.

Answer:

65

Step-by-step explanation:

Since 39 is equal to 60%, and 60% is also equal to 60/100, then 39/x (x is the total we are solving for) is equal to 60/100.

Cross multiply so 39/x = 60/100

39*100 = 60x

3900 = 60x (divide both sides by 60)

65 = x

The change would you owe them is : 2.528

We have the following information available from the question is:

A customer purchase aced items in your store totaling $12.64.

They hand you three $5.00 bills.

We have to find the how much change would you owe them?

Now, According to the question:

The change would you owe them is :

Then, Divide the store totaling bill is $12.64 by $5.00 bills.

We get :

=> $12.64 ÷ %5.00

=> 2.528

Answer: 118 combinations.

Step-by-step explanation:

In ALIVE we have 5 letters, rearranging it we have the possible options of:

5 options for the first letter.

4 options for the second letter, as one was already chosen for the first one

3 options for the third letter, as 2 were already chosen.

2 options for the fourth letter.

1 option for the last letter.

The total number of combinations will be equal to the product of the numbers of options for each letter, then we have:

5*4*3*2*1 = 120 combinations.

And the combinations where the word EVIL is formed are:

AEVIL

EVILA

2 combinations, then the total number of combinations such that the word evil is not formed are:

120 - 2 = 118 combinations.

Answer:

M = 165.66

Step-by-step explanation:

Given the proportion, [tex] \frac{M}{178} = \frac{188}{202} [/tex], gif ind the value of M, start by multiplying both sides by 178

[tex] \frac{M}{178} \times 178 = \frac{188}{202} \times 178 [/tex]

[tex] M = \frac{188 \times 178}{202} [/tex]

[tex] M = \frac{188 \times 178}{202} [/tex]

M = 165.66 (nearest hundredth)

Answer:

x = 134°

Step-by-step explanation:

Let

[tex]\angle A=64^{\circ}\\\\\angle B =70^{\circ}[/tex]

We need to find the value of x.

We can see from the figure that x is exterior angle. To find x we can use exterior angle theorem. According to this theorem,

[tex]x=\angle A+\angle B\\\\x=64+70\\\\x=134^{\circ}[/tex]

Hence, the value of x is 134°
