At the factory a baseball card is places in every 9th cereal package a football card is placed in every 25th package what is the
strojnjashka [21]
To figure out this question, look for the first number where both 25 and 9 are a factor of. 

25*1 is 25 which isn't a factor of 9, so it won't be 25.
25*2 is 50, which isn't a factor of 9.
75 is not a factor of 9. (you know because you don't get a whole number when you divide 75 into 9.)
100 is not a factor of 9, nor is 125, 150, 175, or 200.

However, 225 is a factor of both 25 and 9. This makes sense because 25*9 is 225. 

This means that the first package with both will be the 225th package.

marshall27 [118]

Answer:

The answer is in the explanation

Step-by-step explanation:

Mean value = \bar x = 438

(a) The data appeared to be centered towards 438.

There are little or no skew.

There is no outliers.

(b) yes

(c) standard deviation = s = 14.8955

95% confidence interval = +- t_{df}  * s\sqrt{n}

    438 +- 2.12 * 14.8955 /\sqrt{17}=

= (430.3415, 445.6585)

(d) Test statistic

t = (438 - 450)/{14.8955\sqrt17} }

t = -3.3216

p -value is correctly given in option b.

No, 450 is not a plausible valaue.

For how many weeks would the class need to have car washes to earn $5000.
nikdorinn [45]
The correct answer would be for 29 weeks.
Its because if for 4 weeks the profit is $700, divide 700 and 4 which gives you $175 per week. Then divide 5000 and 175 which gives you 28.5714286. So all you have to do is round it up to the nearest whole which gives you the answer: 29 weeks.
Hope that helps. :)
