Answer:

If I'm not wrong, I think it's 0.5

Step-by-step explanation:

This is because if the false posative rate 23% and there are 2 people, you would find 23% of 2, which gives you 0.46.  Rounded, this is 0.5. So there is  a 0.5% probability that more than 0 valenteers will get false posative results.

2^5, 6^3, 3^4, 5^3

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

Area = base x height

So you would start by multiplying you 2 side lengths given:

Area = 2 sqrt 3 x sqrt 27

2 sqrt 3 x sqrt 27 = 18

Once multiplied, you will get you area. Which is 18 units squared.

Answer:

151.5 cm^2

Step-by-step explanation:

lets cut stright acrros so you have a triangle 13 (base) by 3 cm (high)

area of a triangle is 1/2 base times hight --> 13x3/2 = 19.5cm^2

now lets doi the rectangle that is 12 by 11

Length times hight is the area is 132

add both areas 132 + 19.5

Answer:

(20 - 3x) + (20 - 7x) = 25 with x being the price of the item bought. (I think)

Step-by-step explanation:

I believe this would be the equation, I'm not sure what the answer would be though, sorry about that.

Answer:

X= $1.5

Step-by-step explanation:

y=mx +b

Y= total amount they had,  M= the amount they bought,  X= how much the item cost, B= the amount they of change they had left

40= 10x + 25

Subtract 25 from both sides

40-25= 15

15= 10x

divide 10 from both sides

15/10= 1.5

x= 1.5

Answer:

x = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Given

2x = 7 ( divide both sides by 2 )

x = [tex]\frac{7}{2}[/tex]

Answer:

x=-3

Step-by-step explanation:

Answer: All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Answer:

$16

Step-by-step explanation:

60 + 4 = 64

64 ÷ 4 = 16

CHECK:

16 x 4 = 64

64 - 4 = 60

Answer:

2/3 = 8/12

3/4 = 9/12

Step-by-step explanation:

whatever you do to the denominator, you have to do the the numerator.

2/3 - 3 times 4 equals 12 and 2 times 4 = 8. so 2/3 = 8/12

3/4 - 4 times 3 equals 12 and 3 times 3 equals 9. so 3/4 = 9/12

Answer:

8.75h = 50

Step-by-step explanation:

h is the number of hours Thomas needs to groom the dogs.

The rate is $8.75 per hour.

His goal is $50.

$8.75 × h = $50

$8.75h = $50

Step-by-step explanation:

Per h =8.75

Then 50=?h

H=50/8.75= 5.71.... Ans

Answer:

The smallest combination of the numbers is 20 and 140

Step-by-step explanation:

The given parameters are;

The Highest Common Factor HCF of the two number = 20

The Lowest Common Multiple LCM of both numbers = Multiple of 14

Let x and y represent the two numbers, we are given;

x > y

We have;

[tex]L.C.M. = \dfrac{Product \ of \ the \ numbers}{H.C.F.}[/tex]

Substituting the known values, we have;

[tex]x \times 14 = \dfrac{Product \ of \ the \ numbers}{20}[/tex]

The product of the numbers = x × 14 × 20

The possible products of the numbers are;

280, 560, 840, 1,120, 1,400, 1,680, 1,960, 2,240, 2.520, 2,800, 3,080, 3,360, 3,640, 3,920

Dividing the possible products by 20 gives, the smallest quotient that is also a multiple of 20 as 140, from which we have;

20 × 140 = 2,800

Therefore, the smallest combination of the numbers = 20 and 140.

Answer:

x=20

Step-by-step explanation:

Look Angle A and D are Congruent so they equal the same

3x−10=2x+10

Subtract 2x from both sides

3x−10−2x=2x+10−2x

x−10=10

Add 10 to both sides.

x−10+10=10+10

x=20

Answer:

A.(1,2)

Step-by-step explanation:

Step: Substitute

−2 /3 y +  7 /3

4x−12y=−20:

4x−12y=−20

4( −2 /3 y +  7 /3 )−12y=−20

-44/3y +  28 /3 =−20(Simplify both sides of the equation)

−44 /3 y +  28 /3  +  −28 /3  =−20+  −28 /3

(Add (-28)/3 to both sides)

−44 /3 y=  −88 /3

−44 /3 y

−44 /3 =  −88 /3  −44 /3

(Divide both sides by (-44)/3)

y=2

Step: Substitute2foryinx=

−2 /3 y+ 7 /3 :

x= −2 /3 y+ 7 /3

x= −2 /3 (2)+ 7 /3

x=1(Simplify both sides of the equation)

Answer:

x=1 and y=2
