Sam said that 105 is 50 because 10 + 10 + 10 + 10 + 10 = 50. Is Sam correct? Explain.
Select the correct answer below and, if necessary, fill in the answer box to complete your choice.

Answers

Answer:

He is wrong

Step-by-step explanation:

105≠ 50

10+10+10+10=50

5(10)= 50

To get 105 you would have to add 10 ten times and then add 5. Adding ten five times will only give you are value of 50.

Given 45-45-90 triangle with hypotenuse of 3cm solve for the other sides.

Answers

Answer:

[tex]\sqrt{\frac{9}{2} }[/tex]

Step-by-step explanation:

Given dimensions:

The right angle system is a 45 - 45 - 90

Hypotenuse = 3cm

Unknown:

Adjacent and opposite sides = ?

Solution:

In this triangle, the adjacent and opposite sides are equal to one another. So,

Let adjacent = y

opposite = y

For right angle triangles as this, using the Pythagoras theorem,

hypotenuse² = adjacent² + opposite²

Insert the parameters and solve;

3² = y² + y²

2y² = 9

y² = [tex]\frac{9}{2}[/tex]

y = [tex]\sqrt{\frac{9}{2} }[/tex]

Write the quadratic equation whose roots are −6 and 4, and whose leading coefficient is 4. (Use the letter x to represent the variable.)

Answers

Answer:

4(x-4)(x+6)

Standard form: 4x^2+8x-96

Step-by-step explanation:

Since the roots are set to be -6 and 4, we need to find 2 linear equations that are equal to 0 when x is at -6 and when x is at 4, and multiply them together. That would look like this:

(x-4)(x+6)

Notice how if I plug in 4 or -6 for x, the whole thing is going to be 0.

Now, if we were to factor this, the leading coefficient would be 1. Since we want to change the leading coefficient while still preserving our roots, we can just multiply the whole polynomial by 4:

4(x-4)(x+6)

Notice if I still plug in 4 or -6 for x, the whole thing is going to be 0.

In standard form, the polynomial would be 4x^2+8x-96.

if you flip three coins, the probability of getting three heads is 1/8. Interpret this probability.

Answers

Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. So the probability that it lands heads up, then tails up, then heads up is 1/8, or 12.5%.
(Also you can use the formula for that.

The interpretation of the probability is there is a 12.5% chance of obtaining three heads when three coins are flipped

The probability is given as:

[tex]\mathbf{Pr = \frac 18}[/tex]

The above represents the probability of flipping a head three times.

Express as decimal

[tex]\mathbf{Pr = 0.125}[/tex]

Express as percentage

[tex]\mathbf{Pr = 12.5\%}[/tex]

This means that, there is a 12.5% chance of obtaining three heads when three coins are flipped

-66 = -9n + 16n + 4
Solve these step by step pls

Answers

Answer:

n= -10

Step-by-step explanation:

-66=7n+4

-7n=4+66

-7n=70

n=70/-7

n= -10

Answer:

n = -10

Step-by-step explanation:

-66 = -9n + 16n + 4

1. I started by subtracting 4 on both sides of the equation this gives you -70 = -9n + 16n

2. I then combined the like terms 16n and -9n on the right side of the equation. We do this by subtracting 9n from 16n. Which gives you -70 = 7n

3. We then divide both sides by 7 in order to get -10 = n

This gives you your final answer of n = -10
