1/10 of the m&m in the bag are red and 1/5 are blue. What fraction of alll the m&m are red and blue
Step-by-step explanation:
we need to bring them to the same denominator. in this case : 10
so, 1/10 of everything are red.
1/5 = 2/2 × 1/5 = 2/10 of everything are blue.
so, we now just add these two :
1/10 + 2/10 = 3/10
so, 3/10 are red and blue (rather red or blue, because none are red and blue)..

The probability distribution that she or he is on duty on Saturday or Sunday will be 0.7
What is probability distribution ?
A frequency distribution that has been idealised is a probability distribution.
An individual sample or dataset is described by its frequency distribution. It's the number of times in the dataset that each potential value of a variable appears.
The probability of occurrence of a value determines how frequently it appears in a sample. Probability is a value between 0 and 1 that indicates the likelihood that something will happen:
Zero denotes impossibility.1 denotes a certainty.A value will occur more frequently in a sample the higher its likelihood.
The probability of a value is more particularly the relative frequency in an indefinitely large sample.
Probability distributions are theoretical since it is not feasible to obtain infinitely large samples in practise.
They are idealised frequency distributions that are intended to represent the population from which the sample was taken.To characterise the populations of real-world variables, such as coin tosses or the weight of chicken eggs, probability distributions are utilised. They are also used to calculate p values in hypothesis testing.Let the people work on Sunday = sun = 4
Let the people work on Saturday = sat = 3
total no. of doctors are 10
so the probability distribution of people work on either Sunday or Saturday will be :
= Sun + sat / total no of doctors
= 3+4/10

Following is the geometric progression of Nelson's debt after each month: (E) 950,967.1, 984.51, 1002.23, 1020.27
What is a geometric sequence?A geometric progression sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.
So, in this issue, the interest rate is as follows: 1.8%.
The debt will therefore be equal to the debt from the previous month multiplied by 100 + 1.8 = 101.8% = 1.018 each month, and the common ratio is as follows: 1.018.
In light of this, the terms of the series are as follows:
2nd term: 950 x 1.018 = $967.1
3rd term: 967.1 x 1.018 = $984.51
4th term: 984.51 x 1.018 = $1002.23
5th term: 1002.23 x 1.018 = $1020.27
Therefore, the following is the geometric progression of Nelson's debt after each month: (E) 950,967.1, 984.51, 1002.23, 1020.27

n a coordinate plane, Triangle XYZ is rotated 90 degrees counterclockwise about the origin to form Triangle X'Y'Z'. Which conclusion is always true?
△X'Y'Z' is transformed form △XYZ. If △XYZ rotated 90 degrees counterclockwise about the origin, then YZ ⊥ Y'Z'. Hence option B is the correct option.
What is transformation?
A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Given that,
△XYZ is rotated 90 degrees counterclockwise about the origin to form △X'Y'Z'.
Each side of △XYZ is rotated 90 degrees counterclockwise.
Then the angle between corresponding sides of △XYZ and △X'Y'Z' are 90 degrees.
Therefore
XY⊥X'Y'
YZ ⊥Y'Z'
ZX ⊥ Z'X'.

At a distance of 6 meters, a person with average vision is able to clearly read letters 1.0 cm high.Approximately how large do the letters appear on the retina? (Assume that the retina is 1.7 cm from the lens.)
The size of the letters appear on the retina is 0.00289 cm
Given data:
To determine the size of the letters on the retina, use the concept of angular size and the relationship between object size, distance, and angular size.
Angular size is the measure of the angle subtended by an object as seen from a particular point, in this case, the eye.
Angular size = Object size / Distance
Object size = 1.0 cm
Distance = 6 meters
Angular size = 1.0 cm / 6 meters
To convert the distance to centimeters, multiply by 100:
Angular size = 1.0 cm / (6 meters * 100 cm/meter)
Angular size = 1.0 cm / 600 cm
Angular size = 0.0017 radians
The angular size of the letters is 0.0017 radians.
Now, to determine the size of the letters on the retina, calculate the linear size on the retina using the angular size and the distance from the lens to the retina.
Linear size on retina = Angular size * Distance from lens to retina
Angular size = 0.0017 radians
Distance from lens to retina = 1.7 cm
Linear size on retina = 0.0017 radians * 1.7 cm
Linear size on retina ≈ 0.00289 cm
Hence, the letters appear to be approximately 0.00289 cm in size on the retina.

What is the rate of change low of the distance in the feet below sea level with respect to time that the box submarine traveled?
The rate of change of the distance with respect to time that the box submarine traveled is 11 feet per second
How to determine the rate of change of the distance with respect to time the box submarine traveled?A rate of change describes how one quantity changes in relation to another quantity.
Mathematically, it is defined as the change in one quantity divided by the change in the other quantity.
In this case, we have:
rate of change = change in distance / change in time
Use the data in the table:
rate of change = 545-380/15-0
rate of change = 165/15 = 11

in a wildlife park, there were 20 gray wolves. after a few years, there were 38 gray wolves what is the percent gain
The percent gain in the number of wolves is 90%.
How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
From the information, in a wildlife park, there were 20 gray wolves. after a few years, there were 38 gray wolves.
The percent gain will be:
= Increase in wolves / Previous number × 100
= (38 - 20) / 20 × 100
= 18/20 × 100
= 90%
Therefore, it should be noted that based on the information illustrated above, the percentage gain will be 90%.

2x - 5y = 14
y = 3x+5
Answer:
x = -3
y = -4
Step-by-step explanation:
2x - 5y = 14 ⇒ ( 1 )
y = 3x + 5 ⇒ ( 2 )
First, let us find the value of x.
For that let us use equation ( 1 ) and replace y with (3x + 5 ).
2x - 5y = 14
2x - 5 ( 3x + 5 ) = 14
Solve the brackets.
2x - 15x - 25 = 14
Combine like terms.
-13x - 25 = 14
Add 25 to both sides.
-13x = 14 + 25
- 13x = 39
Divide both sides by -13.
x = -3
Let us find the value of y.
For that, use equation (2) and replace x with (-3).
y = 3x + 5
y = 3 × -3 + 5
y = - 9 + 5
y = -4
At a restaurant, there are three different appetizers on the menu: spring rolls, chicken tenders, and pretzel dippers. One group buys 2 plates of chicken
tenders and 1 plate of pretzel dippers, and spends $23 on appetizers. Another group spends $30.75 to buy 3 plates of spring rolls and a plate of chicken
tenders. A third group buys one of each appetizer, spending $22.25 on appetizers.
How much does a plate of spring rolls cost?
A. $7.75
B. $8.50
C. $7.50
D. $6.50
Answer: A
Step-by-step explanation: To solve this problem, we can set up a system of equations to represent the information given in the problem. Let x represent the cost of a plate of spring rolls, y represent the cost of a plate of chicken tenders, and z represent the cost of a plate of pretzel dippers.
The first group spent $23 on 2 plates of chicken tenders and 1 plate of pretzel dippers, so the equation for this group is:
2y + z = $23
The second group spent $30.75 to buy 3 plates of spring rolls and 1 plate of chicken tenders, so the equation for this group is:
3x + y = $30.75
The third group spent $22.25 on one of each appetizer, so the equation for this group is:
x + y + z = $22.25
Now that we have three equations, we can use algebraic techniques to solve for the value of x, which represents the cost of a plate of spring rolls.
First, we can solve the second equation for y:
y = $30.75 - 3x
Substituting this expression for y into the first equation, we get:
2($30.75 - 3x) + z = $23
Solving for x, we find that x = $7.75.
Therefore, the cost of a plate of spring rolls is $7.75, so the answer is A.
