What is the value of y in the triangle?

Answer:

The mean squares has d.f (n-1)

Step-by-step explanation:

The total number of degrees of freedom is n-1 as there is only one restriction of computing the grand mean. The d.f for k samples is k-1 beacuase the mean of the sample means must equal the grand mean. Similarly , the d.f for within SS is n-k , due to the k restrictions of computing the k sample means. Hence we find that

Total df= Within df + Between df

n-1=  (n-k)+(k-1)

Between SS has (k-1) d.f

Within SS has (n-k) d.f

These two quantities are known as mean squares and has d.f (n-1)

Answer:

5 m

Step-by-step explanation:

Set up an equation using the square area formula, A = s²

Let x represent the original side length:

(x + 3)² = 64

Simplify:

x² + 6x + 9 = 64

Subtract 64 from both sides:

x² + 6x - 55

Factor by finding 2 factors of -55 that add up to 6:

(x + 11)(x - 5) = 0

Solve for the 2 solutions:

x + 11 = 0

x = -11

x - 5 = 0

x = 5

The side length cannot be be negative, so the answer is 5.

The side length of the original square is 5 m.

Let

x--------> the border’s length

y--------> the border’s width

P--------> perimeter of the border

we know that

x=5+y------> equation 1

P=2*[x+y]-----> P=2x+2y

P <=180 ft

(2x+2y) <= 180-------> equation 2

substitute the equation 1 in equation 2

2*[5+y]+2y <= 180

10+2y+2y <= 180

4y <= 180-10

4y <=170

y <=42.5 ft

so

the maximum value of the width is 42.5 ft

for y=42.5 ft

x=42.5+5------> x=47.5 ft

the answer is

the width of the border is less than or equal to 42.5 ft

Answer:

Step-by-step explanation:

we have a 51 in sandwich

let a piece be x

we have x= shorter piece

another piece is x+6

another piece (x+6)-9=x-3

x+x+6+x-3=51

3x=51-3

3x=48

x=48/3=16

x=16, longer piece is 16+6=22, shorter piece =10

Answer:

Step-by-step explanation:

Calculation for the probability that washing dishes tonight will take me between 10 and 13 minutes

Probability of washing dishes=(13minutes-10minutes)/(15minutes-7minutes)

Probability of washing dishes=3 minutes/8 minutes

Probability of washing dishes=0.375*100

Probability of washing dishes=37.5%

Therefore the probability that washing dishes tonight will take me between 10 and 13 minutes is 37.5%

Answer: the smallest number of people required for the sample to meet the conditions for performing inference is 100

Step-by-step explanation:

Given that;

36% of US population has never been married

32% are divorced

27% are married

5% are widowed

Taking a simple random sample of individuals to test this claim;

we need expected count in each cell to be at least 5, here the smallest proportion is 5% = 0.05

so we only need to satisfy condition for its expected count;

n × 0.05 ≥ 5

n = 5 / 0.05 = 100

Therefore the smallest number of people required for the sample to meet the conditions for performing inference is 100

Answer:

[tex]m = \frac{10}{6}[/tex]

Step-by-step explanation:

Slope can be found by using the following equation. Note that [tex]m[/tex] is slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (-3 , -5)\\(x_2 , y_2) = (3 , 5)[/tex]

Plug in the corresponding numbers to the corresponding variables:

[tex]m = \frac{5 - (-5)}{3 - (-3)}[/tex]

Note that when two negative signs are directly next to each other, they become a positive. Add across:

[tex]m = \frac{5 + 5}{3 + 3} = \frac{10}{6}[/tex]

[tex]m = \frac{10}{6}[/tex]

Answer:

14 inches of the original length of ribbon is left.

Step-by-step explanation:

It is given that the total length of ribbon is 32 inches.

It is also given that he cuts six 3-inch pieces from the original length. This means:

6*3 = 18 inches

18 inches are cut from the total length of ribbon.

So the remaining ribbon will be:

= 32-18 = 14 inches

Hence,

14 inches of the original length of ribbon is left.

The quantity of almond milk he added was = -3/8cups

The recipe for the smoothie = berries 3/8, mango 1/2, yogurt 3/4 cups and almond milk (x) cups

The total quantity of smoothie = 2 cup (two 8-fluid ounce servings in all).

That is; 3/8 + 1/2 + 3/4 + x = 2

Making x the subject of formula;

[tex]x = (\frac{3}{8} + \frac{1}{2} + \frac{3}{4} ) - 2[/tex]

LCM of 8, 2 and 4 = 8

[tex]x = \frac{3 + 4 + 6}{8} [/tex]

[tex]x = \frac{13}{8} [/tex]

Therefore, x = 13/8 -2

LCM = 8

X= 13- 16/8

Answer:

  [tex]\text{A)}\quad\dfrac{9}{x+y}[/tex]

Step-by-step explanation:

In the English expression, you need to understand that "A divided by B" means that A is the numerator and B is the denominator of the fraction representing the division. Here, "B" is "the quantity of ...", which means that the stuff after "of ..." is to be treated as a single item, the denominator in this case. That item is "x plus y." So, the expression in math terms is ...

  [tex]\dfrac{9}{x+y}[/tex]

When this is written in plain text, the "quantity" is put in parentheses, because the fraction bar no longer serves as a grouping symbol:

  9/(x+y)

These expressions match the first choice, A.

Answer:

The order of the sides of each triangle from shortest to longest.

Step-by-step explanation:

Given the triangle CDE

We know that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

as

angle D=35° < angle C=60° < angle E=85°

It means:

Therefore,

angle D=35° < angle C=60° < angle E=85°

CE                 <       DE           <           CD

Hence, the order of the sides of each triangle from shortest to longest.

Answer:

The projected annual sales of Satelite Corporation are $ 161,805.

Step-by-step explanation:

Given that Satellite Corporation projects a year-end net income of $ 64,722, and that the net income represents 40% of its projected annual sales, to determine the amount of the projected annual sales of the company the following calculation must be performed:

40 = 64.722

100 = X

(100 x 64,722) / 40 = X

6,472,200 / 40 = X

161.805 = X

Therefore, the projected annual sales of Satelite Corporation are $ 161,805.

Answer:

Step-by-step explanation:

Given that:

[tex]d = 2t^2[/tex] and [tex]d = 10t - 8[/tex]

If we equate both since they are distances, we have:

[tex]2t^2 = 10t - 8[/tex]  

Algebraically, moving the equation to the right side, we get:

[tex]2t^ 2 = 10t -8 \\ \\ 2t^2 -10t +8 =0[/tex]

To factor the equation on the left side:

[tex]2t^2 - 10t + 8 = 0[/tex]

Factor out 2 on the left-hand side:

[tex]2 (t^2 -5t + 4) =0[/tex]

[tex]=2 (t^2 -t-4t + 4)[/tex]

[tex]= 2[t(t-1)-4(t-1)][/tex]

[tex]=2(t-1) (t-4)[/tex]

To determine the time when the two boats have to cover an equal distance:

[tex]2(t -1)(t-4) =0 \\ \\(t-1)(t-4) =0[/tex]

Thus:

[tex]t - 1 = 0 \ or \ t - 4 = 0 \\ \\ t = 1 \ or \ t = 4[/tex]
