Answer:

The value of x - y is 14

Step-by-step explanation:

∵ x : y = 5 : 3

→ Write it in the form of the fraction

∴ [tex]\frac{x}{y}=\frac{5}{3}[/tex]

→ Multiply both sides by y

∴ [tex]\frac{x}{y}[/tex] × y = [tex]\frac{5}{3}[/tex] × y

∴ x =  [tex]\frac{5}{3}[/tex] y ⇒ (1)

∵ x + y = 56 ⇒ (2)

→ Substitute x in (2) by (1)

∴  [tex]\frac{5}{3}[/tex] y + y = 56

→ Add the like terms

∵  [tex]\frac{8}{3}[/tex] y = 56

→ Divide both sides by  [tex]\frac{8}{3}[/tex]

∴ y = 21

→ Substitute the value of y in (1) to find x

∵ x =  [tex]\frac{5}{3}[/tex] (21)

∴ x = 35

→ Now find the value of x - y

∵ x - y = 35 - 21

∴ x - y = 14

∴ The value of x - y is 14

Step-by-step explanation:

Given that the total number of time that you have been waiting is 1 hour

which is equivalent to 60minutes which is the sample space

and the sample size which is 10 minutes.

then the probability of a taxi arriving in 10minutes seeing that you have been waiting for over 60minutes is

Pr(taxi arrives in 10 min)= 10/60= 1/6

thus the probability is 1/6

Answer:  Experimental studies directly influence something to see its effect, but observational studies do not directly influence the subjects.

Step-by-step explanation:

The correct option is D.

In an experimental study, you perform an experiment. In an experiment are made with the objective of validating, refute, or support a given hypothesis, where you observe "what happens" when you modify a given set of parameters. Always in an experiment, we can define the independent and dependent variables, where the independent are the ones that we can modify at will, and the dependent ones are the ones that we observe to see how they react to the changes in the independent variables.

In observational studies, the idea is not changing anything in the object of study, so the scientist in this case are only observers or spectators.

Answer:

[tex]\dfrac{11}{8}[/tex]

Step-by-step explanation:

A restaurant served a total of 1/2 of a loaf of wheat bread and 7/8 of a loaf of white bread.

We need to find how many loaves were served in all. It is equal to the sum of the fraction of 1/2 and 7/8.

Sum of these two fractions :

[tex]\dfrac{1}{2}+\dfrac{7}{8}\\\\=\dfrac{4+7}{8}\\\\=\dfrac{11}{8}[/tex]

So, a total of 11/8 were served in all.

Step-by-step explanation:

From the diagram attached, the divison operation represented by the model is [tex]\frac{7}{4} \div \frac{1}{2} = 3 \frac{1}{2}[/tex]

The Fraction of shaded partitions = 7(1/4) = 7/4

Half of each rectangle is circle = 1/2

Hence, the divison exemplified by the model is :

Fraction of shaded partition ÷ Circled portion

[tex]\frac{7}{4} \div \frac{1}{2}[/tex]

Take the reciprocal of 1/2 and change sign to multiplication :

[tex]\frac{7}{4} \times \frac{2}{1} = 3 \frac{1}{2}[/tex]

Therefore, the division problem represented by the model is [tex]\frac{7}{4} \div \frac{1}{2} = 3 \frac{1}{2}[/tex]

A. 2, 4

B. 4, 4

C. -1, -4

Step-by-step explanation:

Because in mathematics, a reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis or plane of reflection. The image of a figure by a reflection is its mirror image in the axis or plane of reflection.

So for A. just reflect the point over or "across the x-axis."

For B. just reflect the point over or "across the x-axis."

And for C. just reflect the point over or "across the y-axis."

Overall, what the associative property is is moving the parenthesis elsewhere.  You just group two different numbers of the equation.

The equation that makes the original equation much easier to evaluate is D. (8×1/2)1/3, since 8×1/2 is 4 and now you just multiply 4 with 1/3.

5 / 14

Step-by-step explanation:

Given that:

Number of parrots shipped = 8

Number of defective parrots = 2

Number of Random samples tested = 4

Number of healthy parrots = 8 - 2 = 6

Probability that first 3 parrots are healthy:

P(1st parrot) * p(2nd parrot) + p(3rd parrot)

P = (number of required outcomes / number of total possible)

USing sampling without replacement :

P(1st parrot healthy ) = 6/ 8 = 3/4

P(2nd parrot healthy) = 5 / 7

P(3rd parrot healthy) = 4 / 6 = 2/3

P(first 3 parrots being healthy) :

(3/4) * (5/7) * (2/3) = 30/84 = 5 / 14

Answer:

y = -4x + 6

Step-by-step explanation:

To solve for y in terms of x, isolate y.

To get y by itself, subtract 4x from both sides:

4x + y = 6

y = -4x + 6

So, y in terms of x is y = -4x + 6

Step-by-step explanation:

Let X number of chocolate chips apiece of cookie.

The mean number of chocolate chips apiece is λ = 8.
