Answer:

x=2/5 y−2

Step-by-step explanation:

Answer:

x-intercepts = (-2,0)

y-intercepts = (0,5)

Step-by-step explanation:

First, make the equation into slope-intercept form. (y=mx+b)

y=5/2x+5

b= the y-intercept so y-intercept = 5.

If you graph this line, you can see that the x-intercept = -2.

Answer:

the probability that at least one envelope is a yellow envelope is 16/21

Step-by-step explanation:

The probability that at least one envelope is a yellow envelope is P(Y);

P(Y) = 1 - P(Y)'

P(Y)' is the probability that no envelope is a yellow envelope.

Given;

red envelope = 1

blue envelopes = 3

green envelopes = 2

yellow envelopes = 3

Total = 9

Number of non-yellow envelope = 9 -3 = 6

(6 envelope are not yellow)

P(Y)' = P1 × P2 × P3

Since there is no replacement;

P(Y)' = 6/9 × 5/8 × 4/7

P(Y)' = 5/21

From equation 1;

P(Y) = 1 - 5/21

P(Y) = 16/21

the probability that at least one envelope is a yellow envelope is 16/21.

Answer:

no

Step-by-step explanation:

Substitute the point into the equation

y=8

1 =8

This is not true so the point is not a solution

Answer:

No

Step-by-step explanation:

To test whether an ordered pair is a solution of an equation, we simply plug in the x-coordinate in for x and the y-coordinate in for y and then examine the outcome to see if the resulting equation is true.

Here, substitute 8 in for x and 1 in for y:

y = x

1 = 8

Clearly, we see that 1 is NOT equal to 8, which means (8, 1) is not a solution to the equation y = x.

Thus, the answer is no.

Answer:

Jamie must sprint 107 meter to pass Shelly at point A.

Step-by-step explanation:

Circumference of a sector of the circle is represented by,

Circumference = [tex]\frac{\theta}{360}(2\pi r)[/tex]

where θ = central angle subtended at the center by an arc

r = radius of the circle

[tex]m(\widehat{AB})[/tex] = [tex]\frac{123}{360}(2\pi )(50)[/tex]

           = 34.1667π

           = 107.34 meter

           ≈ 107 meter

Therefore, Jamie must sprint 107 meter to pass Shelly at point A.

Hey there! :)

Answer:

x = 3.

Step-by-step explanation:

Given:

[tex](8x-8)^{\frac{3}{2} } = 64[/tex]

Rule of fractions in exponents:

Numerator- power

Denominator- root

Take the 2/3 root of both sides:

[tex](8x-8) = 64x^{\frac{2}{3} }[/tex]

Simplify [tex]64x^{\frac{2}{3} }[/tex]

Cube root of 64 = 4

4² = 16.

Therefore:

8x - 8 = 16

Add 8 to both sides:

8x = 24

Divide both sides by 8:

x = 3.

Answer:

Factors: 5x, 3x²y⁵   Not Factor: 10x⁴y³

Step-by-step explanation:

5x is a factor because 15x²y⁶= 5x•3xy⁶

3x²y⁵ is a factor because 15x²y⁶ = 3x²y⁵•5y

10x⁴y³ isn't a factor because 15:10=1.5 isn't integer

Answer:

sin70° = x/6

Step-by-step explanation:

When we draw out our picture and triangle, we should see that our angle is on the ground 70°, the height x is across from the angle and is the vertical leg up, and that our hypotenuse is equal to 6:

sin70° = x/6

Answer:

B) 135 degrees

A) 83 degrees

Step-by-step explanation:

Each interior angle of a regular octagon is 135 degrees large.

In question two, <1 is an inscribed angle.  A circle has 360 degrees, so the intercepted arc of <1 is 166, so m<1=83.

Hope it helps <3

If you want a more in-depth explanation, just ask :)

Answer:

B. 135 deg

C. 79 deg

Step-by-step explanation:

We con only find a solution if the octagon is regular. This is not stated in the problem, but we must assume it is to find an answer.

Sum of the measures of the interior angles of a polygon with n sides:

180(n - 2)

For an octagon, n = 8, so we have

180(8 - 2) = 180 * 6 = 1080

For a regular octagon, all interior angles are congruent.

measure of 1 interior angle = 1080/8 = 135

Answer: 135 deg

Arcs measure: 68 deg, 134 deg

Add them: 68 deg + 134 deg = 202 deg

Subtract from 360 deg:

360 deg - 202 deg = 158 deg

The arc intercepted by angle 1 measures 158 deg.

The measure of an inscribed angle is half the measure of its intercepted arc.

m<1 = (1/2) * 158 = 79 deg

Answer:

16589.44

Step-by-step explanation:

z score for 99% confidence interval = 2.576

Margin of error = 1% = 0.01

Formula =

Margin of error = z score × p(1 - p)/n

0.01=2.576 × √ (0.25)/n

0.01=2.576 × 0.5/√ (n)

Crops Multiply

0.01× √ (n) = 2.576 × 0.5

divide both sides by 0.01

√(n) = 2.576 × 0.5/ 0.01

√n =128.8

Square bother sides

n = 128.8²

n = 16589.44

∠VWZ = ∠YWZ        Angles are congruent (def of ∠ bisector)

     WZ = WZ            Sides are the same (reflexive property)

The radius goes from the center to the edge of the circle.

The diameter is twice as long as the radius; it is a segment going through the center with both endpoints on the circle

The circumference is the distance around the circle. Think of it as the perimeter of the circle.

Step-by-step explanation:

The length of PQ is the distance of the walkways  plus the length of garden  plus the walkway

  = (4+x+9+4)

Add the terms together

 = x + 17

Answer:

33.5 ft and 24.5 ft

Step-by-step explanation:

PQ= l

PS= w = l - 9

lw- (l - 8)(w - 8)=400

l(l-9)- (l - 8)(l - 9 - 8)=400

l²-9l - (l - 8)(l - 17)=400

l² - 9l - l² +25l -136=400

16l= 536

l=536/16

l= 33.5 ft

w= 24.5 ft

Answer:

183.26cm

Step-by-step explanation:

Radius of the Circle = 50cm

Let the point be at A

It turns forward 210 degrees to B.

Therefore, the central angle subtended by the arc AB = 210 degrees

The movement of the point from A to B will be the length of the arc AB.

[tex]\text{Length of an arc }=\dfrac{\theta}{360} \times 2\pi r \\$Therefore, the distance moved forward$\\=\dfrac{210}{360} \times 2\times\pi \times 50\\\\=183.26$ cm[/tex]

Answer:

C. (-1.5, 8.875)

Step-by-step explanation:

on a coordinate plane if point(x1,y1) and (x2,y2) is divided by a point p in ratio of m:n then coordinate of point p is given by

p = (nx1 + mx2/ m+n, ny1+my2/m+n)

_______________________________________________

Given point

A (-9, 4) and B (11, 17)

ratio 3:5

m:n = 3:5

m+n = 3+5 = 8

coordinate of point p that partition AB

x = (5*-9 + 3*11) / 5+3                   y =    (5*4 + 3*17) / 5+3

x = (-45 + 33) / 8                          y =    (20 + 51) / 8

x = (-12) / 8                                     y =    (71) / 8

x = -3 / 2 = -1.5                                    y =    8.875

Thus, coordinate of point p is (-1.5, 8.875).
