Answer:

The correct statement is (D).

Step-by-step explanation:

Compute the probabilities for the data provided:

Probability students preferring sharks:

$P(\text{Students preferring sharks})=\frac{90}{95}=0.947$

Probability teachers preferring sharks:

$P(\text{Teachers preferring sharks})=\frac{5}{95}=0.053$

Probability students preferring moose:

$P(\text{Students preferring moose})=\frac{10}{20}=0.50$

Probability teachers preferring moose:

$P(\text{Teachers preferring moose})=\frac{10}{20}=0.50$

From the above computations it can be concluded that:

Shark is more popular with students.
Moose is equally popular with students and teachers.

Thus, the correct statement is (D).

Please help me Simplify: 6! − 3!

djverab [1.8K]

Answer: Option B 3!((6×5×4)-1)

Step-by-step explanation:

6! - 3!

= (1×2×3×4×5×6) - (1×2×3)

= 720 - 6

= 714

As you told you forgot to put options lemme answer it.

It will be option B

3!((6×5×4)-1)

It will be 6((6×5×4)-1)

= 6(120) -6

= 720 - 6

= 714

please click thanks and mark brainliest if you like :)

The sum of four consecutive odd integers is -72. Write an equation to model this situation, and ind the values of the four integ

Nutka1998 [239]

Answer:

equation: (x-3) +(x-1) +(x+1) +(x+3) = -72
values: -21, -19, -17, -15

Step-by-step explanation:

When dealing with consecutive integers, it often simplifies the problem to work with their average value. We know the average value of the integers in this problem is the even integer between the middle two. We can call it x, and write the equation ...

(x-3) +(x-1) +(x+1) +(x+3) = -72

This simplifies to ...

4x = -72 . . . . . . . we knew this before we wrote the above equation, since the sum of 4 numbers is 4 times their average.

x = -18 . . . . . . . . the middle number of the sequence

So, the numbers are:

-18-3 = -21
-18-1 = -19
-18+1 = -17
-18+3 = -15

_____

A more conventional approach is to define the variable as the integer at one end or the other of the sequence. If we make it be the lowest number, then the equation is ...

(x) +(x +2) +(x +4) +(x +6) = -72

and that simplifies to ...

4x +12 = -72 . . . . . collect terms

4x = -84 . . . . . . . . subtract 12

x = -21 . . . . . . . . . . divide by 4

Now, the other three numbers are found by adding 2, 4, and 6 to this one.

Adding and subtracting mixed numbers with unlike denominators

Agata [3.3K]

Answer:

Step-by-step explanation: You need to find a the lowest number that the denominators can be timed by. In you're case. You can just times 5 by 2 = 10

So that both the denominators are 10. And the denominator that was once 5. The numerator of that fraction also needs to be timed by 2.

So then you have 7 18/10 - 6 15/10

Then you can convert them to to proper fractions 8 8/10 - 7 5/10

Then you can take away the fractions so it's

8 8/10 - 7 5/10 = 1 3/10

Write the following in the ratio form a) 0.5 b) 0.6 c) 1.25 d) 3.4

alex41 [277]

Answer:

A) 1:2

B) 3:5

C) 5:4

D) 17:5

Step-by-step explanation:

Step 1) Convert the decimal number to a fraction

Step 2) Multiply the numerator and denominator by 10 to eliminate the decimal point.

Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF)

Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon

Heres an example. I'll do the last one.

3.4 = 3.4/1

(3.4 x10) /(1 x 10)= 34/10

34 /2 = 17

10/2 = 5

17/5 = 17:5
