Answer:

63/10 : 9/2

Step-by-step explanation:

6.3 is 6 and 3/10

we can turn that into an improper fraction so its 63/10

4.5 is 4 and 1/2

we can turn this into an improper fraction with is 9/2

so now its 63/10 : 9/2 as a ratio

Hope this helps. Good luck.

v =  \frac{1}{3} \pi {r}^{2} h \\ r = 8 \: cm \\ h = 15 \: cm
From the diagram, we can see that the radius of the cone is 8cm and the height of the cone is 15cm. We then just plug these numbers into the formula and simplify:
v =  \frac{1}{3} \pi {r}^{2} h \\ v =  \frac{1}{3} \pi {(8)}^{2} (15) \\ v = 320\pi
The volume of the cone is approximately 1005.3096 cm^3. With 3 sig figs, this is 1010 cm^3.

In triangle abc, AC=15 BC=11 and m
Oksana_A [137]

Answer: 10

Step-by-step explanation:

In a right angle triangle

Hypothenus ^2= opposite ^2+ adjacent ^2

According to a diagram below

Hypothenus =15

Opposite =?

Adjacent =11

Substitute for the values

15^2=11^2+opp^2

Opp^2=15^2-11^2

0pp^2= 225-121

Opp2=104

Opp= square root of 104

Opp= 10.2

Opp= ~10

You collect a random sample of size n from a population and calculate a 90% confidence interval. Which of the following strategi
Daniel [21]

Answer:

Decrease the sample size.

Step-by-step explanation:

Margin of error is:

ME = CV × √(σ / n)

where σ is the population standard deviation, or:

ME = CV × √(p (1 − p) / n)

where p is the proportion.

In each case, the margin of error is directly proportional to the critical value, and inversely proportional to √n.

Lowering the confidence level will lower the critical value, which will decrease the margin of error.  Decreasing the sample size will increase the margin of error.

Need help getting stuck on this problem
stepan [7]

Answer:

  • Variable x in first equation

Step-by-step explanation:

<u>Given system</u>

  • x = 5y - 1
  • x + 2y = 13

Variables in this system are x and y.

Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.

We see <u>variable x is isolated </u>in the first equation.

In the second equation both of the variables are on the same side so they are not isolated.
