GREYUIT [131]

Answer:

$2948 and $4030

Step-by-step explanation:

The CI is sample mean +/- s/sqrt(n)

t(0.95,df=63 critical values are |t|>1.669

90% CI is 3489+/-1.669*(2595/8) since sqrt(64)=8

the interval is 541.38

round to 541

the interval is 3489+/-541

($2948,$4030) is the 90% CI for the mean.

Trisha runs 3 miles every 50 minutes. At this rate, how many minutes did Trisha run in 12 miles?
SVEN [57.7K]

Answer:

200 minutes ; 3 hours and 20 minutes.

Step-by-step explanation:

If you write a proportion in the form

miles/minutes = miles/minutes

you would get 3/50 = 12/x

from there you cross multiply to get

3x=600, and solve that to get 200 minutes.


another way was to see that 12 is 3*4, and multiply 50 by 4 to get the same answer.

kotegsom [21]

The bag will often contain all three items every 70 bags ⇒ answer C

Step-by-step explanation:

At a display booth at an amusement park, every visitor gets a gift bag

according to these information:

1. Hat Every 2nd visitor

2. T-shirt Every 7th visitor

3. Backpack Every 10th visitor

We need to know how often a bag will contain all three items

To solve this problem you must find a number divisible by 2, 7, and 10

To find that number start with the multiples of the largest one and

check them with the other two numbers

∵ The largest number is 10

∵ The multiples of 10 are 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , .......

- Look for the first multiple of 10 is divisible by 7

∵ 70 is the first multiple of 10 divisible by 7

∵ 70 is divisible by 2 because its even number

∴ 70 is the smallest number divisible by 2, 7 and 10

The bag will often contain all three items every 70 bags
