Answer:

It is not valid because she only saw 5 students and that's not a large enough sample for the whole school.

Step-by-step explanation:

While 4/5 IS 80%, the nurse assumed that 80% of ALL of the students in the school were coming down with colds. This is not true since only 4 students had colds. If she were specific and said that 4/5 students who visited her on Monday were 80% coming down with colds, she'd be right. But she isn't since she's assuming it's 80% of the whole school's population of students.

Step-by-step explanation:

Given that :

The side length = x

To obtain the amount of fabric which would be required for covering the funky, we Obtian the total surface area of the foam. Cube.

Using he relation :

Surface area of a cube = 6 * s² ; the side length s = x

Surface area = 6 * x².

Hypothetically,

Let x = 7 cm

Answer:

$8.50

Step-by-step explanation:

[tex]\frac{y}{22.10} =\frac{1}{2.6}[/tex]

2.6 × y = 22.1 × 1

2.6y = 22.1

2.6y ÷ 2.6 = 22.1 ÷ 2.6

y = 8.5

Answer: 8.50

Step-by-step explanation: 8.50

Step-by-step explanation:

Divide $22.10 over 2.6 pounds of covered cherries

Answer:

m = 7

Step-by-step explanation:

Perpendicular slopes are negative reciprocals so:

m of A = -1/7

m of B = 7

(I think that says 51...)

Basically all you do is multiply 51 by 4

 51

x  4

104

The answer (if those numbers are correct) is 104.

Answer:

The answer is 4.

Step-by-step explanation:

To find the mean absolute deviation of the data you provided, you need to find the mean first. You add all the points together to get 138. Then you divide that number by how many points there are which there are 6 points so you divide 138 by 6 to get 23. Then you calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. Once you add up all the numbers to get 24, you divided them by how many points there are which is 6 again. You should get 4 in the end.

Hope that helps. =)

Answer: A. 5.6267 X 10^8

Step-by-step explanation:

(5.62 X 10^8) + (6.7 X 10^5)= 562670000

Which has 8 numbers after 5

5.6267 X 10^8 has 8 as well just minus the zeroes

Answer:

Number of rats : Food weight = 1 : 5

Step-by-step explanation:

Number of rats in the group = 9

Weight of food carried away by them = 45 kg

Ratio of the number of rats and food weight = [tex]\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}[/tex]

                                                                          = [tex]\frac{9}{45}[/tex]

                                                                          = [tex]\frac{1\times 9}{5\times 9}[/tex]

                                                                          = [tex]\frac{1}{5}[/tex]

Therefore, Number of rats : Food weight = 1 : 5

Substitution

substitute -3-5 into y

it becomes -3-5=6x+4

solve the equation to find the answer for X

then substitute the value of X you found again into the equation to find Y

i'll edit my answer if you give them to me and i know the answer

Step-by-step explanation:

Answer:

It has two numbers per turn. The first is 2 and stays the same the whole time. The second number starts as 5, but every time it hits that number, it increases by 1.

Step-by-step:

As we already know, two starts off the turn, so every number on this turn will increase by 2 (6+2=8.)

Now, for this one, we have five, so for this turn we'll increase it by that much (8+5=13).

However, this number won't stay at 5. Instead, it will increase by 1 every time we hit this turn. Let's continue one:

Turn Two = 13+2=15

Turn 5+1 = 6 = 15+6=21

Turn Two = 21+2=23

Turn 6+1 = 7 = 23+7=31

And from there, the pattern would/will continue!

Answer: 65

Step-by-step explanation:

Measure of ∠M to the nearest degree is [tex]65^{0}[/tex].

The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.

Given

k = 76 inches

l = 30 inches

m = 69 inches

From the law of cosines

Cos <M = [tex]\frac{k^{2} +l^{2} -m^{2} }{2.k.l}[/tex]

Cos <M = [tex]\frac{76^{2} +30^{2} -69^{2} }{2.76.30}[/tex]

Cos <M = [tex]\frac{1915}{4560}[/tex]

Cos <M = 0.42

<M  = [tex]cos^{-1} (0.42)[/tex]

<M ≈ [tex]65^{0}[/tex]

Hence, measure of ∠M to the nearest degree is [tex]65^{0}[/tex].
