Answer:

if I understand correctly, I hope this helps:

Answer to b: a< or equal to Zero.

Answer to d: a>or equal to -5

Answer:

Step-by-step explanation:

Consecutive terms in this sequence are separated by a constant c, so if the 4th term is 15, then the next terms would be

5th: 15 + c

6th: (15 + c) + c = 15 + 2c

7th: (15 + 2c) + c = 15 + 3c

and so on. More generally, since any given number in the sequence depends on the number that came before it, we can write the n-th term in terms of the 4th term,

n-th: 15 + (n - 4) c

Then the 9th term in the sequence is

15 + (9 - 4) c = 35

and solving for c gives

15 + 5c = 35   ==>   5c = 20   ==>   c = 4

Then the 15th term would be

15 + (15 - 4)×4 = 15 + 11×4 = 15 + 44 = 59

Explanation:

Segment AB is already given to be 19 miles long.

I'm assuming your teacher meant to ask about side BC, which is side 'a' since it's opposite angle A.

Use the law of cosines to find the missing side

a^2 = b^2 + c^2 - 2*b*c*cos(A)

a^2 = 12^2 + 19^2 - 2*12*19*cos(138)

a^2 = 843.874040417691

a = sqrt(843.874040417691)

a = 29.0495101579647

a = 29 when rounding to the nearest whole number

Side BC is roughly 29 miles long.

Answer:

Point of intersection:

[tex]3x - y = 8 - - - (a) \\ x + 2y = 5 - - - (b) [/tex]

2 × equation(b) + equation (a):

[tex]7x = 21 \\ x = 3 \\ \\ y = 3x - 8 \\ y = 1[/tex]

Point of intersection = (3, 1)

Perpendicular line:

[tex]3x + 6y - 11 = 0 \\ 6y = - 3x + 11 \\ y = - \frac{1}{2} x + \frac{11}{6} [/tex]

General equation of line:

[tex]y = mx + c \\ 1 = (2 \times 3) + c \\ c = - 5[/tex]

Value of m:

[tex]m \times m {}^{i} = - 1 \\ m \times - \frac{1}{2} = - 1 \\ m = 2[/tex]

ans: 257,256.59

if it was sold for $3.99

it would have been 86,047 × $3.99 = 343,303.59 and it was sold for $1 instead so automatically it's $86,047

therefore

343, 303.59

-86, 047 which is equal to a loss of $257, 256.59

Answer:

1006

Step-by-step explanation:

Take proportion, p = 62%

n = (Z² * pq) / M.E²

Margin error = 0.03

p = 62% = 0.62

q = 1 - p = 1 - 0.62 = 0.38

Zcritical at 95% = 1.96

n = (1.96² * (0.62*0.38)) / 0.03²

n = 0.90508096 / 0.0009

n = 1005.6455

n = 1006

Sample size = 1006

Step-by-step explanation:

It's an isosceles triangle because 2 sides  are congruent ( 2 are 23 yds long).

The population is all one year-old boys.

This question uses the concepts of sample and populations.

After the explanation of these concepts, we have that:

Sampling:

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and expand this to the entire population of New York State residents, which is the population of the study.

In this question:

Study of mean weight of one-year old boys, sample of 360 randomly chosen one year-old boys. Thus, the population of interest is given by all one year-old boys.

Answer:

y = 3(x-1)^2 -3

Step-by-step explanation:

y = 3(x+5)^2 - 2

vertex: (-5, -2)

1 unit down :

-2 - 1 = -3

6 units to the right:

3(x+5-6)^2 -2

3(x-1)^2 - 2

make what's in the parenthesis equal to 0:

(x-1)^2 = 0

x = 1

or

-5 + 6 = 1

new vertex : (1, -3)

equation : y = 3(x-1)^2 -3

Translation involves shifting of points from one position to another. The equation of the new parabola is: [tex]y = 3(x - 1)^2 - 3[/tex]

Given that:

[tex]y = 3(x + 5)^2 - 2[/tex]

[tex](h,k) = (-5,-2)[/tex] --- vertex

The general equation of a parabola is:

[tex]y = a(x - h)^2 + k[/tex]

By comparison:

[tex]a = 3\\ h = -5 \\ k= -2[/tex]

When the vertex is shifted 1 unit down, the rule is:

[tex](x,y) \to (x,y-1)[/tex]

So, we have:

[tex](x,y) \to (-5,-2-1)[/tex]

[tex](x,y) \to (-5,-3)[/tex]

When the vertex is shifted 6 unit right, the rule is:

[tex](x,y) \to (x + 6,y)[/tex]

So, we have:

[tex](h,k) \to (-5 + 6,-3)[/tex]

[tex](h,k) \to (1,-3)[/tex]

This means that:

[tex]h = 1\\ k =-3[/tex]

Recall that:

[tex]a =3[/tex]

Substitute these values in:

[tex]y = a(x - h)^2 + k[/tex]

[tex]y = 3(x - 1)^2 - 3[/tex]

Hence, the equation of the new parabola is: [tex]y = 3(x - 1)^2 - 3[/tex]

Answer:

Step-by-step explanation:

We are finding the probability, which is a percentage, of each of these intervals on our standard bell curve. In order to find this percentage, we need to find the z-score that provides this percentage. To find the z-score:

[tex]z=\frac{x_i-\bar{x}}{\sigma}[/tex] which is the number in question minus the mean, all divided by the standard deviation. We're first looking for the probability that the gas mileage on a certain model of car is less than 26 mpg.

To find this z-score:

[tex]z=\frac{26-28}{4}=-.5[/tex] Depending upon which table you look at for the z-score determines how you will find it. The z-score that measure from the value and to the left of it is what we need. This decimal is .3085375, or 30.8538%.

Onto b., which is for the percentage of cars that have gas mileage over 34 mpg. Find the z-score, and this time, we look to the right of the value for the percentage:

[tex]z=\frac{34-28}{4}=1.5[/tex] and to the right of 1.5 standard deviations we will find .0668072, or 6.68072%

Then finally c., which wants the probability that the gas mileage on one of these cars is greater than 22 but less than 34 mpg. To do this we have to find the z-scores of each and then do some subtracting. First the z-scores:

[tex]z=\frac{22-28}{4}=-1.5[/tex] The percentage of data that lies to the right of that z-score is .9331927

The z-score for the other value, 34, was already found as 1.5, having .0668072 of the data to the right of that z-score. We subtract the smaller from the larger to determine what's left in-between:

.9331972 - .0668072 = .86639, or as a percentage, 86.639% of the cars fall into this interval for gas mileage.
