Yes, you can. First, you need to find how many times does 6 fits on 31. The nearest whole number in the multiplication table of 6 to 31, is 30 (6x5). So, you subtract that from 31.

31-30= 1

You have a remainder of 1/6.

Now, write the times 6 fits into 31 being a whole number plus the remainder.

5 1/6

Suppose a jar contains 18 red marbles and 38 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same
netineya [11]

Answer: 0.0993

Step-by-step explanation:

Since the jar contains 18 red marbles and 38 blue marbles, the total marbles will be:

= 18 marbles + 38 marbles

= 56 marbles

When 2 marbles are pull out at random at the same time, the probability that both are red will be:

= (18/56) × (17/55)

= 0.3214 × 0.3091

= 0.0993

The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard devi
son4ous [18]

Answer:

Step-by-step explanation:

Since the length of time taken on the SAT for a group of students is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - u)/s

Where

x = length of time

u = mean time

s = standard deviation

From the information given,

u = 2.5 hours

s = 0.25 hours

We want to find the probability that the sample mean is between two hours and three hours.. It is expressed as

P(2 lesser than or equal to x lesser than or equal to 3)

For x = 2,

z = (2 - 2.5)/0.25 = - 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.02275

For x = 3,

z = (3 - 2.5)/0.25 = 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.97725

P(2 lesser than or equal to x lesser than or equal to 3)

= 0.97725 - 0.02275 = 0.9545

One factor of x^3+x^2-14x-24 is x-4. Finding the remaining factors and it’s not -3
iren2701 [21]

Step-by-step explanation:

x³ + x² − 14x − 24

x³ + x² − 20x + 6x − 24

x (x² + x − 20) + 6 (x − 4)

x (x + 5) (x − 4) + 6 (x − 4)

(x (x + 5) + 6) (x − 4)

(x² + 5x + 6) (x − 4)

(x + 2) (x + 3) (x − 4)

The other two factors are x + 2 and x + 3.
