A school event requires at least 3 parents for every 10 kids. How many parents for 50 kids?

Answer:

Hattie travelled 73.25 miles on Saturday and Sunday

hi!

so the original equation is (x^2 -121) / x+ 11.

Those two equations look similar...

well, we know that the top equation looks like a^2 - b^2, and that equation iis equivalent to this equation: (a+b)(a-b).

So if we factor that out, we get:

( (x + 11) * (x-11) )/ (x + 11)

we can cancel the x+11 on the top and the x+11 on the bottom out.

that leaves us with x-11.

Hope this helped!

Answer:

7r-8

Step-by-step explanation:

yout are the two common factors in this case they are 8r and -r which is also -1r and put them in an equation and you di the same for +6 and -14

Firstly we will solve -1r +8r

+8r overpowers -1r so we will use the positive sign for this one. 8-1 is 7 and I we use the positive sign from the overpowered number you get 7r

Now we move on to +6-14

this is just simple addition and subtraction

what is 14-6 it is -8

-14 overpower 6 so we use its sign

Lastly we put it all together and get

7r - 6

Answer:

The number of ways to form different groups of four subjects is 4845.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]

In this case, 4 subjects are randomly selected from a group of 20 subjects.

Compute the number of ways to form different groups of four subjects as follows:

[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]

[tex]{20\choose 4}=\frac{20!}{4!\times (20-4)!}[/tex]

      [tex]=\frac{20\times 19\times 18\times 17\times 16!}{4!\times 16!}\\\\=\frac{20\times 19\times 18\times 17}{4\times3\times 2\times 1}\\\\=4845[/tex]

Thus, the number of ways to form different groups of four subjects is 4845.

Answer:

Two weighing

Step-by-step explanation:

In the context, it is given that one of the three coins is fake and the other two are real. It is also mentioned that the fake coin is either heavier or lighter than the other two real coins.

Now to find the fake coin, we take a balance scale and lace one coin on one pan of the balance and place the second coin on the other pan of the same balance. We keep the third coin aside.

Now we check the balance scale. If the scale is balance, then we can conclude that the coin that we kept aside is the fake coin as both the real coins have same weight.

Now we replace the one of the coin on the pan with the coin that is kept aside and check the balance. Remember now on the pan, there is one real coin and one fake coin. The balance scale will be dis-balance as the fake coin is either heavy or light than the real coin. Thus we can identify the fake coin.

Answer:

b = 9

Step-by-step explanation:

Hello, once again.

Perpendicular lines have negative reciprocal slopes.

The slope would be -2.

Plug the y and x values in.

y = -2x + b

5 = -2(-2) + b

5 = -4 + b

b = 9

Answer:

The answer may be 68?

Step-by-step explanation:

Answer:

44°

Step-by-step explanation:

First, m ∠ D=112° and  ∠ABC are congruent in a parallelogram and congruent angles have same measure so m ∠ ABC=112° as well

Second, ∠ABC and ∠CBE are supplementary angels so they add up to 180° because adjacent angles that form a line are suplementary, therefore, ∠CBE=180-112=68°

Third, ∠CBE≅∠BCE because the ΔCEB is isosceles since is given CE≅BE and base angles of isosceles triangles are congruent.

Congruent ∠s have same measure so m∠BCE =68° as well

Last sum of angles in a Δ is 180° so from  ΔCEB we have

m ∠E = 180-68-68=44°

Hey.. Use a calc dude

This question is incomplete, the complete question is;

X and Y are independent Gaussian (Normal) random Variables. X has mean 13.9 and variance 5.2; Y has mean 6.9 and variance 3.8. . (a) Calculate P( W> 10)

Answer:

P( W> 10) is 0.1587

Step-by-step explanation:

Given that;

X ⇒ N( 13.9, 5.2 )

Y ⇒ N( 6.9, 3.8 )

W = X - Y

Therefore

E(W) = E(X) - E(Y)

= 13.9 - 6.9 = 7

Var(W) = Var(X) + Var(Y) -2COV(X.Y)

[ COV(X,Y) = 0 because they are independent]

Var(W) = 5.2 + 3.8 + 0

= 9

Therefore

W ⇒ N( 7, 9 )

so

P( W > 10 )

= 1 - P( W ≤ 10 )

= 1 - P( W-7 /3   ≤   10-7 /3 )

= 1 - P( Z ≤ 1 )           [ Z = W-7 / 3 ⇒ N(0, 1)  ]

from Standard normal distribution table, P( Z ≤ 1 )  = 0.8413

so

1 - P( Z ≤ 1 )  = 1 - 0.8413 = 0.1587

Therefore P( W> 10) is 0.1587

Answer: y=28 degrees

Step-by-step explanation:

In this problem we used supplementary angles and algebra. We also used congruency.

Answer:

y=-2/3x+500

Step-by-step explanation:

Slope-intercept form: y=mx+b So, you need to get y by itself.

2x+3y=1500  Subtract 2x on both sides.

-2x      -2x

3y=-2x+1500 Divide both sides by 3.

/3   /3

y=-2/3x+500

(The slope is -2/3 and the y-intercept is 500.)

Hope this helps!! Have a wonderful day ^^

Answer:

This is the concept of scale factors; The length of the larger figure will be calculated as follows;

linear scale factor=[length of larger figure]/[length of smaller figure]

plugging the values in the above formula we get:

let the length of the larger figure be x;

thus;

x/12=4/3

multiplying both sides by 12 to solve for x we get:

12*x/12=4/3x12

x=16

thus the length of the larger figure is x=16

Answer:16

Step-by-step explanation:

12 times 4/3 is 4^2 or 16

Answer:

56 ---> m< DAB

4 ---> length of line BC

44 ---> value of y

2 ---> value of x

Step-by-step explanation: edmentum test answer

The length of BC is 4 units, the value of y is 44, a measure of the angle DAB is 56 degrees, and the value of x is 2.

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Parallelogram ABCD

From the figure:

6 - x = x + 2

2x = 4

x = 2

Length of BC = 6 - x = 6 - 2 = 4 units

12 + y = 100 - y

y = 44

Angle DAB = 100 - 44 = 56 degrees

The value of x = 2

Thus, the length of BC is 4 units, the value of y is 44, a measure of the angle DAB is 56 degrees, and the value of x is 2.
