but $45 multiplyed by 2 would equal $90 with a remainer of $30 (jason could buy some McDonlads with that money , lol)

Answer:

It is known that the variance of a popualtion equals 1,936.

Step-by-step explanation:

That should be correct!!!

There is a 0.95 probability that the sample mean will provide a margin of error of 7.84.

The term probability refers to the likelihood of an event occurring.

Given that;

The variance of a population = 1,936

And, A random sample of 121 has been taken from the population.

Now,

Since, Standard deviation = √ Variance

                                        = √1,936

                                        = 44

Hence, The standard error = 44 / √121

                                         = 44 /11

                                         = 4

We know that;

The critical z factor for a confident interval of 0.95 = ± 1.96

Thus, The sample mean will provide a margin of error = 4 × 1.96

                                                                                    = 7.84

Step-by-step explanation:

The correct statements about triangle PQR.are given by options A), B), and F) and this can be determined by using the trigonometric functions.

Given :

In triangle PQR, angle P is 60°, angle Q is 30° and angle R is 90°.

The trigonometric functions can be used in order to determine the correct statements about triangle PQR.

[tex]\rm sin30 = \dfrac{PR}{QP}[/tex]

[tex]\rm PQ = 2\;PR[/tex]

[tex]\rm cos30 = \dfrac{QR}{QP}[/tex]

[tex]\rm PR=\dfrac{\sqrt{3} }{2}\;PQ[/tex]

[tex]\rm tan30 = \dfrac{PR}{QR}[/tex]

[tex]\rm \sqrt{3}\; PR= QR[/tex]

[tex]\rm sin60 = \dfrac{QR}{PR}[/tex]

[tex]\rm QR=\dfrac{\sqrt{3} }{2} \;PR[/tex]

[tex]\rm cos60 = \dfrac{PR}{QP}[/tex]

[tex]\rm PR=2\;PQ[/tex]

[tex]\rm tan60 = \dfrac{QR}{PR}[/tex]

[tex]\rm PR=\sqrt{3} \; QR[/tex]

Therefore, the correct option A), B), and F).

Answer:

Y = 5.5x

The constant is 5.5

since no matter what y and x are there will always be a 5.5 difference

Also mark brainliest please

The required constant of proportionality is 5.5 in the given expression.

Given that,
The equation y = 5.5x represents a proportional relationship. What is the constant of proportionality is to be determined.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
The given proportion equation is,?
y = 5.5x
Where y is the dependent variable and x is the independent variable,
And 5.5 is contant.

Thus, the required constant of proportionality is 5.5 in the given expression.

Step-by-step explanation:

Answer:

9x - 2x + 62 = 9x + 24

Number of correct answer each obtained = 19

Step-by-step explanation:

Given that:

Number of correct answers = x

POINTS for correct answers = 9

POINTS for incorrect answers = - 2

SCHOOL A:

Number of correct answers = x

Number of incorrect answers = x

Initial point = 62

Initial point + 9(number of correct answers) + - 2(number of incorrect answers)

62 + 9x - 2x

SCHOOL B :

Number of correct answers = x

Number of incorrect answers = 0

Initial point = 24

Initial point + 9(number of correct answers) + - 2(number of incorrect answers

24 + 9x

Since they end up tied :

School A = School B

62 + 9x - 2x = 24 + 9x

9x - 2x + 62 = 9x + 24

Number of correct answers gotten :

9x - 2x + 62 = 9x + 24

7x + 62 = 9x + 24

7x - 9x = 24 - 62

-2x = - 38

x = 19

Hence, Number of correct answers each obtained = 19

Answer:

(a) Not independent

(b) The probability the woman has a Bachelor's Degree and has never married is 0.046.

Step-by-step explanation:

Denote the events as follows:

X = American women aged 25 years or older have a Bachelor's Degree

Y = American women aged 25 years or older have never married

The information provided is as follows:

P (X) = 0.202

P (Y) = 0.165

P (X | Y) = 0.228

P (Y | X) = 0.186

(a)

If two events, say A and B are independent then,

P (A|B) = P (A) and P (B|A) = P (B)

Since,

P (X | Y) ≠ P (X)

P (Y | X) ≠ P (Y)

The events "have a Bachelor's Degree" and "never married" are not independent.

(b)

Compute the probability the woman has a Bachelor's Degree and has never married as follows:

[tex]P(X\cap Y)=P(X|Y)\times P(X)\\\\=0.228\times 0.202\\\\=0.046056\\\\\approx 0.046[/tex]

Thus, the probability the woman has a Bachelor's Degree and has never married is 0.046.

Step-by-step explanation:

Answer:

∴ The expression which is equal to 64 x 13 is (60 × 13) + (4 × 13) ⇒ C

Step-by-step explanation:

The product of two numbers can be put in the form of the sum of two products by using this rule, m × n =  (a × n) + (b × n), where m = a + b

Let us solve the question using this rule

∵ We need to put 64 × 13 as the sum of two products

→ Let m = 64 and n = 13

∵ m = 64 and n = 13

∵ 64 = 60 + 4

∴ a = 60 and b = 4

→ By using the rule above

∵ m × n = (a × n) + (b × n)

∵ a = 60, b = 4, and n = 13

∴ 64 × 13 = (60 × 13) + (4 × 13)

∴ The expression which is equal to 64 x 13 is (60 × 13) + (4 × 13)
