Answer:

Step-by-step explanation:

The correct answer in this case would be A. There is only 1/8th percent chance of the spinner landing on 4.

There are 8 sections in the circle.  So our denominator will be 8.  We are looking to find how many 4s there are in the circle.  Since there is only ONE 4 in the circle, our nominator will be 1.  So, when we put that together, we get 1/8.

Answer:

1/8

Step-by-step explanation:

Given/To Find:

P(4)

Solve:

Since there are 8 number on the spinner. Which given us denominator will be 8.  And ONLY one of them is 4. Thus, Nominator will be 1.

Hence, that given us 1/8

Answer:

q = -4
q = -5/9

Step-by-step explanation:

Hi!

To solve this question, we can use the zero product property.

The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.

We have (q+4)(9q +5) = 0

That means either q + 4 = 0, or 9q + 5 = 0.

Solve:

We can check both cases:

(-4 + 4)(-36 + 5) = 0

0(-31) = 0

0 = 0

(-9/5 + 4)(9(-5/9) + 5) = 0

(2.2)(-5 + 5) = 0

(2.2)0 = 0

0 = 0

Answer:

x ≈ 44°

Step-by-step explanation:

        We will use a trigonometry function to solve for x. We can see that we have values for the adjacent side and hypotenuse. This means we will be using cosine. Cosine is [tex]\frac{adjacent }{hypotenuse}[/tex]

cos(x) =  [tex]\frac{adjacent }{hypotenuse}[/tex]        [Given]

cos(x) =  [tex]\frac{4.9}{6.8}[/tex]                   [Plug-in the values we have]

x ≈ 43.8969                 [Find the inverse cosine function of both sides]

Answer:

You ran a farther distance.

Step-by-step explanation:

First we will have to convert the 3.4 miles to km.

5.474 is greater than 5 km.

Therefore, you ran a farther distance.

Based on the absolute deviations and the predicted values, the sum of absolute deviations will be 4.8.

This can be found as:

= ∑ (Observed value - Predicted value)

The observed values are given in the table and the predicted values will be calculated using y = 3.6x - 0.4.

Solving gives:

=  [3 - (3.6 x 1 - 0.4)] + [7 - (3.6 x 2 - 0.4)] + [ 9 - (3.6 x 3 - 0.4)] + [14 - (3.6 x 4 - 0.4)] + [15 - (3.6 x 5 - 0.4)] + [21 - (3.6 x 6 - 0.4)] + [25 - (3.6 x 7 - 0.4)]

= 0.2 + 0.2 + 1.4 + 0 + 2.6 + 0.2 + 0.2

= 4.8

5 chocolate bars cost 3.15 (i don't have that currency symbol on my keyboard)

Step-by-step explanation:

First, let's find out what one costs, so it'll be easier.

3.80/6=0.63

Multiply the amount for one chocolate bar by five:

0.63*5=3.15

And there you go! 5 bars cost 3.15

I hope this helped!

Answer:

 £4.56

Step-by-step explanation:

5 chocolate bars= £3.80

1 chocolate bar= £3.80 / 5 = £0.76

Therefore, 6 chocolate bars= £0.76 x 6 =  £4.56

Kat is painting the four walls of her bedroom. She paints 52 square feet in 2/3 of an hour. How many square feet does she paint per hour?

78 sq. ft

★ 2/3 of an hour ⤏ 2/3 x 60 = 40 minutes

★ An hour ⤏ 60 minutes

Hence , kat can paint 78 sq. ft in an hour

Answer:

B. cos F = 9/41, cos E = 40/41

Step-by-step explanation:

use SOH CAH TOA

cosine is CAH which is adjacent over hypotenuse

the adjacent side to F is 9 and the hypotenuse is 41 so 9/41

the adjacent side to E is 40 and the hypotenuse is 41 so 40/41

We have given that the length of the football field = 300 feet

It can also be expressed as approximately  [tex]5.7\times 10^{n}miles[/tex]

Also, 1 mile = 5280 feet....(1)

We have to find 1 feet so divide both side of equation (1)by by 5280 we get,

[tex]1feet=\frac{1}{5280}[/tex]

Now, for 300 feet is,

[tex]300feet=\frac{1}{5280}(300)[/tex]

[tex]300 feet=0.056818181=0.057miles[/tex]

In scientific notation we have,

[tex]300 feet=5.7\times 10^{-2}miles[/tex]

Therefore we get  n = -2.

The probability that Kabita would take 2 red discs from the bags is 3/22.

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

The probability that Kabita would take 2 red discs = (number of red discs in bag 1 / total number of discs in bag 1) x  (number of red discs in bag 2 / total number of discs in bag 2)

Subsitute the required values,

[tex]\sf{ 60{\degree} + 20{\degree} + C = 180{\degree}}[/tex]

[tex]\sf{\angle{ B = 60{\degree}}}[/tex]

[tex]\sf{\sf{A + }}{\sf{\angle{B + }}}{\sf{ 100{\degree} = 180}}{\degree}[/tex]

[tex]\sf{\angle{ A + 60{\degree} = 180{\degree} - 100{\degree}}}[/tex]

[tex]\sf{\angle{ A = 80{\degree} - 60{\degree}}}[/tex]

Answer:

w = 60

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

w + 20 is an exterior angle of the triangle , then

w + 20 = w - 10 + w - 30

w + 20 = 2w - 40 ( subtract w from both sides )

20 = w - 40 ( add 40 to both sides )

60 = w

Answer:

w=60°

Step-by-step explanation:

triangle=180°

angle on a straight line=180°

using that,

we need to find the angle on the same line with that of "w+20°" angle, so we name it as "X"

so, 180-(w+20)=X

expand bracket by multiplying it with the "-"

so it'll be: 180-w-20=X

then rearrange to get like terms together

180-20-w=x

160-w=x

so the missing angle in the triangle is now (160-w)°

now using the angles in a triangle =180°

we add all the angles and equate it to 180, so:

w-30+w-10+160-w=180°

collect like terms again:

w+w-w-30-10+160=180

2w-w+120=180

w+120=180

move 120 to the other side and remember the sign changes, so:

w=180-120

therefore w=60°

now you can substitute w=60 into the triangle and see you'll get 180°

hope that helps
