Complete question :

A study was done to investigate the population of bald eagle breeding pairs over time. The correlating regression model is shown

below, wiere x represents the number of years after 1986, and y represents the number of bald eagle breeding pairs. Interpret the y-

intercept

y = 1.772 +334x

Answer:

B. There were approximately 1.772 eagle breeding pairs in 1986

Step-by-step explanation:

Given the regression equation : y = 1.772 +334x

Recall the general form of a linear regression equation :

y = mx + c

y = predicted variable ; x = predictor Variable ; c = intercept ; m = slope

x = number of years after 1986 ; y = number of bald eagle pairs.

The intercept is a constant value at time t = 0

For x to be 0, on a graph, this this the value on the y axis where the regression line crosses the y - axis. That is in 1986; the number of y when in 1986 when x = 0 is 1.772

Answer:

3 3/18

Step-by-step explanation:

5 3/6-2 1/3

We first need to turn our mixed numbers into fractions by multiplying the while number by the denominator, then adding the numerator. When we do this, 5 3/6 turns into 33/6 and 2 1/3 turns into 7/3. Now we have this:

33/6-7/3

Now we need to find the Least common multiple of the denominators in order to find our common denominator, which in this case is 6. 33/6 already has a denominator of 6, so we do not need to do anything to it. To give a denominator of 6 to 7/3, however, we must multiply by 2, giving us this:

33/6-14/6

Now we can subtract the numerators.

19/6

To turn this back into a mixed number, we divide 19 by 6, which gives us 3 with a remainder of 1. Therefore, our answer is 3 1/6. This is an equivalent fraction to the fourth answer, 3 3/18.

Where:

h and k represents the vertex.

Also, the standard equation of a regular parabola is given by:

y = x²/4a

Note: The vertex for this parabola is at the origin (0, 0).

At what angle does a diffraction grating produce a second-order maximum for light having a first-order maximum at 20.0 degrees?

Answers

Answer:

At 43.2°.

Step-by-step explanation:

To find the angle we need to use the following equation:

[tex] d*sin(\theta) = m\lambda [/tex]

Where:

d: is the separation of the grating

m: is the order of the maximum

λ: is the wavelength

θ: is the angle              

At the first-order maximum (m=1) at 20.0 degrees we have:

[tex] \frac{\lambda}{d} = \frac{sin(\theta)}{m} = \frac{sin(20.0)}{1} = 0.342 [/tex]

Now, to produce a second-order maximum (m=2) the angle must be:

[tex] sin(\theta) = \frac{\lambda}{d}*m [/tex]

[tex] \theta = arcsin(\frac{\lambda}{d}*m) = arcsin(0.342*2) = 43.2 ^{\circ} [/tex]

Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.    

I hope it helps you!

Kai sells a small magazine full of celebrity gossip to college students for $2.65 per copy. Hiring the printing press for one day, the only fixed cost, is $435 an issue. The variable cost of printing each issue is $0.82 per copy. The printer tells Kai the cost of hiring the press is to increase by $116 per day. If changing to color increases variable costs by $0.40, what is the percentage decrease in contribution margin resulting from the switch to color?

Answers

Answer:

Percentage decrease= 21.86%

Step-by-step explanation:

Giving the following information:

Selling price per unit= $2.65

Current variable cost= $0.82

Increase in variable cost= $0.4

To calculate the unitary contribution margin, we need to use the following formula:

Unitary contribution margin= selling price - unitary variable cost

Unitary contribution margin= 2.65 - 0.82

Unitary contribution margin= $1.83

New contribution margin= 2.65 - 1.22

New contribution margin= $1.43

Finally, the percentage decrease:

Percentage decrease= [1 - (1.43/1.83)]*100

Percentage decrease= 21.86%

Mae ling earns a weekly salary of 400 plus a 6.5 commission on sales at a gift shop how much would she make in a work week if she sold 4300 worth of merchandise

Answers

Answer:

Mae Ling will make $679.5 in a week if she sells 4300 worth of merchandise.

Step-by-step explanation:

Given that

Weekly salary of Mae Ling = $400

Commission rate = 6.5%

Mae ling's total weekly earning will be her salary plus her commission on the sales she does in the week.

Given that her sales for the said week are: $4300

Her commission will be:

[tex]Commission = 6.5\%\ of\ sales\\ = 0.065*4300\\=\$279.5[/tex]

Now to calculate her total salary, we will add the weekly salary and commission.

[tex]Total\ weekly\ Earning = Weekly\ Salary +\ Commission\\= \$400+\$279.5\\=\$679.5[/tex]

Mae Ling will make $679.5 in a week if she sells 4300 worth of merchandise.

your slope is 3 so 3x

to find the y-intercept (b):

plug in y and x from either of the two points

(2,8)... 8=3(2)+b and solve for b which equals 2

Mixed in a drawer are 2 blue​ socks, 8 white​ socks, and 6 gray socks. You pull out two​ socks, one at a​ time, without looking. Find the probability of getting 2 socks of the same color.

Answers

Answer:

6/16

Step-by-step explanation:

Write them out bb wwwwwwww gggggg

there are 16 in total so it would be 6/16 because of each color like bb ww gg thats 6 out of 16

The probability of getting 2 socks of the same color is 1/3.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

In the drawer,

Number of blue socks = 2

Number of white socks = 8

Number of gray socks = 6

Total number of socks  = 2 + 8 + 6 = 16

The Total ways to select 2 socks form 16 socks is 120.

The Total ways to select 2 socks of the same color is

T = Possible ways of (2 blue + 2 white +2 gray) socks = 40

The probability of getting 2 socks of the same color is

= 40/120

= 1/3

Therefore, the probability of getting 2 socks of the same color is 1/3.

Triangle FGH is rotated and then dilated by a scale factor of n to form triangle F’G’H’.

If FGH F’G’H’ what is the value of n

Answers

Answer:

B. [tex] n = \frac{1}{3} [/tex]

Step-by-step explanation:

If ∆FGH ~ ∆F'G'H', then their corresponding side lengths would be proportional. This means:

F'G'/FG = G'H'/GH = F'H'/FH = n

The ratio of any of their corresponding side lengths will give you the value of n.

Therefore:

n = F'G'/FG

F'G' = 5

FG = 15

Thus,

[tex] n = \frac{5}{15} [/tex]

[tex] n = \frac{1}{3} [/tex]

The scale factor which is a fraction implies that the size of ∆FGH was reduced after dilation.
