Answer:

C

Step-by-step explanation:

Since the reflection line is at y=1 then B is only one y value above that line. Therefore, B prime should be one y value below that line.

Answer:

Step-by-step explanation:

Kindly find a simple sketch of a baseball pitch, the circle with a dot inside represents the first base coach(don't mind my drawing please I will improve).      

So, from the diagram, we can see that the expression that describes the distance and the first base coach is

y=90+3

y=93

so the distance  between Roberto Clemente and the first base coach is 93ft

Answer: 8x⁴ - 12x³ - 176x² + 420x

Step-by-step explanation:

First multiply 4x by (x - 3) which = 4x² - 12x. Next multiply (4x² - 12x) by (x + 5) which = 4x³ + 8x² - 60x. Multilying our new trinomial with the next binomial: (4x³ + 8x² - 60x)(2x - 7) = 8x⁴ + 16x³ - 120x² - 28x³ - 56x² + 420x. Combining like terms: 8x⁴ - 12x³ - 176x² + 420x. Notice that when you reduce and factor, you will end up with the starting binomials meaning this solution is correct.

Given:

The sum of the first three terms of a sequence Is 42.

The fourth term is 24.

To find:

The  u₁ and the common difference

Step-by-step explanation:

nth term of a sequence is

[tex]u_n=u_1+(n-1)d[/tex]

where, u₁ is first term and d is common difference.

4th term is 24.

[tex]u_4=u_1+(4-1)d[/tex]

[tex]24=u_1+3d[/tex]           ...(i)

Sum of nth term of an AP is

[tex]S_n=\dfrac{n}{2}[2u_1+(n-1)d][/tex]

Sum of first three terms is 42.

[tex]S_3=\dfrac{3}{2}[2u_1+(3-1)d][/tex]

[tex]42=\dfrac{3}{2}[2u_1+2d][/tex]

Divide both sides by 3.

[tex]14=u_1+d[/tex]          ...(ii)

On subtract (ii) from (i), we get

[tex]10=2d[/tex]

[tex]5=d[/tex]

Put d=5 in equation (ii).

[tex]14=u_1+5[/tex]

[tex]14-5=u_1[/tex]

[tex]9=u_1[/tex]

Therefore, the first term is [tex]u_1=9[/tex] and common difference is [tex]d=5[/tex] .

Answer:

76; 20

Step-by-step explanation:

s = small room = 2

l = large room = 4

14s + 12l = 28 + 48 = 76

as I said before s = 2 and l = 4

s*s + l*l = 2*2 + 4*4 = 4 + 16 = 20

Answer:

14 small rooms and 12 large rooms: 76

"s" small rooms and "l" large rooms: 20

Step-by-step explanation:

14 small rooms and 12 large rooms:

Answer:

D. 45

Step-by-step explanation:

All angles have to = 180°

60 + 75 + <RVE = 180°

135 + RVE = 180°

180 - 135 = 45° RVE

RVE = 45°

Another way to check your answer:

Add all of the angles, and it should equal 180°

60 + 75 + 45 = 180°

Answer:

a) Please find the attached scatter plot

b) Y = 0.85·X + 51.843

c) The intercept = Sarah's height at birth

The slope = Sarah's monthly growth rate

d) Sarah's height in 50 years (600 months) will be 221.198 inches

d) The generality of the population stop growing taller when they reach 216 months old

Step-by-step explanation:

a) Please find attached the scatter plot included here

b) From Microsoft Excel, we have;

N = 6

(ΣX)² = 93636

ΣX = 306

ΣY = 569

ΣXY = 29325

ΣX² = 15966

The equation for the least squares regression line is Y = b·X + a

Where;

[tex]a = \dfrac{\sum Y - b\sum X}{N}[/tex]

[tex]b = \dfrac{N\sum XY - \left (\sum X \right )\left (\sum Y \right )}{N\sum X^{2} - \left (\sum X \right )^{2}}[/tex]

Substituting the values, gives;

[tex]b = \dfrac{6 \times 29325- 306 \times 569}{6 \times 15966 - 93636} = 0.85[/tex]

[tex]a = \dfrac{569 - 0.85 \times 306}{6} = 51.48\bar 3[/tex]

The equation of the least squares regression line is Y = 0.85·X + 51.843

c) The intercept gives the Sarah's height at birth, while the slope gives the increase in Sarah's height every month

d) In 50 years, which is equivalent to 600 months, we will have;

Y = 0.85 × 600 + 51.843 = 561.843 cm

2.54 cm = 1 inches

Therefore;

561.843 cm = 561.843 cm/2.41 × inches/cm ≈ 221.198 inches (18.43317 feet)

Sarah's height in 50 years (600 months) = 221.198 inches

d) The reason for the impossibly large height is that the generality of the population stop growing taller by 18 years of age which is 216 months.

Step-by-step explanation:

∠1 = 61°

∠2 = 119°

∠3 = 61°

∠4 = 119°

∠5 = 119°

∠6 = 61°

∠7 = 119°

-------------------------------

∠1 = 61°   = as given

∠2 = 119° = ( 180 - 61 ) = 119°

∠3 ≅ ∠1  opposite angles are equal (congruent)

∠4 ≅ ∠2  opposite angles are equal (congruent)

∠5 ≅ ∠2 or parallel

∠6 ≅ ∠3 ≅ ∠1

∠7 ≅ ∠5

-x12 + x7 = 0

Factorization:

−x7(x − 1)(x4 + x3 + x2 + x + 1) = 0

Solutions based on Jenkins–Traub algorithm:

x1 = … = x7 = 0

x8 = 1

x9 = −0.809017 − 0.587785i

x10 = −0.809017 + 0.587785i

x11 = 0.309017 − 0.951057i

x12 = 0.309017 + 0.951057i

Step-by-step explanation:

Cost = $112

30% discount coupon on the item he's going to buy

=$112 × 30/100 (or you can write 30%)

=$168/5 ($33.6)

7% tax on the item=$112 × 7/100(or you can write 7%)

= $196/25 ($7.84)

Total amount altogether=$112 - $33.6 - $7.84

Step-by-step explanation:

cause intgetables it goes up by six on each one

Answer:

12%

Step-by-step explanation:

Step 1

We find the standard deviation

A randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean.

Mean = 33mg

35 = Mean - 1.2(standard deviation)

35 = 33 + 1.2(standard deviation)

35 - 33 = 1.2(standard deviation)

2 = 1.2(standard deviation)

Standard deviation = 2/1.2

= 1.6666666667

= 1.67

Therefore, the standard deviation is 1.67

Step 2

Using the z score formula

Z score = x - μ/σ

x = 35mg

μ = mean = 33mg

σ= standard deviation = 1.67

= 35 - 33/1.67

= 1.1976

Probabilty value from Z-Table:

P(x<35) = 0.88446

P(x>35) = 1 - P(x<35)

= 1 - 0.88446

= 0.11554

Converting to percentage = 0.11554 × 100

= 11.554%

≈ 12%

Therefore, the percent of 8-ounce cans of the cola having a caffeine content greater than 35mg is approximately 12%

Using the normal distribution, it is found that 11.5% of 8-ounce cans of the cola have a caffeine content greater than 35mg.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, a randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean, which means that the z-score is Z = 1.2.

The percent of 8-ounce cans of the cola have a caffeine content greater than 35mg is 1 subtracted by the p-value of Z = 1.2, so:

Looking at the z-table, Z = 1.2 has a p-value of 0.885.

1 - 0.885 = 0.115

11.5% of 8-ounce cans of the cola have a caffeine content greater than 35mg.

Answer:

Step-by-step explanation:

If B is the midpoint of AC, then AB = BC  and AB+BC = AC

AB +AB = AC

2AB = AC

2(2x+12) = 10x-12

4x+24 = 10x-12

collect like terms:

4x-10x = -12-24

-6x = -36

x = -36/-6

x = 6

Get AB:

AB = 2x+12

AB = 2(6)+12

AB = 12+12

AB = 24

Since AB = BC, hence BC = 24

AC = AB+BC

AC = 24+24

AC = 48
