Using the data from the theoretical probability table, what is the probability of the spinner landing only once on yellow in two spins? 0.0625 0.5625 0.375 1
The probability of the spinner landing only once on yellow in two spins is 0.375. Then the correct option is C.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
The total sample will be
Total sample = 16 {RR, BB, YY, GG, RB, BR, RY, YR, RG, GR, BY, YB, BG, GB, YG, GY}
The probability of the spinner landing only once on yellow in two spins will be
Favorable event = 6 {YR, RY, YG, GY, YB, BY}
Then probability will be
[tex]P = \dfrac{6}{16}\\\\P = 0.375[/tex]

Sally, Emma and James have a total of 52 nerf toys. If James had 6 more, then he would have as many as both girls combined. Emma has three more toys than Sally. How many nerf toys do each of the three have.
(Please answer quickly it's due tomorrow morning)
Answer:
emma: 6 toys, sally: 13 toys, james: 23 toys
Step-by-step explanation:
if emma had x toys, sally would have (x-3) toys. and we know that if james had 6 more toys, he would have the same amount as both girls combined. so in this case in terms of x, james would have (x+x-3-6) toys, after simplification we get 2x-9 toys..
since we know that the three of them have 52 nerf toys as total, we can set up the equation:
x= number of toys emma has
2x-9+x+x-3=52
4x-12=52
x=16
emma has 16 toys, and sally has (16-3)=13 toys. finally, james has (2*16-9)=23 toys. 16+13+23=52
Helpppp ASAPS i need your help i give brainlist to the correct answer only the question 2 and 3
Answer:
1. 9
2. 25
3. No (Explanation below)
Step-by-step explanation:
1. Original PT Formula is c=√a²+b²
BUT you're looking for the leg so you now have the formula of a=√c²-b² *c being the hypotenuse
a= √ 15² - 12²
a= √ 225 - 144
a= √81
a= 9
2. 16 + 9 = 25
* you're not looking for an angle therefore you are most likely looking for the length of the side. Simply add the AD and DC together to get the answer. If you were looking for an angle it'll be 180°.
3. NO because a right angle is an angle of exactly 90°, whether it be at a corner of a square/rectangle, a triangle, or where two perpendicular lines intersect. Angle ABC is an obtuse angle as it measures more than 90°

Steve said that [5, 12) is the interval notation that represents the set of all real numbers greater than or equal to 5 and less than 12. Joe says that (5, 12] is correct interval notation. Who is correct and justify why?
Answer:
Steve was correct in his statement.
Step-by-step explanation:
According to standard notation, opening bracket ( [tex][[/tex] ) represents the lower bound of a set so that elements of the set are equal or greater than lower bound. In addition, closure parenthesis ( [tex])[/tex] ) represents the upper bound of a set so that element of the set are less than upper bound.

15% of y is 30 what equation could be used to solve
Answer:
Y= 200
Step-by-step explanation:
Just divide 30 by 0.15
Hope that helps!
Answer: y = 30/0.15
Step-by-step explanation:
First, convert 15% to a decimal by dividing by 100 to get 0.15. The word "of" in an equation means multiply, so the equation would be y*0.15 = 30. To isolate the variable you're trying to solve for, divide both sides by 0.15. The 0.15 on the left side of the equation cancels out, leaving you with a final equation of y = 30/0.15.

(100 points;)The area of a right triangle is 39.6 in², and the base of the triangle is 12 inches.
Which of the following values is the height of the triangle?
303 in.
1.65 in.
6.6 in.
6.1 in.
The answer is 6.6 inches
AREA OF TRIANGLE = 1/2 X BASE X HEIGHT
=> 39.6=12XH/2
=> 39.6X2=12XH
=> 79.2 = 12XH
=> 79.2/12= H
=> 6.6
Solution:
Given:
Area of right triangle = 39.6 in²Base of triangle = 12 inArea of triangle formula: 1/2 x Base x Altitude
Substitute the area and the base:
1/2 x Base x Altitude = Area of right triangle1/2 x 12 x Altitude = 39.6 in²Simplify the LHS:
1/2 x 12 x Altitude = 39.6 in² 6 x Altitude = 39.6 in²Divide 6 both sides:
(6 x Altitude)/6 = 39.6/6Altitude = 6.6 in.please help me to solve these simple math

Hey there!
In order to simplify this expression, we need to combine like terms.
Remember, like terms are terms from the same "family". not terms that you like. :)
So, the like terms here are
8x, 3x
and
-3y and -2y
Combine them:
8x-3x-3y-2y

We have,
Number of pineapples = 2
Amount given = £5
Amount returned = £3.60
The cost of the two pineapples.
= 5 - 3.60
= £1.40
The cost of one pineapple.
= 1.40/2
= 140/200
