Answer:
The garden can not have area of 700ft^2
Step-by-step explanation:
We are given equation for area as
where
w is the width (in feet) of the garden
now, we are given area =700 ft^2
so, we can set area =700
and then we can solve for w
now, we can use quadratic formula
we can compare and find a,b, and c
a=-1 , b=50 , c=-700
now, we can plug values
We can see that values of w is not real
so, w does not exists when area =700
so, The garden can not have area of 700ft^2
Sample space ={13 H + 13 D + 13 S + 13 C} = 52 cards
P(getting one heart) = 13/52 = 1/4
P( getting NO heart) = 1-1/4 = 3/4 = 0.75

Answer:
a. There's a 95% chance that the true proportion is in the confidence interval.
Step-by-step explanation:
When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.
Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.
When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.
The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
