AC and DB are the same length. Set the two to equal each other and solve for y.

9y + 1 = 8y +17

Subtract 8y from both sides:

y + 1 = 17

Subtract 1 from each side:

y = 16

Now you know Y you can find the the length of DB:

DB = 8y +17 = 8(16) +17 = 128 + 17 = 145

EB is half of DB:

EB = 145 / 2

EB = 72.5

When fritz drives to work his trip takes 30 ​minutes, but when he takes the train it takes 20 minutes. find the distance fritz
Naddika [18.5K]
Let n be Fritzs' car speed, and n+12 be the speed of the train. Then:
1/2 (n)=1/3 (n+12)
2n+24=3n
n=24 mph
n+12=36 mph
Fritz travels 12 miles to work.
30 min @24mph=12 miles
20 min @36mph=12 miles

Will records the wins and losses for his high school basketball team each year. He notices that the ratio of wins to losses has
AleksAgata [21]

Answer: 3

<u>Step-by-step explanation:</u>

 <u>Wins</u>      <u>Losses</u>            <u>Pattern</u>

   18             2               18 ÷ 2 = 9

   45            5               45 ÷ 5 = 9

   36            4               36 ÷ 4 = 9

   27            x

Using the same pattern we have  

  27 ÷ x = 9    

→        x = 3

Suppose that x is a Normally distributed random variable with an unknown mean μ and known standard deviation 6. If we take repea
nata0808 [166]

Answer:

1.2

Step-by-step explanation:

Given that X is Normally distributed random variable with an unknown mean μ and known standard deviation 6

Hence we can say for a sample of size 100, the sample mean will have a std deviation of = \frac{6}{\sqrt{100} } =0.6

Since population std deviation is known we can use Z critical value for finding out the confidence interval

For 95% using (68-95-99.7 rules) we have z critical value =2

Hence margin of error =2(std error) = 1.2

Confidence interval 95%

Lower bound = Mean - margin of error = Mean -1.2

UPper bound = Mean +1.2

Hence , 95% of all of these values of x should lie within a distance of __1.2___ from μ .

A recipe calls for chocolate chips in a ratio of 1 cup of white chocolate chips to 2 cups of milk chocolate chips. How many milk
emmasim [6.3K]

Answer:

4 cups of milk chocolate

Step-by-step explanation:

if there are 6 cups in total, then you can see that 1:2 is equal to 3 cups in total. If you multiply both sides of the ratio by 2, then you get 2:4, which is 6. You have to add the chocolate together to find how much it equals in total. Because it's white chocolate to milk chocolate, that would be 2:4, so there are 4 cups of milk chocolate.
