Answer:
5 points
Step-by-step explanation:
Alice, Bianca, Camila, and Dasha each scored 14 points. 14 x 4 = 56
56 + 15 = 71
3 x 5 = 15
The three remaining girls scored 5 points each.
Answer:
4D - 1
Step-by-step explanation:
So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.
Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.
Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.
Answer:
0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 17.39 ppm
Standard Deviation, σ = 4.25 ppm
Sample size = 11
We are given that the distribution of printing speed is a bell shaped distribution that is a normal distribution.
Formula:
P(printing speed of the sample is greater than 17.99 ppm.)
P(x > 17.99)
Calculating the value from the standard normal table we have,
Thus, 0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
The answer is 439.
3+(1/(7+1/15) = 333/106
333+ 106 = 439.
Answer:
f = 16
Step-by-step explanation:
Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other. Multiply 8 to both sides of the equations:
2 = (f/8)
2(8) = (f/8)(8)
f = 2 * 8 = 16
f = 16 is your answer.
