You decided to throw a fair die four times.
Finger [1]

Answer:

If all you care about is whether you roll 2 or not, you get a Binomial distribution with an individual success probability 1/6. The probability of rolling 2 at least two times, is the same as the probability of not rolling 2 at zero or one time.

the answer is, 1 - bin(k=0, n=4, r=1/6) - bin(k=1, n=4, r=1/6). This evaluates to about 13%, just like your result (you just computed all three outcomes satisfying the proposition rather than the two that didn’t).

Answer:

BH = 16

Step-by-step explanation:

The centroid theorem states that the centroid of a triangle is 2/3 of the distance from a vertex to the midpoint of the opposite side.

That means that BH is 2/3 of the length BF.

BH = (2/3)(BF)

BH = (2/3)(24)

BH = 16

Dori and Malory are tracking their steps taken as a health goal. Dori leaves her house at 12:00 p.m. and walks at 50 steps per m
docker41 [41]

Hi There!


Dori leaves her house at 12pm.

50 steps per minute until 12:20pm.

Dori has a 20 minute advantage over Malory, find the amount of steps she is ahead by,

12 - 12:20pm. steps = 20 minutes = 20 x 50 = 1000 steps


Malory leaves her house at 12:20pm.

Walks 90 steps per minute.

12:20 -  12:30 pm. = 10 minutes = 10 x 90 = 900


Dori 12:20 - 12:30pm. = 10 minutes = 10 x 50 = 500

500 + 1000 = 1500


Mallory 12:30 - 12:40 = 10 minutes = 10 x 90 = 900

900 + 900 = 1800


Dori 12:30 - 12:45pm. = 15 minutes = 15 x 50 = 500

1750 + 500 = 2250


Mallory 12:40 - 12:45pm. = 5 minutes = 10 x 90 = 900

450 + 1800 = 2250


Answer: they have the same number steps at 12:45 p.m.

Translate the product of 8 and the quotient of 6 and x into an algebraic expression​
WINSTONCH [101]

Answer:

3 x

x + y

Step-by-step explanation:

(think about it with a horizontal line between the two numbers)

When using fractions and whole numbers turn the whole numbers into fractions like ---> 3/1

and if their like 3 5/6 (for example) you would multiply the denominator by the whole number ---> 3*6=18 then add what's on the numerator with it. so 18+5=23 which would make it 23/6

Just some tips for making it easier!

Hope it helps! :)
