Answer:

[tex]Probability = \frac{11}{40}[/tex]

Step-by-step explanation:

Given

See attachment

Required

The probability that a 7th grader selected will play guitar.

From the attachment, we have:

[tex]7th\ graders =11+8+8+13[/tex]

[tex]7th\ graders =40[/tex]

7th graders that can play guitars are:

[tex]Guitars = 11[/tex]

So, the probability is:

[tex]Probability = \frac{Guitars}{7th\ graders}[/tex]

[tex]Probability = \frac{11}{40}[/tex]

Answer:

Step-by-step explanation:

If p varies jointly as m and r, then;

p = kmr

k is the proportionality constant

Given that p = 180, m = 5 and r = 8

180 = k(5)(8)

180 = 40k

k = 180/40

k = 4.5

To get m when p = 324 and r = 6

324 = 4.5(m)(6)

324 = 27m

m = 324/27

m = 12

Hence the value of m is 12

Answer:

x > 3

Step-by-step explanation:

Simply isolate the inequality to get a equivalent inequality. Treat the sign > like an equal sign, what you do to one side, you do to the other side of the inequality.

Isolate the variable, x. Divide 2 from both sides of the equation:

(2x)/2 > (6)/2

x > 6/2

x > 3

x > 3 is your equivalent inequality.

Answer:

0.527

Step-by-step explanation:

From the question,

The sequence is Geometry Progression (G.P)

Tₙ = arⁿ⁻¹.......................... Equation 1

Where n = number of term, a = first term, r = common ratio

Given: n = 7, a = 6, r = 2/3

Substitute these values into equation 1

T₇ = 6(2/3)⁷⁻¹

T₇ = 6(2/3)⁶

T₇ = 6(64/729)

T₇ = 384/729

T₇ = 0.527

Hence, the 7th term of the sequence is 0.527

Answer:y = x 2 − 12 x The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: ( − ∞ , ∞ ) Set-Builder Notation: { x | x ∈ R } The range is the set of all valid y values. Use the graph to find the range. Interval Notation: [ − 36 , ∞ ) Set-Builder Notation: { y | y ≥ − 36 } Determine the domain and range. Domain: ( − ∞ , ∞ ) , { x | x ∈ R } Range: [ − 36 , ∞ ) , { y | y ≥ − 36 }

Step-by-step explanation:

Answer:

Step-by-step explanation:

There is no restriction upon x so the domain is all real numbers

x=(-oo, +oo)

y has a minimum value when x=12 and y=11. Any other value of x increases the value of y. So the range is all real numbers greater than or equal to 11.

y=[11, +oo)

Answer:

b and d

Step-by-step explanation:

2(5x+2+x)=12x+4(b)

2(6x+2)=12x+4

First, solve the expression.

2(5x+2+x)

10x+4+2x

12x+4

So we know that one of the answers is B. and not A.

C. 2(5x+3)

10x+6

D. 2(6x+2)

12x+4

So the answers are B and D, or option B

Answer:

4) D) 20

3) A) 16°

Step-by-step explanation:

4)

You must follow the correct order of operations.

13 - 2(1 - 15)/4 =

Do the subtraction inside the parentheses first.

= 13 - 2(-14)/4

Now multiply -2 by -14.

= 13 + 28/4

Divide 28 by 4.

= 13 + 7

Finally, add.

= 20

Answer: D) 20

3)

The sum of the measures of the angles of a triangle is 180°.

Let the unknown angle have measure x.

x + 41° + 123° = 180°

x + 164° = 180°

x = 16°

Answer:

A) 16°

Answer:

do 8 times the number of days there is in 3 years add 365+365+365 and times that number by 8

Step-by-step explanation:

none

In 3 years Audra's account will be Deducted by $288.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

In one month the amount deducted = $8.

In 3 years there are

= 12 x 3

= 36 months.

So, In 36 month the Deduction would be

= 36 x 8

= $288.

Answer:

59.5

Step-by-step explanation:

Fig = square + triangle

Area of square =  s x s = 7^2 = 49 sq.cm

Area of triangle = 1/2 bh = 1/2 x 3 x 7 = 10.5 sq.cm

Area of fig = area of sq + area of triangle =  49 + 10.5 = 59.5 cm^2

I hope im right!!

Answer:

[tex]P(X = 0) = 0.9891[/tex]

Step-by-step explanation:

Given

[tex]\lambda = 0.011[/tex]

Required [This completes the question]

The probability of exactly 0 deaths

This probability follows a Poisson distribution, and it is given by:

[tex]P(X = x) = \frac{e^{-\lambda}\lambda^{x}}{x!}[/tex]

For 0 deaths;

[tex]x = 0[/tex]

So, the expression becomes

[tex]P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{0!}[/tex]

[tex]P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{1}[/tex]

[tex]P(X = 0) = \frac{e^{-\lambda}*1}{1}[/tex]

[tex]P(X = 0) = e^{-\lambda}[/tex]

Substitute 0.011 for [tex]\lambda[/tex]

[tex]P(X = 0) = e^{-0.011}[/tex]

[tex]P(X = 0) = 0.9891[/tex]

The probability of having exactly death is 0.9891
