$\frac{2}{8}$ of students only saw jewelry collection

Solution:

Given that, On a class trip to the museum,5/8 of the students saw the dinosaurs

7/8 of the students saw either the jewelry collection or the dinosaurs

To find: Fraction of students only saw jewelry collection

From given statement,

Fraction of students saw dinosaur = $\frac{5}{8}$

Fraction of students saw either the jewelry collection or the dinosaurs = $\frac{7}{8}$

Therefore,

Fraction of students only saw jewelry collection = Fraction of students saw either the jewelry collection or the dinosaurs - Fraction of students saw dinosaur

$\rightarrow \frac{7}{8} - \frac{5}{8} = \frac{7-5}{8} = \frac{2}{8}$

Thus $\frac{2}{8}$ of students only saw jewelry collection

What is the missing angle measure?

Evgen [1.6K]

Answer:

x = 33

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for x

x = 180 - (90 + 57) = 180 - 147 = 33

Jasmine created this spinner to predict whether a randomly selected student in her school will be traveling during the upcoming

777dan777 [17]

Answer:

The number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.

Step-by-step explanation:

The spinner created by Jasmine, to predict whether a randomly selected student in her school will be traveling during the upcoming holiday break, has 8 equal sections labeled:

{yes, yes, no, no, no, no, no, no}

So, there are two sections labeled yes and six labelled as no.

Compute the probability of a yes as follows:

$P(\text{yes})=\frac{2}{8}=0.25$

Jasmine selected n = 36 students in her gym class.

If a student in her school will be traveling during the upcoming holiday break is independent of the other students.

Let the random variable X be defined as the number f students that will be traveling during the upcoming holiday break.

The random variable X follows a Binomial distribution with parameters n = 36 and p = 0.25.

Compute the expected value of X as follows:

$E(X)=np\\=36\times 0.25\\=9$

Thus, the number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.

PLEASE HELP! I will mark brainliest!

Answer:

D

Step-by-step explanation:

Instead of going through each of the table, let's create one ourselves.

So, we have the piecewise function:

$f(x)=-x+8,\text{ if } x$

So, let's create a table of values starting with 2 and skipping the odd numbers until 12.

2:

For 2, since 2 is less than one, plug it into the first equation. Thus:

$f(2)=-(2)+8=6$

So, the first value is (2,6).

For 4, since 4 is not less than 4 but rather equal to 4, use the second equation. Thus:

$f(4)=(4)=4$

The second value is (4,4).

For 6, the same thing. 6 is greater than 4 so use the second equation:

$f(6)=(6)=6$

So the third value is (6,6).

And this pattern will repeat. Therefore, our table of equations is:

x | y

2 | 6

4 | 4

6 | 6

8 | 8

10 | 10

12 | 12

The choice that represents this is D. D is the correct answer.
