Answer:
Step-by-step explanation:
Information provided
n=100 represent the random sample taken
X=21 represent the number of bags overfilled
estimated proportion of overfilled bags
is the value that we want to test
z would represent the statistic
Hypothesis
We need to conduct a hypothesis in order to test if the true proportion of overfilled bags is higher than 0.15.:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is:
(1)
And replacing the info given we got:
Answer:
-62
Step-by-step explanation:
-2 + (6)(-10) = -2 -60 = -62
__
2 less than a product is 2 subtracted from the product, or -2 added to the product. A product is formed by multiplying the given numbers.
The product of 6 and -10 is 6×(-10) = -60. 2 less than that is -62.
The equation represents two equivalent expressions [ similar sides ]
Hope this helps!
Answer:
Step-by-step explanation:
Given that:
Jillian is willing to trade her wool cards for David ore cards
The double number line indicates that:
David will trade three ore cards to Jillian for six wool cards;
Based on the ratio, we have:
= 2
Thus, the number of wool Jillian would need to trade for 1 ore card will be
= 1 × 2
= 2
For 2 ore card
= 2 × 2
= 4
For 3 ore card
= 3 × 2
= 6
The number of wool Jillian would need to trade for 4 ore card will be
= 4 × 2
= 8
1. It's a rational number as it's written in fraction form.
2. It's a repeating because if you divide 62/495 you get 12.5252...(52 repeating)
