Answer:

Step-by-step explanation:

1. Replace n with 10. The equation will look like:

-5+9(10-1)

2. Remember PEMDAS! The first step in solving the equation is solving whatever is in the parenthesis:

-5+9(9)

3. The next step is exponents, but since there aren't exponents in the equation, we move to multiplication and division. The equation should now look like this:

-5+81

4. Now we move on to addition and subtraction; add the two numbers!

-5+81=76

There's your answer!! Hope this helped :)

The odds against Carl beating his friend in a round of golf are 9:7. Find the probability that Carl will lose?

grandymaker [24]

The ratio 9:7 gives you following statement:

Carl will win in 9 cases from 9+7=16;
Carl will lose in 7 cases from 16.

Then the probability that Carl will lose is

$Pr(\text{Carl will lose})=\dfrac{7}{16}.$

Answer: $Pr(\text{Carl will lose})=\dfrac{7}{16}.$

4. Anna, Beate and Cindy buy a bag of 30 biscuits together. They get 10 biscuits each. But Anna has paid 80 cents, Beate 50 cent

erma4kov [3.2K]

Answer:

Option E. 6.

Step-by-step explanation:

80:50:20 or 8:5:2. 8 ÷ 15 * 30 = 16 = 16 - 10 = 6. This is the solution.

Option A. 30 + 10 = 40. Incorrect. The solution is unequal to this.
Option B. 30 + 9 = 39. Incorrect. The solution is unequal to this.
Option C. 30 + 8 = 38. Incorrect. The solution is unequal to this.
Option D. 30 + 7 = 37. Incorrect. The solution is unequal to this.
Option E. 30 + 6 = 36. Correct. The solution equals this answer.

Option E will be the answer.

Complete the statements. f(4) is f(x) = 4 when xis

inessss [21]

Think about this as a table of values where domain is the x values and range is the y values.

f(4) wants the y-value when the x-value is 4

f(4) = 1/2

The second question wants us to find the x-value when f(x) also known as the y-value is 4.

f(x) = 4

x = 8

answers: 1/2, 8
