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.

Answer:

$\angle B=41.81^\circ$

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

$\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}$

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

$\displaystyle \sin \angle B=\frac{2}{3}=0.667$

Calculating the inverse sine function:

$\angle B=\arcsin (0.667)$

$\boxed{\angle B=41.81^\circ}$

What is the value of w?

Dima020 [189]

You do 65+90=155
then 180-155=25 to get the angle next to w
w=155

Calculate how much each size per gram, and circle which gives the best value for money. 250g for $2.30, 400g for &3.40, 1Kg

Bezzdna [24]

To do this, we must set up ratios:
Option One:
$\frac{2.30}{250g} \\ \frac{0.0092}{1g} \\ 0.0092/g$
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
$\frac{3.40}{400g} \\ \frac{0.0085}{1g} \\ 0.0085/g$
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three:
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
$\frac{5.65}{1000g} \\ \frac{0.00565}{1g} \\ 0.00565/g$
The third option costs $0.00565/gram.

Therefore, option three is the cheapest!

Hope this helps!

Identify the rule that could possibly describe this set of data.

Elina [12.6K]

option D is the correct option

y= 10- 2x

Now, if we take the first value of x i.e 1

then, y= 10-2(1)

= 10-2 = 8 ---------> this value matches with the given value of y

take,x =2

y=10-2(2) = 10-4 = 6--------->this value matches with the given value of y

taking, x = 3

y= 10-2(3) = 10- 6=4-------->this value matches with the given value of y
