There is A Spinner That Have 8 Space 1-8 What Is The Probability That Te Spinner Will NOT Land On 5 or 8?

insens350 [35]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

<u>Key skills needed: Probability, Possible Outcomes</u>

1) We are given a spinner --> With numbers: 1,2,3,4,5,6,7, and 8

That means there are 8 numbers on the spinner.

2) The problem asks what is the probability that the spinner will not land on 5 or the 8.

To calculate this --> $\frac{acceptedoutcomes}{total}$

3) The accepted outcomes are when the spinner lands on --> 1,2,3,4,6,7

That is 6 accepted outcomes.

4) The total outcomes is 8 (since there are numbers the spinner can land on).

5) Therefore, the answer would be $\frac{6}{8}$

$\frac{6}{8}$ can be simplified into $\frac{3}{4}$ as both the numerator (6) and the denominator (8) share a factor of 2.

6) With this --> $\frac{3}{4}$ is the answer.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =

andrey2020 [161]

we have

$f(x)=x^{2}-2x-3$

Find the roots

Equate the function to zero

$x^{2}-2x-3=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2}-2x=3$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$x^{2}-2x+1=3+1$

$x^{2}-2x+1=4$

Rewrite as perfect squares

$(x-1)^{2}=4$

Square root both sides

$(x-1)=(+/-)2$

$x=1(+/-)2$

$x=1+2=3$

$x=1-2=-1$

therefore

<u>the answer is</u>

$x=3$

A triangle has a base of 3⅖ inches and an area of 5⅒ square inches. Find the height of the triangle. Show your reasoning

N76 [4]

Answer: 3 in.

Step-by-step explanation:

Given

The base of the triangle is $3\frac{2}{5}\ inches$

The area of the triangle is $5\frac{1}{10}\ inches^2$

Solve mixed fraction

Base is

$=3\dfrac{2}{5}\\\\=\dfrac{17}{5}\ in.$

Area is

$=5\dfrac{1}{10}\\\\=\dfrac{51}{10}\ in.^2$

The area of the triangle is given by

$\Rightarrow \text{Area A=}\dfrac{1}{2}\times \text{base}\times \text{height}$

Insert the values to get the height

$\Rightarrow \dfrac{51}{10}=\dfrac{1}{2}\times \dfrac{17}{5}\times \text{height}\\\\\Rightarrow \text{height}=3\ in.$
