Tony has begun to save money to buy a new video game. At the end of the first week, he has $8 in his savings. At the end of the second week he has $11 in savings, and after the third week he has $14.
Tony feels confident that he can continue this same pattern of saving money to buy the game.
Which function describes the sequence?

Answer:

23

Step-by-step explanation:

89+150+67+(2y+8)=360

2y+8=54

2y=46

y=23

Answer:

Given that the manufacturers claim is true, the probability that the sample mean area is 249.6 ft.² or less is 0.42074

Step-by-step explanation:

The manufacturer claims that mean amount of foil on each roll, μ = 250 ft²

The standard deviation of the measured amount of foil per roll, σ = 2 ft.²

The number of rolls tested by the restaurant, n = 10 rolls

The mean measured by the restaurant, [tex]\overline x[/tex] = 249.6

Taking the sample means as individual score, we have;

The z-score, of the sample mean is given as follows;

[tex]z=\dfrac{\overline x -\mu }{\sigma }[/tex]

At [tex]\overline x[/tex] = 249.6, we have;

z = (249.6 - 250)/2 = -0.2

Therefore, the probability for a mean less than or equal to 249.6, we have;

The probability, P = P(z < -0.2) = 0.42074

The probability that the sample mean area is 249.6 ft.² or less given that the manufacturers claim is true, P = 0.42074.

Answer:

Area is 1246

Step-by-step explanation:

39 x 34 - 10 x 8

Answer:

You answer would be option B

Step-by-step explanation:

You would have to open parenthesis/distribute 4 by multiplying it by x and 8 which are inside the parenthesis.

Answer:

4.375 yards of wood

Step-by-step explanation:

You would do 5/8 time 7/1. Then you would do 5 times 7 and get 35. Then you'd do 8 times 1, which equals 8. 35/8 is equivalent to 4.375

Answer:

the answer is 3 to 2...........

Original price of jeans=$50

Since there is a discount of 30%

So we take 100%-30%=70%

hence to find the price Justin have to pay after discount, we take $50x70/100=$35

Therefore Justin has to pay $35 for the jeans after discount.

this equation is unanswerable, there is no way to find x.

Answer:

About 9-10 weeks

Step-by-step explanation:

70/7= 10

Answer:

9-10

Step-by-step explanation:

Answer:

Third choice

Step-by-step explanation:

Add and subtract like terms:

-2xy - 6xy = -8xy

-8y - 2y = -10y

-4y^4 + y^4 = -3y^4

Combine them together, and you get:

-3y^4 - 8xy -10y

Answer:

3)

Step-by-step explanation:

1. Remove brackets

2.  add like terms (-8y and 2y)

3. copy the un-addble terms behind

Answer:

0.25

because sum of probabilities is always equal to 1

i.e P(sean doesn't miss the bus)+P(sean misses the bus)=1

P(sean misses the bus) = 1-0.85 =0.25

Answer:

B x=60, y=60

Step-by-step explanation:

The triangle should equal 180 in total. It shows 60 already on top then you would add them all up 60+60+60=180 degrees.

Answer:

B

Step-by-step explanation:

x=60 and y=60.

Answer: The arc length of the clock is 31.42cm

Step-by-step explanation:

1. Use your section formula: S = r (Radius) θ (Theta: Angle in radians)

2. Convert your 180 degrees to radians by multiplying it by π / 180, resulting in π radians.

3. Take your radius of 10cms and multiply it by π, leaving 31.42cm. This is the length of the 180 degree arc.

Answer:

a₇ =  2.375

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

r = [tex]\frac{-76}{152}[/tex] = [tex]\frac{38}{-76}[/tex] = [tex]\frac{-19}{38}[/tex] = - [tex]\frac{1}{2}[/tex]

This indicates the sequence is geometric with nth term

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 152 and r = - [tex]\frac{1}{2}[/tex] , then

[tex]a_{n}[/tex] = 152 [tex](-\frac{1}{2}) ^{n-1}[/tex] , so

a₇ = 152 [tex](-\frac{1}{2}) ^{6}[/tex] = 152 × [tex]\frac{1}{64}[/tex] = 2.375

Answer:

Solution given:

first term [a]=152

second term[b]=-76

common ratio[r]=[tex] \frac{-76}{152}[/tex]=-1/2

now

for nth term ,we have

nth term =a [tex] {r}^{n -1} [/tex]

now

7th term==152[tex] {-1/2}^{7 - 1} [/tex]

=152×1/64=19/8

Answer:

Step-by-step explanation:

Note how this drawing  is symmetrical about a horizontal line drawn halfway between AB and CD and passing through the origin.

Line AB has been subdivided into two equal pieces of length 15, so the length of AB is twice 15, or 30.  Due to the symmetry shown, line CD has the same length:  30.

Step-by-step explanation:

Answer:

c = 2, d = - 3

Step-by-step explanation:

Expand and simplify the left side then compare the coefficients of like terms on both sides.

5(2x + 1) + c(x + d) ← distribute parenthesis

10x + 5 + cx + cd

= x(10 + c) + 5 + cd

Compare like terms on both sides, that is

10 + c = 12 ( subtract 10 from both sides )

c = 2

Then

5 + cd = 5 + 2d and

5 + 2d = - 1 ( subtract 5 from both sides )

2d = - 6 ( divide both sides by 2 )

d = - 3

Answer:

c) 50

Step-by-step explanation:

√36 + 2 * 5^2  - 6

√36 = 6, 5^2 = 25

6 + 2 * 25 - 6 = 25 2 * 25 = 50, 6 + 50 - 6, 50
