Which of the following equals 5.96?

A. 2.98 + 2.89
B. 0.6 + 5.9
C. 6.03 + 0.07
D. 1.061 + 4.899

Step-by-step explanation:

[tex]g(f(8)) =( n ^{2} - n )+ 1 = 8 ^{2} - 8 + 1 = 64 + 9 = 73[/tex]

Answer:

Time in hours (x) ==> distance in miles (y)

1 ==> 610

2 ==> 1,220

2.5 ==> 1,525

Note: constant of proportionality is same all through = 610

Step-by-step explanation:

Constant of proportionality = [tex] \frac{y}{x} = \frac{915}{1.5} = 610 [/tex]

To get the y-values (miles) for each given x-value (hours), multiply each x-value by the constant of proportionality, 610. Constant of proportionality is same all through.

Thus,

Time in hours (x) ==> distance in miles (y)

1 ==> 1*610 = 610

2 ==> 2*610 = 1,220

2.5 ==> 2.5*610 = 1,525

Answer:

7kg:1kg=7:1 itself

Because 7 and 1 has one '1' as a common factor, so they can't be simplified

Answer: the answer is -23 i think

Step-by-step explanation:

Answer:

230

Step-by-step explanation:

The answer is 230 because if you add 123 and 108 together you get 231 but since we are rounding to the nearest 10 it would be 230 because 231 is closer to 230 than it is to 240.

Answer:

12

Step-by-step explanation:

if 8+15 is about the length of the circle, the length is about 23

so 23 - 10 = 13 and the closest number to 13 is 12 so 12 is the answer

Answer:

The number of liters for container R = x = 0.5 liters

The number of liters for container S = y = 1.5 liters.

Step-by-step explanation:

Let the number of liters of container R = x

Let the number of liters of container S = y

We are told in the question : that

Container R holds a solution that is 20% alcohol

= 20% × x = 0.20x

Container S holds a solution that is 60% alcohol.

= 60% × y = 0.60y

How many liters of solution from each container should be used to create 2 liters of solution that is 50% alcohol?

Hence;

x + y = 2 ....... Equation 1

x = 2 - y

0.20x + 0.60y = 2 × 50%

0.20x + 0.60y = 1........ Equation 2

Substitute

2-y for x in Equation 3

0.20(2 - y) + 0.60y = 1

0.40 - 0.20y + 0.60y = 1

Collect like terms

0.40y = 1 - 0.40

0.40y = 0.60

y = 0.60/0.40

y = 1.5 liters

Note that :

x = 2 - y

x = 2 - 1.5

x = 0.5 liters

Therefore,

the number of liters for container R = x = 0.5 liters

the number of liters for container S = y = 1.5 liters.

Answer: -8

Step-by-step explanation:

R= a2/a1

32/-4 divide by 4 to simplify so its -8

-4*-8= 32

32*-8 = -256

Answer:

(a) [tex]\text{P(n)} = \text{p} \times \text{(1 - p)}^{n-1} ; \text{ n} = 1, 2, 3,....[/tex]

(b) P(1) = 0.740, P(2) = 0.192, and P(3) = 0.050.

(c) The probability that n ≥ 4 is 0.018.

(d) The expected number of residents in the village you must meet before you encounter the first person of Hawaiian ancestry is 3.

Step-by-step explanation:

We are given that on the leeward side of the island of Oahu, in a small village, about 74% of the residents are of Hawaiian ancestry.

Let n = 1, 2, 3, … represent the number of people you must meet until you encounter the first person of Hawaiian ancestry in the village.

(a) We can observe that the above situation can be represented through the geometric distribution because the geometric distribution states that we will keep on going with the trials until we achieve our first success,

Here also, n represent the number of people you must meet until you encounter the first person of Hawaiian ancestry in the village.

So, the probability distribution of the geometric distribution is given by;

[tex]\text{P(n)} = \text{p} \times \text{(1 - p)}^{n-1} ; \text{ n} = 1, 2, 3,....[/tex]

where, p = probability that the residents are of Hawaiian ancestry = 74%

(b) The probabilities that n = 1, n = 2, and n = 3 is given by;

[tex]\text{P(n)} = \text{p} \times \text{(1 - p)}^{n-1}[/tex]

P(1) = [tex]\text{0.74} \times \text{(1 - 0.74)}^{1-1}[/tex] = 0.74

P(2) = [tex]\text{0.74} \times \text{(1 - 0.74)}^{2-1}[/tex] = 0.192

P(3) = [tex]\text{0.74} \times \text{(1 - 0.74)}^{3-1}[/tex] = 0.050

(c) The probability that n ≥ 4 is given by = P(n ≥ 4)

     P(n ≥ 4) = 1 - P(n = 1) - P(n = 2) - P(n = 3)

                   = 1 - 0.74 - 0.192 - 0.050

                   = 0.018

(d) The expected number of residents in the village you must meet before you encounter the first person of Hawaiian ancestry is given by = E(n)

We know that the mean of the geometric distribution is given by;

           Mean = [tex]\dfrac{p}{1-p}[/tex] = [tex]\dfrac{0.74}{1-0.74}[/tex]

                     = [tex]\dfrac{0.74}{0.26}[/tex] = 2.85 or 3 (approx).

Answer:

3960 feet

Step-by-step explanation:

Answer:

3,960 feet long

Step-by-step explanation:

1 mile = 5,280 feet

5,280 feet ÷ 4 (because the denominator is 4) = 1,320 feet

1,320 x 3 (the numerator is 3) = 3,960 feet

3/4 of a mile = 3,960 feet

Answer:

[-7,2]

Step-by-step explanation:

the range is all the possible y-values, and the highest point of the graph is at (-3,2) while the lowest is at (0,-7). when looking at the y-coordinates, we realize that the range is [-7,2] (brackets because those points are included).

Answer:

  A = 12

Step-by-step explanation:

  [tex]48\%=\dfrac{48}{100}=\dfrac{4\cdot12}{4\cdot25}=\boxed{\dfrac{12}{25}}[/tex]

Comparing this to A/25, we see that A = 12.

Answer:

I believe that number 7 is true.

Step-by-step explanation:

8. Is not a vertical angle because 3 and 3 do not look the same. The line is clearly gone on one side.

9. Is also wrong because both angles do not make a 90 degree angle.

10. Is wrong because both angles make a 90 degree angle when it should make a be 180 degrees.

( I'm learning this subject right now so it might be wrong. Tell me if I go this right.)

A -120 difference will be seen in the temperature within a 7 hour period

Equation

Multiplying two of different signs ( - + ,  + - ) will always be negative.

Multiplying two of the same sign ( - - , + + ) will always be positive.

Answer:

105 min

Step-by-step explanation:

60 minutes ÷ 4 miles= 15 minutes per mile

15min per mile x 7 miles = 105 minutes

Answer:

5 small beads!

Step-by-step explanation:

Hey there!

If large beads are $3 each, and she buys 5 of them, our equation is $3 x 5 which equals $15. So Cara will spend $15 buying large beads.

Cara has $10 left now, because $25 - $15 = $10. Since each small bead is $2, we divide $10 (the total amount of money she has) by $2 (the cost of each bead). This will tell us how many she can buy! So $10 ÷ $2 is 5. Cara can buy 5 small beads!

I hope this helped you! Rating my answer and giving it a Thanks would sure help me out!

Have a wonderful day!

Answer: It’s unfinded

Step-by-step explanation:

Answer: 55

Step-by-step explanation:

just add 41.5 on 13.5 and that is x

Answer: X=55

Step-by-step explanation:

First, you want to move the constant, -41.5, to the right-hand side and change the sign. You now have an equation of x=13.5+41.5.

You are now going to add 13.5 and 41.5, getting 55, which is your answer. Hope this helps!
