The probability of eating both poisoned apples if you randomly eat 3 out of the five apples without replacement is 1/10 or 0.1.

To calculate this probability, we use the formula for combinations of n objects taken r at a time, (nCr) which is equal to n!/r!(n-r)!. In this example, n = 5 and r = 3, so the formula reduces to 5!/3!(5-3)! = (5*4*3)/(3*2*1) = 10. This means that there are 10 different combinations of 3 apples, out of the five, that can be chosen. Since only two of the apples are poisoned, the probability of eating both of the poisoned apples is 2/10 or 0.1.

Answer:

Yes. Both ratios can be reduced down to 1/2.

Step-by-step explanation:

Hope it helps!

For two numbers to be proportional, they need to be directly increasing or decreasing in a constant ratio.

To simplify these ratios, we can use division.

So, 7: 14 simplified is 1: 2.

So, 4: 8 simplified is 1: 2.

If these ratios are both simplified to equal 1 :2, they are proportional.

The number of sequences of length 10 that can be formed from the digits 1, 2, and 3 without repetition is 59,049.

The number of sequences of length 10 that can be formed from the digits 1, 2, and 3 without repetition is 3^10, or 59,049.

This is because for each of the 10 positions in the sequence, you have 3 choices: 1, 2, or 3, and since repetition is not allowed, the choices for each position are mutually exclusive.

Two occurrences are mutually exclusive or disjoint in logic and probability theory if they cannot occur at the same time. The set of outcomes of a single coin toss, which can result in either heads or tails but not both, is a good example.

Mutually exclusive is a statistical word that describes two or more occurrences that cannot occur at the same time. It is typically used to describe a circumstance in which the occurrence of one result takes precedence over the occurrence of the other. War and peace, for example, cannot exist together.

Step-by-step explanation:

a.) So he has 13 coins and those coins are nickels and quarters. If we let n be nickels and q be quarters

n + q = 13 because the total number of quarters plus nickels is 13

The coins have a total value of $2.05

Nickels are 0.05 cents and quarters are 0.25 cents, which means

0.05n + 0.25q = $2.05

Making your system of equations

[tex]n + q = 13 \\ 0.05n + 0.25q = 2.05[/tex]

Answer:

a.) So he has 13 coins and those coins are nickels and quarters. If we let n be nickels and q be quarters

Step-by-step explanation:

The linear equation is y = 20 + 2x and the complete table of values is

Kites purchased     Total cost

0                                      20

1                                      22

4                                      28

7                                     34

10                                   40

From the question, we have the following parameters that can be used in our computation:

Cost of kite = $20 for shopping and $2 per kite

When this is represented as an equation, we have

y = 20 + 2x

Where x = the number of kites purchased

Using the above as a guide, we have the following:

When x = 4

y = 20 + 2 * 4 = 28

When x = 7

y = 20 + 2 * 7 = 34

When x = 10

y = 20 + 2 * 10 = 40

So, the missing entries are $28, $34 and $40

Answer:

Step-by-step explanation:

The equation to find the cost of each pair of shorts is 175 = 75 + 5x where each short cost $20

Cost of jackets= $75

Number of shorts= 5

Cost of each short = x

Total amount Jim spent= $175

Total amount Jim spent = Cost of jackets + (Number of shorts × Cost of each short)

175 = 75 + 5x

subtract 75 from both sides

175 - 75 = 5x

100 = 5x

divide both sides by 5

x = 100/5

The average number of pairs of jeans owned by students in the sample can be calculated by taking the sum of the jeans owned by all students in the sample and dividing it by the number of students in the sample.

The sampling method used in this data collection is cluster sampling. Cluster sampling is a probability sampling technique that divides the population into separate groups or clusters and randomly selects a number of those clusters to be included in the sample. In this case, the population would be the students in the algebra class, and the clusters would be the individual students. Using a simple random sampling technique, the interviewer would select a certain number of students from the class and ask them how many pairs of jeans they own. The average number of pairs of jeans owned by the students in the sample would then be calculated by adding together the number of jeans owned by all of the students in the sample, and then dividing by the number of students in the sample.

Average number of pairs of jeans owned by students in sample = (Sum of jeans owned by all students in sample) / (Number of students in sample)

The average number of pairs of jeans owned by students in the sample can be calculated by taking the sum of the jeans owned by all students in the sample and dividing it by the number of students in the sample.

What is a fraction ?

In Maths, a fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator.

Given :

1 cup = 8 fluid ounces

Cups that holds 56 ounces of water = 56/8 [Since, 1 cup = 8 fluid ounces]

Cups that holds 56 ounces of water = 7

Cups that holds 56 ounces of water = cups that water bottle can hold

Trigonometric functions are real functions in mathematics that connect an angle of a right-angled triangle to ratios of two side lengths. They are widely utilized in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many more.

There are six expressions of an angle that are often used in trigonometry. Their names and acronyms include

For A)

Sin(55) = cos (θ)

sin (55)= sin(90-θ)

Compare both sides

55 = 90 - θ

θ = 90 - 55

θ = 35°

For B)

Sin(θ) = Cos (28)

angle θ would be  Arc sin (cos (28))

The Values of x, y, and z will be  40, 43, and 97 for the given quadrilateral.

A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.

Given a parallelogram ABCD that has ∠A = y + ?, ∠B  = z, ∠C  =43 + x. and  ∠D = 97

In parallelogram opposite sides are Equal

thus,

z = 97

So, ∠B = 97

Since AD and BC are parallel

y will be the inner vertex angle of these lines

Thus,

y = 43

And Since, Sum of all angles in a triangle is 180 degrees.

For triangle ADC

97 + x + y = 180

Substitute the value of y

97 + 43 = 180

x = 40

therefore, the Values of x, y, and z will be  40, 43, and 97 for the given quadrilateral.

Correlation: Correlation analysis is used to gauge how strongly two variables are related. The symbol for the correlation coefficient is r.

Shape: Whether the data points follow a linear pattern or some other complex curves is indicated by the association's form. If it seems that a line would adequately summarise the overall trend in the data, then do so. The relationship between the two variables is then linear.

The appropriate statement can be found below:

The determination of the standard deviation between the two variables influences how a least-squares linear regression function slopes, and in a similar way, how the sample correlation coefficients are interpreted.

Serena needs 12 grams of the 40% solution and 8 grams of the 70% solution.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given Serena is making an experiment. for that, she needs 20 grams of a 52% solution of salt, one with 40% and the other with 70% of salt in them,

let her need x grams of the 40% solution and y grams of the 70% solution.

so x + y = 20.......(1)

and 0.40x + 0.40y = 20(0.52)

0.40x + 0.70y = 10.4

from equation 1 we get x = 20 - y

substitute in the equation 0.40x + 0.70y = 10.4

0.40(20 - y) + 0.70y = 10.4

8 - 0.40y + 0.70y = 10.4

0.30y = 10.4 - 8

y = 2.4/0.30

y= 8 grams

and x = 20 - 8 = 12 grams

Hence she use 12 grams of 40% solution and 8 grams of 70% solution.
