Step-by-step explanation:

To find average you must add up all of the numbers and then divide by the amount of numbers there are

2+3+6+5= 16

there are 4 numbers, so you do 16/4

16/4 = 4

Answer:

x=4 z=117

Step-by-step explanation:

Answer:

x = 4, z = 117

Step-by-step explanation:

14x + 7 and 63 are vertically opposite angles and are congruent, then

14x + 7 = 63 ( subtract 7 from both sides )

14x = 56 ( divide both sides by 14 )

x = 4

z and 63 are adjacent angles and are supplementary, then

z + 63 =180 ( subtract 63 from both sides )

z = 117

Answer:

[tex]\theta=41.18^{\circ}[/tex]

Step-by-step explanation:

Given that,

The height of the tree, h = 14 ft

The height of the shadow, b = 16 ft

We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,

[tex]\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{14}{16}\\\\\theta=41.18^{\circ}[/tex]

So, the required angle of elevation of the sun is equal to [tex]41.18^{\circ}[/tex].

Answer:

0.55 ; 0.32 ; 0.7

Step-by-step explanation:

Let :

Spanish = S ; French = F ; German = G

SnFnG = 3

(SnF) only = 9 - 3 = 6

(SnG) only = 5 - 3 = 2

(FnG) only = 5 - 3 = 2

S only = 28 - (6+3+2) = 17

F only = 21 - (2+3+2) = 14

G only = 12 - (6+3+2) = 1

Student not taking any of the classes :

(100 - (17+14+1+2+2+6+3))

100 - 45 = 55

A.) P(not taking any language class).

Required outcome = 55

Total possible outcomes = 100

= 55 / 100 = 0.55

B.)

P(taking exactly one language class)

(S only + F only + G only) / 100

(17 + 14 + 1) / 100

= 32/100

= 0.32

C.)

Atleast 1 is taking a language class out of 2 selected

Possibilities :

(taking and not taking) ;

(not taking and taking) ;

(taking and taking)

(45/100 * 55/99) + (55/100 * 45/99) + (45/100 * 44/99) = 0.7

Answer:

See Below.

Step-by-step explanation:

We have the expression:

[tex]5^5-5^4+5^3[/tex]

And we want to prove that it is divisible by 7.

To do so, we can factor out a 5³ from the expression. This yields:

[tex]=5^3(5^2-5^1+1)[/tex]

Simplify the parentheses:

[tex]=5^3(25-5+1)=5^3(21)[/tex]

We can see that the resulting expression is a value being multiplied by 21.

Since 21 is divisible by 7, our original expression must also be divisible by 7.

Hence proven.

Answer:

3x - 4y = -4

Step-by-step explanation:

When you put co-ordinate in it then give zero

3(-4)-4(-2)+3=0

3x-4y=-4   equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given equation is 3x - 4y = 7

Convert it to slope intercept form

-4y = 7 - 3x

4y=-7+3x

y=-7/4+3/4x

y=3/4x-7/4

3/4 is the slope and the parallel line should also have the same slope.

Now equation of line passing through (-4, -2)

-2=3/4(-4)+b

-2=-3+b

-1=b

So y=3/4x-1

3x-4y=-4 is another equation represents the line which is parallel.

Hence, 3x-4y=-4   equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).

Answer:

369

Step-by-step explanation:

The researchers need a sample size of 385 to estimate the proportion of adults who would say they learned something new in the past month with a 95% confidence level and a margin of error of no more than ±5%.

The margin of error is the amount of error or uncertainty in a statistical estimate, usually an estimate of a population parameter based on a sample.

We have,

To create a one-sample z-interval, the following steps can be followed:

Determine the sample size (n) and the sample proportion p.

Since no sample size or proportion is given in the problem, we cannot proceed with this step.

Determine the level of confidence (C) for the interval. In this case, the researchers want a confidence level of 95%, so C = 0.95.

Find the critical value (z*) for the level of confidence.

This can be done using a standard normal distribution table or a calculator.

For a 95% confidence level, the critical value is 1.96.

Calculate the margin of error (ME) using the formula:

ME = z x √(p x (1 - p) / n)

Since the margin of error is given as no more than ±5%, we can set it equal to 0.05 and solve for the required sample size:

0.05 = 1.96 x √(0.4 x (1 - 0.4) / n)

Solving for n, we get:

n = (1.96 / 0.05)² x 0.4 x (1 - 0.4)

n ≈ 384.16

Since the sample size must be a whole number, we round up to the nearest integer and get n = 385.

Therefore,

The researchers need a sample size of 385 to estimate the proportion of adults who would say they learned something new in the past month with a 95% confidence level and a margin of error of no more than ±5%.
