Question 4

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

Explanation:

There are 5 green, 9 red, and 6 blue. That makes 5+9+6 = 20 total marbles. Of this total, 6 are blue. The probability of picking blue is 6/20 = 3/10

==============================================================

Question 5

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

Explanation:

The open hole at 6 means we do not include this value as part of the shaded solution set. So we either have "less than" or "greater than".

We go with "less than" since the shaded region is to the left. This describes all values smaller than 6.

If you had "or equal to" as part of the inequality, then you would have a filled in circle at the endpoint.

= 90/2.5

=36km/h

Answer:

160

Step-by-step explanation:

If the scale factor is 4, we would have to multiply the height and width by 4

4*5=20

4*4=16

Now to find the area of the triangle using the formula (20*16)/2

That equals to 160

Answer:

y=50 and z=60 (vertically opposite)

x+60+y=180

or x+60+50=180

or x+110=180

or x=70

Answer:

Step-by-step explanation:

a.x = 95 degree

reason = being vertically opposite angles

x + 145 degree = 180 degree

x = 180 -145

x=35 degree

reason = being linear pair

b.40 + x =90 degree

x = 90 - 40

x = 50 degree

reason = being perpendicular

y = x + 40

y = 50 + 40

y = 90 degree

reason = being vertically opposite angles

c.50 + 60 + x=180 degree

110 + x =180

x = 180-110

x = 70 degree

reason = being linear pair

z = 60 degree

reason = being vertically opposite angles

y = 50 degree

reason = being vertically opposite angles

d. x = 80 +10

x =90 degree

reason = being vertically opposite angles

y + x =180 degree

y + 90 =180

y = 180 - 90

y = 90 degree

reason = being linear pair

Answer:

D - 10^2+24^2

Step-by-step explanation:

So, there are a few important things here to go over:

First off, the formula for area of square is l*w, but since a square's length and width are equal, this will just be l^2.

Secondly, the formula for pythagreons theorm is a^2+b^2=c^2. This is what we will use to find the side length of A.

So, we see that there is a triangle that is made up of the top side of the organge square, the left side of the green square, and the right side of the blue square.

To find the righ side of the blue square, we need to use the pythagreons theorm.

This is because the hypotenuse of the triangle(C), is also the right side of square A.

The A and B that we use to find C in pythagreons theorm we know is 24 and 10.

Lets plug this in:

10^2+24^2=c^2

=

100+576=676

Normallu, to find the length of the side, we would root the 676. However, since area is x^2, and we found ^2=676, we are fine.

So tecnically, 10^2+24^2=A.

Or:

[tex]10^2+24^2=A[/tex]

This looks like D

Answer: The age of Mr. Lang's youngest son is 7 years old.

Step-by-step explanation:

Let's start by listing the factors of 84. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84.

We can only use numbers that are under 19 since we must add up to that total. Now we are left with 1, 2, 3, 4, 6, 7, 12, and 14,

1 can't be an option since 18 is not there to pair with it to add together for 19. For the same reason we can eliminate 2, 3, 4, 6, and 14.

Now we are left with 7 and 12. Let's see is they will work.

7+12=19

7×12=84

[tex]52[/tex] square units

Step-by-step explanation:

The formula for the area of a rectangle is  [tex]A=lw[/tex]  where [tex]l[/tex] stands for the length and [tex]w[/tex] stands for the width.

---------->>>>

First, let's find the area of the outside rectangle.

The width of the outside rectangle is 6 units and the length is 11 units.

So,

[tex]A=6(11)[/tex]

[tex]A=66[/tex] square units

This is the area of the yellow rectangle.

---------->>>>

Now, let's find the area of the red rectangle.

The width of the red rectangle is 2 units and the length is 7 units.

So,

[tex]A=2(7)[/tex]

[tex]A=14[/tex] square units

This is the area of the red rectangle.

---------->>>>

Now, to find the answer, we must subtract the area of the outside rectangle by the area of the red rectangle to find the area shaded in yellow.

Answer:

9

Step-by-step explanation:

A sandwich shop advertises 108 combinations (one meat + one cheese).

There are 3 types of bread and 4 cheeses.

Number of combinations:

3 × 4 = 12 combinations

Therefore, the number of different meats that they do offer is calculated as:

= 108 combinations/ Number of combinations for meat and cheese

108 combinations/12 combinations

= 9 different meats

Answer:

Y=75x+125

Step-by-step explanation:

Your answer is correct. It is c. The equation is y=Mx+b where m is the slope and b is the y intercrept.

To get M (the slope), get the difference of y-y/x-x. You can use any value of y and x. So, 575-500/6-5=75/1 ot 75. Therefore 75 is m in the equation y=Mx+b.

To get b, you figure out what y is when x is 0. So, looking at the numbers, subtract 75 from 350, which means that  y is 275 when x is 2. Subtract 75 again to get 200 (275-75) when x is 1. Subtract 75 one more time to get y when x is 0. 200-75=125. 125 is the y intercept.

Going back to the equation y-Mx+b. Fill in m and b. Y=75x+125.

Answer:

7x + 2y = 1

Step-by-step explanation:

First we find the slope m of the line

The slope of a line that passes through 2 points x1, y1 and x2 , y2 is given as

m = (y2 - y1)/(x2 - x1)

Considering the points (–3, 11) and K(1, –3), the slope of the line m

= (-3-11)/(1 --3)

= -14/4

= 7/2

the line JK may be given as

y - 11 = -7/2(x - -3)

multiply through the equation by 2

2y - 22 = -7(x + 3)

2y - 22 = -7x - 21

7x + 2y = 22 - 21

7x + 2y = 1

Answer:

B

Step-by-step explanation:

7x + 2y = 1

Answer:

Step-by-step explanation:

The degrees around a point = 360, so

1. x + 95 + 3y + 80 = 360 so

2. x + 3y = 185

3. 65 + 3y = 185 and

3y = 120 so

y = 40

Answer:

y=40

Step-by-step explanation:

sum of all 3 angles : 240

3y+240=360

3y=360-240=120

y=3÷120

y=40

Answer:

[tex]\text{B. }\triangle DKM[/tex]

Step-by-step explanation:

When naming a triangle or any polygon, the name should consists of either the center of the polygon or each of the vertices (points) of the triangle. In this case, no center is labelled, so we will use the vertices to name the triangle.

The vertices or points of the triangle are D, K, and M. Therefore, we name this triangle by writing a triangle symbol [tex]\triangle[/tex] followed by these vertices.

Unless you're comparing it to another polygon (e.g. writing a similarity statement), the order of which you list the vertices does not matter, but you should start with a point and move either clockwise or counterclockwise until you list every point. Therefore, the answer is [tex]\boxed{\text{B. }\triangle DKM}[/tex].

Solution:

Required margin of error  = 0.05

Estimated population proportion p = 0.8

Significance level = 0.10

The [tex]\text{provided estimate population proportion}[/tex] p is 0.8

The significance level, α = 0.1 is [tex]z_c=1.645[/tex], which is obtained by looking into a standard normal probability table.

The number of patients surveyed to estimate the population proportion p within the required margin of error :

[tex]$n \geq p(1-p)\left(\frac{z_c}{E}\right)^2$[/tex]

  [tex]$=0.8\times (1-0.8)\left(\frac{1.64}{0.05}\right)^2$[/tex]

  = 173.15

Therefore, the number of patients surveyed to satisfy the condition is n ≥ 173.15 and  it must be an integer number.

Thus we conclude that the number of patients surveyed so the margin of error of 90% confidence interval is within 0.05 are n= 174.

We are given the equation below:

[tex] \large{ {p}^{2} = \frac{9}{36} }[/tex]

Use the property below:

[tex] \large \boxed{ {x}^{2} = \frac{a}{b} \longrightarrow x = \pm \frac{ \sqrt{a} }{ \sqrt{b} } \: \: (a \geqslant 0 \: \: and \: \: b > 0)}[/tex]

From the equation:

[tex] \large{p = \pm \frac{ \sqrt{9} }{ \sqrt{36} } } \\ \large{p = \pm \frac{3}{6} \longrightarrow p = \pm \frac{1}{2} }[/tex]

Hence the answer is p = ± 1/2.

Both answers work. The second answer is in the plus-minus form.
