Answer:

p(not 5) = 5/6

Step-by-step explanation:

The probability that we roll a 5 is 1/6. So, the probability we don't roll a five is simple 1 minus that:

$1-\frac{1}{6} = \frac{5}{6}$

And that's your answer.

Find the measure of UT answer choice - 65 51 70 55

muminat

Answer:

Option (4)

Step-by-step explanation:

If two chords intersect outside the circle, angle formed between the chords will be half of the sum of measures of intercepted arcs.

From the given picture,

$m(\angle RQS)=\frac{1}{2}(m\hat{RS}+m\hat{UT})$

95° = $\frac{1}{2}(135+m\hat{UT})$

190 = 135 + $m(\hat{UT})$

$m(\hat{UT})=190-135$

$m(\hat{UT})$ = 55°

Therefore, option (4) will be the correct option.

|x|≥0 for every real value of x

so

|x|/-6=12
divide both sideds by -6

Enny White is shopping for CDs. She decides to purchase 3 movie soundtracks. The music store has 7 different movie soundtracks i

Gala2k [10]

Answer:

35 different selections of soundtracks are possible

Step-by-step explanation:

Total number of soundtracks available at the store = 7

Enny decides to purchase 3 movie soundtracks.

So, in this problem we have to find in how many ways can Enny chose 3 soundtracks out of 7. The order in which the soundtracks are chosen does not matter e.g soundtracks A,B and C are the same as soundtracks B,C and A.

In an arrangement when the order does not matter, we use combinations to find the total possible number of arrangements or selections.

So, for this problem choosing 3 soundtracks out of 7 means forming combinations from 7 objects taken 3 at a time. This can be represented mathematically as:

$^{7}C_{3}$

The general formula for combinations is:

$^{n}C_{r}=\frac{n!}{r!\times(n-r)!}$

Using the values, we get:

$^{7}C_{3}=\frac{7!}{3!\times(7-3)!} =35$

This means, Enny can make 35 different selections of soundtracks.

Gabby has 5 weeks to read a novel. She reads 15 pages of a novel in 3/7 week. At this rate, will gabby read the 200-page book in

docker41 [41]

15 pages - 3/7 of a week
200 pages - x weeks

Cross multiply:
$15x=200 \times \frac{3}{7} \\
15x=\frac{600}{7} \\
x=\frac{600}{7} \times \frac{1}{15} \\ x=\frac{40}{7}\\
x=5.71...>5$

She won't read the book in time.
