OK so first you’re going to put it all in order from least to greatest so it’s going to be 6, 8, 9, 11, 16, 17, 17. And then you’re going to have to cross out six then the last 17 then 8 then the next 17 then 9 then 16 and then the answer you’ll have it it’s going to be 11

How many times does the line y=-6 intersect with the circle x^2+y^2=36?

Answers

Answer:

a) The line intersects with the circle once.

b) Tangent

Step-by-step explanation:

We are given the following equation for the circle:

[tex]x^2 + y^2 = 36[/tex]

How many times does the line y=-6 intersect with the circle?

We have to find the values of x when [tex]y = -6[/tex]

So

[tex]x^2 + y^2 = 36[/tex]

[tex]x^2 + (-6)^2 = 36[/tex]

[tex]x^2 + 36 = 36[/tex]

[tex]x^2 = 0[/tex]

[tex]x = 0[/tex]

Since the line intersects the circle at one point, it is tangent to the circle.

The line intersects with the circle once.

(a) Angela and Barbra decided to start a business together. Angela invested $24000 and Barbara invested
$16000. They share all profits in the same ratio as the money was invested. they made a
total profit of $15000 at the end of the year, how much money did each person recieve?
(b) sum of money is shared among two friends in the ratio 4:9. If the smaller amount is $560, find the
larger amount.

(c) The sum $4500 is divided among Anesha, Sian and Joanne. Sian received half, Anesha received $1050
and Joanne recieved the remainder. Calculate:
i. Sian's share
ii. Joanne's share
iii. The ratio in which the $4500 was divided among the three persons in simplest form.​

Answers

Answer:

  (a) A : B = $9000 : $6000

  (b) $1260

  (c) A : S : J = $1050 : $2250 : $1200 = 7 : 15 : 8

Step-by-step explanation:

(a) The investment ratio is ...

  Angela : Barbara = 24000 : 16000 = 3 : 2

The profit of 15,000 goes 3/(3+2) = 3/5 to Angela, and 2/5 to Barbara:

  Angela's share: (3/5)($15,000) = $9,000

  Barbara's share: (2/5)($15,000) = $6,000

__

(b) We can multiply the ratio by $140 to see the larger amount:

  4 : 9 = ($140)(4) : ($140)(9) = $560 : $1260

The larger share is $1260.

__

(c) Sian gets (1/2)($4500) = $2250. Anesha gets $1050. So  Joanne gets ...

  $2250 -1050 = $1200

Then the shares are ...

  i. Sian: $2250

  ii. Joanne: $1200

  iii. Ratios: A : S : J = 105 : 225 : 120 = 7 : 15 : 8

What is the measure of angle x?

X= [ ]

Enter your anwer in the blox

Answers

Answer:

160 I think it is im not sure

Since the angle to the right of the angle are vertical angles with 41 it is safe to assume that the one next to it is also 41. So you add 56+41 and then set it equal to 180. 56+41+X =180 So you get 97+X=180 and then you subtract 180-97=X so X =83. And you can double check this by plugging it in to the equation.

97+X(83)=180

In a law office, the average number of billed hours per day was 150 last year. In the first 85 days of this year, the average number of billed hours per day is 158 with a standard deviation of 65 hours. When testing the hypothesis (at the 10% level of signficance) that the average number of billed hours per day has increased, what is the null and alternative hypotheses (please write out the null and alternative hypotheses below AND on your scratch work...failure to do BOTH will result in 0 points)

Answers

Answer:

There isn't enough evidence to reject H0

Step-by-step explanation:

Null hypothesis :

H0: μ = 150

H1 : μ > 150

Decision region :

Reject Null if ;

Pvalue < α

Zstatistic = (x - μ) / (s/sqrt(n))

Zstatistic = (158 - 150) / (65/sqrt(85))

Zstatistic = 0.1135

Using the P value calculator from Zstatistic at 90% ; α = 0.10 confidence interval ; one tailed test = 0.128

Pvalue = 0.128

Since ; 0.128 > 0.10

Pvalue > α

We cannot reject H0:

Answer:

[tex]C = (\frac{33}{5},\frac{19}{5})[/tex]

Step-by-step explanation:

Given

[tex]A = (1,3)[/tex]

[tex]B = (8,4)[/tex]

[tex]AC : BC = 4 : 1[/tex]

Required

Determine the coordinates of C

To do this, we make use of:

[tex]C = (\frac{nx_1 + mx_2}{n+m},\frac{ny_1 + my_2}{n+m})[/tex]

Where:

[tex]A = (1,3)[/tex] ---- [tex](x_1,y_1)[/tex]

[tex]B = (8,4)[/tex] ---- [tex](x_2,y_2)[/tex]

[tex]m:n = 4 : 1[/tex]

So:

[tex]C = (\frac{1 * 1 + 4*8}{1+4},\frac{1*3 + 4*4}{1+4})[/tex]

[tex]C = (\frac{33}{5},\frac{19}{5})[/tex]
