3 ratios equivalent to 18:14

1 answer:

8 0

Think of it this way...ratios can be written as fractions...so 18:14 can be written as 18/14...so basically, ur equivalent ratio is just finding equivalent fractions.
18/14 is equivalent to 9/7, 36/28, and 54/42...so 3 equivalent ratios are :
9:7 , 36:28, 54:42.

Answer: B

Explanation

When rolling a dice, no matter how many times you get an outcome, it can never determine the exact outcome of the next roll, hence it is termed an independent event.

Hope this helps :)

In-s [12.5K]

Answer:

6:41

Step-by-step explanation:

We know that the number of students going on the field trip is 6.

To find the total number of students, add the number of students going on the trip and the number of students staying at the school: 6 + 35 = 41

So the ratio of the number of students going on the field trip to the total number of students is 6:41

Lifetimes of AAA batteries are approximately normally distributed. A manufacturer wants to estimate the standard deviation of th

AURORKA [14]

Answer:

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.

(8.889, 11.7106)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 23

Mean of the sample x⁻ = 10.3

Standard deviation of the sample (s) = 2.4

Level of significance = 0.05

Degrees of freedom = n-1 = 23-1 =22

Step(ii):-

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.

$(x^{-} - t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} } , x^{-} +t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} } )$

$(10.3 - t_{\frac{0.05}{2} } \frac{2.4}{\sqrt{23} } , 10.3 +t_{\frac{0.05}{2} } \frac{2.4}{\sqrt{23} } )$

(10.3 - 2.8188 (0.50043) , 10.3 + 2.8188(0.50043)

(10.3-1.4106 , 10.3+1.4106)

(8.889, 11.7106)

final answer:-

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.
