Answer:

There are 59,049 different ways of answering the exam.

Step-by-step explanation:

The first thing we need to count is the total number of selections, then we need to count the number of options for each one of these selections. The total number of combinations will be equal to the product between all the numbers of options.

Here, the selections are each one of the 10 questions, so we have 10 selections.

And each one of these selections has 3 options (true, false, blank)

So, we have 10 selections with 3 options each, then the total number of combinations will be:

C = 3*3*3*3*3*3*3*3*3*3 = 3^10

C = 59,049

There are 59,049 different ways of answering the exam.

Answer:

A

Step-by-step explanation:

In 2 months, he got 70 stamps, meaning 35 stamps per month. On the first month, he has 55 stamps by the end of the first month, and since every month he gets 35 stamps, He was given 20 Stamps to start with. It is not D since he saves 35 stamps himself every month, meaning from the beggining of that month, he had 20, and by the end had 55, since the question specifies it shows the amont of stamps at the END of the month.

Answer:

6

Step-by-step explanation:

We need to solve the equation .The given equation is ,

→ 8 - 6x = -28

→ -6x = -28-8

→ -6x = -36

→ x = -36/-6

→ x = 6

Answer:

[tex]y=-\frac{2}{3}x[/tex]

Step-by-step explanation:

Equation: y=mx+b

we know the slope (m) and so we can write

(-2/3)x+b=y

we need to solve for b

to do this plug in 6 for x and -4 for y

(-2/3)(6)+b= -4

-4+b= -4

b=0

therefore the final answer is just

(-2/3)x

Answer: 30 fish

Step-by-step explanation:

A tank measuring 5 feet by 3 feet by 3 feet has a volume of 5*3*3 =45 cubic feet.

If there are 45 cubic feet of water in this tank, and each fish requires 1.5 cubic feet of water, the number of fish that can fit in the tank is 45/1.5 = 30.

Answer:

The slope of the line is 4.

Step-by-step explanation:

Recall that slope = rise over run:  rise / run.

From the table we see that if x changes from 0 to 4, a run of 4, y changes from -1 to 15, a rise of 16, the slope of this line must be

m = rise / run = 16/4 = 4

The slope of the line is 4.

Answer:7.85

Step-by-step explanation:

7 17/20 as a decimal is 7.85

how I got that?

1. 17/20=0.85

2, 7+0.85=7.85

hope this helps!

Answer:

-50 N

Step-by-step explanation:

125 - 75 = 50

left = negative

right = positive

The ball is going to be kicked to the left because the net force on the right is larger, and as you can see above, left = negative and right = positive. So the answer would be -50 N

The solution is: When the line passes through x = -6, the value of y is: -13.

Here, we have,

given that,

A line on a coordinate plane passes through the point (2, -7) and has a slope of 0.75.

we know the equation of straight line is: ;

y = mx + c

here, m = 0.75 and, (x,y) =(2, -7)

so, we get,

c = -7 - 0.75*2 = - 8.5

So, the equation of straight line is:

y = 0.75x - 8.5

now, when the line passes through x = -6,

we get,

y =  0.75* (-6) - 8.5

  = - 13

Hence, The solution is: When the line passes through x = -6, the value of y is: -13.

Answer:

it in a is correct if im wrong it is B

Step-by-step explanation:

==================================================

Explanation:

From the given info, we see that 91 is two standard deviations above the mean. The diagram shows 91 is two tickmarks to the right of center. Or we could note that z = (x-mu)/sigma = (91-75)/8 = 2.

Roughly 95% of the normal distribution is within 2 standard deviations of the mean. I'm using the Empirical Rule.

So about 95% of the population is between 59 and 91 inches tall. That leaves 5% of the population in both tails combined. Cut this in half to get 2.5%

We have 2.5% of the population taller than 91 inches

2.5% of 4500 = 0.025*4500 = 112.5 = 113

Roughly 113 people are taller than 91 inches

Answer:

non-negative

Step-by-step explanation:

Given

[tex]-4x\cdot y\cdot 0^6[/tex]

[tex]x , y > 0[/tex] --- Positive numbers

Required

The sign

[tex]-4x\cdot y\cdot 0^6[/tex]

First, we simplify the expression

[tex]0^6 = 0[/tex]

So:

[tex]-4x\cdot y\cdot 0^6 = -4x\cdot y\cdot 0[/tex]

The product of 0 and any factor is 0. So:

[tex]-4x\cdot y\cdot 0^6 = 0[/tex]

Since the result is 0, then the sign is non-negative

Answer:

Commutative property

Step-by-step explanation:

Commutative property is usually 2 equations switched around

Answer:

g(x) = 5ln (x-6)

Step-by-step explanation:

For us to have a vertical stretch, we need to multiply the whole function by the factor of stretching

Say for example, we stretched f(x) by a factor of a , we have the result as a•f(x)

Now, when we shift by a certain number of units, this is particularly a translation

The kind we have here is a horizontal translation

So by shifting 6 units left, we have it that we need to subtract 6 units from the x-coordinate value

Thus, we have the resulting function as;

g(x) = 5ln (x-6)

Answer:

La medida del tercer ángulo interno es 85°.

Step-by-step explanation:

Los triángulos son figuras geométricas planas que poseen tres lados en contacto entre sí en puntos comunes denominados vértices. A su vez, los triángulos poseen tres ángulos interiores. Estos tres ángulos interiores del triángulo suman 180°.

En este caso, en un triángulo, dos de sus ángulos internos miden 40º y 55º. Siendo θ el tercer ángulo interior, entonces:

θ + 40° + 55°= 180°

Resolviendo:

θ + 95°= 180°

θ= 180° - 95°

θ=85°

La medida del tercer ángulo interno es 85°.
