Answer:

1.04167

Step-by-step explanation:

Z -score formula is given as

z = (x-μ)/σ, where

x is the raw score = 74

μ is the population mean = 69

σ is the population standard deviation = 4.8

Z score = x - μ/ σ

= 74 - 69/4.8

= 1.04167

The z score for a person is given as 1.04167

Answer:

A

Step-by-step explanation:

Find the mean:

Day 1: 2

Day 2: 1

Day 3: 4

Day 4: 5

Day 5: 0

Day 6: 7

Mean = [tex] \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17 [/tex]

This does not exceed a daily mean of 3.5 hours which was set by her mom as a guideline.

Therefore we can conclude that:

"Chawrdi complied with the guideline because the mean number of hours played is [tex] \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17 [/tex].

Step-by-step explanation:

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]

[tex]a = \sqrt{ {c}^{2} - {b}^{2} } [/tex]

Answer:

9 ÷ 15x

Step-by-step explanation:

( 52 - 43 ) /3x ( 2 + 3)

PEMDAS

Parenthesis, Exponents, Multiplication, Divison, Addition, Subtraction

Do the parenthesis first.....

52 - 43 = 9

9 ÷ 3x ( 2 + 3)

Parenthesis ( do the distributive property...multiply 3x by whatever is inside the parenthesis)

9 ÷ 3x × 2 + 3x × 3

9 ÷ 6x + 9x

Combine like terms (both x's)

9 ÷ 15x

You can't do anymore, since it is just an expression, and not an equation

Answer:

(7,12),(-12,-7)

Step-by-step explanation:

x^2 + y^2 = 193

x - y = - 5

x = y - 5

(y - 5)^2 + y^2 = 193

y^2 - 10y + 25 + y^2 = 193

2y^2 - 10y + 25 = 193

2y^2 - 10y + 25 - 193 = 0

2y^2 - 10y - 168 = 0

2*(y^2 - 5y - 84) = 0     This factors into

2*( y - 12) (y + 7) = 0

y = 12    

in which case x = 12 - 5 = 7

y = - 7

in which case x = -7 - 5 = - 12

25 + 144 = c^2

169 = c^2

Take the square root of both sides:

Answer:

4p-n+2q-3m is equivalent to 8p-3n+4q-9m

The expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression. which is the correct answer would be an option (C).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given in the question following:

8p - 3n + 4q - 9m

We have to determine the equivalent expression to the given expression

As per option (C), we have

⇒ 4(2p+ q) - 3(n+3m)

Apply the distributive property of multiplication,

⇒ 4 × 2p+ 4 × q  - 3 × n + 3 × m

⇒ 8p + 4q  - 3n + 3m

Rearrange the terms in the above expression,

⇒ 8p - 3n + 4q - 9m

So this expression is the same as the given expression.

Therefore, the expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression.

[tex]c=\sqrt{32}[/tex]

Step-by-step explanation:

When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and b we can plug that in to find out what c could be but we won't actually solve it.

[tex]a^2+b^2=c^2\\4^2+4^2=c^2\\16+16=c^2\\32=c^2\\\sqrt{c^2}=\sqrt{32}\\c=\sqrt{32}[/tex]

So c would equal whatever the square root of 32 is.

Answer:

we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage

Step-by-step explanation:

We are given;

Population proportion; p = 30% = 0.3

Sample proportion; p^ = 37% = 0.37

Sample size; n = 100

Let's define the hypotheses;

Null hypothesis; H0: p ≤ 0.3

Alternative hypothesis; Ha: p > 0.3

Formula for the test statistic is;

z = (p^ - p)/√(p(1 - p)/n)

Thus;

z = (0.37 - 0.3)/√(0.3(1 - 0.3)/100)

z = 0.07/0.04582575695

z = 1.53

From z-distribution table, at z=1.53 we have;

p-value = 1 - 0.9370 = 0.063

This p-value is greater than the significance level of 0.02 and thus we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage

Answer:

x = 4

Step-by-step explanation:

(10x + 9) + 34 + 97 = 180

10x +140 = 180

10x = 40

x = 4

The value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.

The sum of angles in a triangle can be used to determine the value of x in the given angles above.

m∠A + m∠B + m∠C  = 180 (sum of angles in a triangle)

10x + 9 + 34 + 97 = 180

10x + 140 = 180

10x = 40

divide both sides by 10;

x = 40/10

x = 4

Thus, the value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.
