Mr. Ramsey has 14 girls and 10 boys in her class she will randomly create one group of three students to work on a project what

Mrrafil [7]

The probability that the group will be all girls is 91/506

<h3 /><h3>Number of ways of selecting 3 students out of the total</h3>

Since there are 14 girls and 10 boys, the total number of students is 10 + 14 = 24.

So, the total number of ways of selecting 3 students from 24 is ²⁴C₃.

<h3 /><h3>Number of ways of selecting 3 girls out of 14</h3>

Also, the total number of ways of selecting a group of 3 of all girls out of the 14 girls is ¹⁴C₃ = 14

<h3 /><h3>Probability of all girls</h3>

So, the probability of selecting a group of 3 of all girls = number of ways of selecting 3 girls/total number of selections = ¹⁴C₃ ÷ ²⁴C₃

= 14 × 13 × 12/3! ÷ 24 × 23 × 22/3!

= 7 × 13/23 × 22

= 91/506

So, the probability that the group will be all girls is 91/506

Examine the two functions below. Use the equation and table given to answer the question below.

Natalka [10]

<span>A.
Both functions have the same y-intercept.</span> TRUE

<span>B.
f(x) has a negative slope while g(x) has a positive slope.</span> Tricky question. Yes, f(x) has the negative slope m = -2. However, g(x), being a curve, does not have a single slope; rather, it has a varying slope that increases (becomes less negative) as x increases. Some people might argue that this statement is TRUE, while others would argue that it's FALSE, because the 2nd function does not have just one single value for the slope.

<span>C.
Both functions are linear functions.</span> ABSOLUTELY NOT. The first one is linear; the second is a "decaying exponential" whose graph is a curve.

D. <span>
g(x) has a common ratio of 4. Yes and no. I'd say the common ratio is (1/4), because each y value is (1/4) of the previous y value

The midpoint of AB is M(7,-2). If the coordinates of A are (8,3), what are the<br> coordinates of B?

strojnjashka [21]

Answer:

Step-by-step explanation:

We can find it like:

$x_{B}= 2x_{M}- x_{A} = 2*7 - 8 = 14 - 8= 6\\ \\y_{B}= 2y_{M}- y_{A} = 2*(-2) - 3 = - 4 - 3= - 7$
