Will mark the Brainliest !!!!! A team of 5 boys and 4 girls will be chosen from a group of 16 boys and 13 girls,

vfiekz [6]

Answer:

Step-by-step explanation:

The total number of permutations of boys and girls on the team are:

¹⁶P₅*¹³P₄

Bob will be one of the fixed boys to be picked. Hence, actually 4 boys are to be picked from 15. The permutations of girls being picked remains the same.

Probability = Permutations with Bob as one of the boys / Total permutations

Probability = (¹⁵P₄*¹³P₄) / (¹⁶P₅*¹³P₄) = ¹⁵P₄ / ¹⁶P₅

Probability = $\frac{15!}{(15-4)!}/\frac{16!}{(16-5)!}$ = 15! / 16! = 1/16

Now, Bob is one of the fixed boys and Jane is one of the fixed girls. Hence, actually 4 boys are to be picked from 15 and 3 girls are to be picked from 12.

Probability = Permutations with bob as one of the boys and jane as one of the girls / Total permutations

Probability = (¹⁵P₄*¹²P₃) / (¹⁶P₅*¹³P₄) = (1/16)*(1/13) = 1/208

Now, the probability that at least Jane or Bob will be picked has been asked. This probability is a combination of three probabilities:

Probability = (Probability that only Bob will be picked) + (Probability that only Jane will be picked) + (Probability that both will be picked)

Probability = 1/16 + 1/13 + 1/208 = 0.123

Total teams possible = ¹⁶P₅*¹³P₄ = 8994585600 teams are possible

I need help, help me plz !!!!! Match the verbal expression (term) with its algebraic expression (definition). Match Term Definit

Answer:

Four less than an unknown value E) $y-4$

Quotient of a variable and four B) $\frac{z}{4}$

Some number to the power of four A) $a^4$

Four times an unknown value D) $4x$

Four more than some number C) $b+4$

Step-by-step explanation:

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling $y$ the unknown value, it means we have to write

$y-4$

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling $z$ the unknown variabl, it means we have to write

$\frac{z}{4}$

- Some number to the power of four --> this means that we have to write the power of a number, in the form $a^m$ , where m in this case is equal to 4. Calling $a$ the unknown number, it means we have to write

$a^4$

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling $x$ our unknown values, we have to write

$4x$

- Four more than some number --> this means we have to add 4 to an unknown number. Calling $b$ the unknown number, it means we have to write

$b+4$

. A triangle has side lengths of 8, 7, and 14. To the nearest tenth of a degree find the measure of the angle opposite the side

4vir4ik [10]

Given:

The measure of three sides of a triangle are 8, 7 and 14.

To find:

The measure of the angle opposite the side of length 8.

Solution:

According to the Law of Cosine:

$\cos A=\dfrac{b^2+c^2-a^2}{2bc}$

Let a=8, b=7 and c=14, then by using Law of Cosine, we get

$\cos A=\dfrac{7^2+14^2-8^2}{2(7)(14)}$

$\cos A=\dfrac{49+196-64}{196}$

$\cos A=\dfrac{181}{196}$

Taking cos inverse on both sides.

$A=\cos^{-1}\dfrac{181}{196}$

$A=22.561328$

$A\approx 22.6$

Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.

Petra jogs 5 miles in 40 minutes. At this rate, how long would it take her to jog 7 miles?

Wittaler [7]

(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min

At the same rate, it would take Petra 56 minutes to jog 7 miles.
