graph g(x)= -1/2f(x+2)

Answer:

simple - 1/21 chance

Step-by-step explanation:

since its asking for the probability of "a" marble, and not all the green marbles, you add everything up and slap what outcome (1 in this case) on top of the 21

here is cat

Answer:

3 is for green marbles

21 is the total of all marbles

Step-by-step explanation:

you only have 1 event so I think we don't need some formula or something

the formula is this if the event A and B has no intersection P( A U B)= P(A)+P(B)

and if it has intersection, the formula is like this P( A ∩ B)=P(A)+P(B)-P( A ∩ B)

55 + 20

Answer:

5(x-1) = 17

5x - 5 = 17 (write equation in simpler terms)

add 5 on each side like this (5x = 17 + 5)

= 5x = 22 which results in 4.4

Answer:

The answer is "H [93%, 100%]"

Step-by-step explanation:

I'll edit this in a second to show the process, but it may take a minute. Just have the answer for now.

This is a surprisingly useful question hah, I'll bet many will need to do this.

This question is just finding the average. Pretty simple.

y = 86 + 82 + 91 + 98 + x / 5

y = 357 + x / 5

An easy way is to do the lowest question first, then go from lowest to second lowest and so on. Because if you go to the highest one and the answer is one of the lower ones, well, of course it's going to be within the 90-100 range, but that doesn't necessarily mean it's the answer.

y = 357 + (87) / 5

y = 444 / 5

y = 88.8

Okay, so the answer isn't G. Then let's try H.

y = 357 + (93) / 5

y = 450 / 5

y = 90

Yep, the answer is H. This is because it equals 90, which is indicative of the 90-100% range that Latoya needs to get an "A".

Answer:

50

Step-by-step explanation:

if 50 degrees is the angle across from b, then 50 is b. 50 applies to b as well. whatever is across from it is the same thing. all of the angles should add up to 360 at an intersection.

Answer:

5 lollies are left over

Step-by-step explanation:

Total lollies Jordan has = 47

Number of boys at the party = 6

If the lollies are shared equally,

Number of lollies each boy gets = Total lollies ÷ number of boys

= 47 ÷ 6

= 7 lollies remainder 5

That is,

6 boys × 7 lollies each = 42 lollies

How many lollies were leftover.

Remaining lolly = Total lollies - shared lollies

= 47 - 42

= 5 lollies are left over

Answer:

46.20

Step-by-step explanation:

First determine how much he earned:

8.8 per hour times 7 hours

8.80 *7 =61.60

Then determine how much he gave his mother

61.60 * 1/4 =15.4

Subtract this from the total amount to determine how much is left

61.60-15.40

46.20

Answer:

using pythagoras theorem

a^2+b^2=c^2

8^2+x^2=(x+2)^2

64+x^2=x^2+2*x*2+2^2

64+x^2=x^2+4x+4(here x^2 of left hand side and x^2 of right hand side gets cancel)

64=4x+4

64-4=4x

60/4=x

Answer:

10.9

Step-by-step explanation:

The "mean" is just school's fancy way of saying "the average". To find the mean of the numbers, you add them all up first. 12 + 5 + 14 + 6 + 17 + 7 + 15 = 76. The next step is to divide 76 by the number of values that were added. 12, 5, 14, 6, 17, 7, and 15 are a total of 7 numbers. So, we will divide 76 by 7.

76/7 = 10.8571428571, which rounds to 10.9 if you are rounding it to the nearest tenth.

Answer:

[tex]\boxed {\boxed {\sf 10.9 \ hours }}[/tex]

Step-by-step explanation:

The mean is also called the average. It is a measure of central tendency and provides information about the center of a data set.

The mean is found by adding up all the values, then dividing by the number of values. Remember, this is the data set we have:

12, 5, 14, 6, 17, 7, 15

1. Add up values

12 + 5+ 14 + 6 + 17 + 7 + 15= 76

2. Divide by the number of values

76/7=10.8571428571

3. Round

10.8571428571 ≈ 10.9

The mean number of hours spent watching television for this group of students is 10.9 hours.

Answer: 40%

Step-by-step explanation:

There are four red marbles and six blue marbles, so there is a total of 10 marbles. Since four of those marbles are red, there is a 4 in 10 chance to select a red marble, or 4/10. 4/10 equals 0.4 which in terms of percentage is 40% (multiply by 100).

Answer:

Explanation:                                      Equivalent:

6 x 5x, 6 x -3                                        30x - 18

Combine like terms,  (8 + 6) (10x)       10x - 14

8 - (-6) (10x)                                           10x - 14      

8 -(-6) (-10x)                                          -10x - 14      

(2 x -5x = -10x) (2 x 7 = 14)                    2(-5x + 7)                                          

Answer:

y = -5x + 3.

Step-by-step explanation:

We can find the point of intersection by solving the system:

y = 2x + 3  ....  1

x + y = 3   ......  2          from this:

y = 3 - x   ....... .3

Equating equations 1 and 3:

2x + 3 = 3 - x

3x = 0

x = 0 so y = 2(0) + 3 = 3.

So the point of intersection is (0, 3).

So the required equation has slope -5 and passes through (0, 3) and,  using the point-slope form of a straight line, we have:

y - 3 = -5(x - 0)

y - 3 = -5x

y = -5x + 3.

According to the question,

We are asked to calculate how much money will I have in 2 days.

If in one day, I work 12 hours, so

→ Total hours I'll work in 2 days = 2(12) hours

→ Total hours I'll work in 2 days = 24 hours

Also, in the question it is given that,

→ Earnings I get for working an hour = $21.30

→ Earnings I'll get for working 24 hours = $(21.30 × 24)

→ Earnings I'll get for working 24 hours = $511.2

Therefore, I'll have $511.2 in two days.

Answer:

Earning per hour = $21.30

No. of hours he works = 12 hours

So in two days no. of hours he work = (12×2) hours = 24 hours

He earned in two days = 24 × $21.30 = $ 511.20 ( ans)

Answer:

B.) -9

Step-by-step explanation:

The value of b if 3/2 is the axis of symmetry for the graph of the function f(x)=3x2+bx+4 is -9

The standard equation of a function in vertex form is given as:

f(x) = (a + x)^2 + h

Given the function f(x)=3x^2+bx+4 with an axis of symmetry of 3/2, the vertex is expressed as:

3/2= -b/2a

-b/2(3)=3/2

-b/6=3/2

Cross multiply

-2b = 18

-b=9

Hence the value of b if 3/2 is the axis of symmetry for the graph of the function f(x)=3x2+bx+4 is -9

Complete Question:

Every Thursday, Matt and Dave's Video Venture has "roll-the-dice" day. A customer may choose to roll two fair dice and rent a second movie for an amount (in cents) equal to the numbers uppermost on the dice, with the larger number first. For example, if the customer rolls a two and a four, a second movie may be rented for $0.42. If a two and a two are rolled, a second movie may be rented for $0.22. Let X represent the amount paid for a second movie on roll-the-dice day. The expected value of X is $0.47 and the standard deviation of X is $0.15

Answer:

0.14

Step-by-step explanation:

Given that :

Expected value = 0.47

Standard deviation = 0.15

Sample size, n = 30

The mean = expected value * sample size

Mean = 0.47 * 30 = 14.1

Standard deviation of sample = σ / √n

0.15 = σ/√30

σ = 0.8216

P(x > 15) :

Z = (x - mean) /standard deviation

Z = (15 - 14.1) / 0.8216 = 1.095

P(Z > 1.095) = 0.1367

P(Z > 1.095) = 0.14
