Ania scored a total of 120 points this season so far and averaged 15 points a game. How many games has she played?

arlik [135]

She played 8 games. Since she earned a total of 120 points and 15 points per game you would divide 120/15=8

Help please (question is kinda easy and its timed so i need help asap)

AveGali [126]

Option 1: $y = 5x+5$ is the correct answer

Step-by-step explanation:

We can put the values of x in each option one by one and then compare the output to find the best option

So,

Putting x=1,2,3,4,5...

$y = 5(0)+5 = 0+5 = 5\\y = 5(1) +5 = 5+5 = 10\\y = 5(2) + 5 = 10+5 = 15\\y = 5(3) + 5 = 15+5 = 20$

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5

Hence,

Option 1: $y = 5x+5$ is the correct answer

The cost of a layer cake is $17 plus $5 per layer. If Paul has only $30 to spend on a cake, what is the most number of layers he

VikaD [51]

Answer:

The most number of layers he can afford is 2

Step-by-step explanation:

We automatically have a fee of 17 so we know we have 13 dollars remaining. Using this information, we know that one layer is 5 dollars which means we can get 2 layers which is equal to 10 dollars which turns our total fee to $27. Hope this helps!

Past experience has indicated that the breaking strength of yarn used in manufacturing drapery material is normally distributed

vlabodo [156]

Answer:

95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm)

Step-by-step explanation:

Our sample size is 11.

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

$df = 11-1 = 10$ .

Then, we need to subtract one by the confidence level $\alpha$ and divide by 2. So:

$\frac{1-0.95}{2} = \frac{0.05}{2} = 0.025$

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 10 and 0.025 in the two-sided t-distribution table, we have $T = 1.812$

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

$s = \frac{4}{\sqrt{11}} = 1.2060$

Now, we multiply T and s

$M = Ts = 1.812*1.2060 = 2.19/tex]For the lower end of the interval, we subtract the sample mean by M. So the lower end of the interval here is[tex]L = 97 - 2.19 = 94.81 = 94.8$ cm

For the upper end of the interval, we add the sample mean and M. So the upper end of the interval here is

$L = 97 + 2.19 = 99.19 = 99.2$ cm

95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm).
