First, change all of your percentages to decimal points. Now we have 0.08, 0.17, and 0.75.
Now, take 40 and divide it by 0.08. You get 500, so 500 students were surveyed. 8% of 500 is 40.
Now take 500 and multiply it by 0.17 and you get 85. 85 students drive.
Take 500 and multiply it by 0.75 and you get 375, so 375 students take the bus.
You can write your fractions using the number that walked, drove, or took the bus over the amount surveyed.
The confidence interval formula is extremely complicated to derive, which is one of the justifications for using the bootstrap approach. this statement is true.
<h2>What purposes serve the bootstrap method?</h2>
A resampling technology named the bootstrap can be used to sample a dataset using replacement to calculate statistics on a group. Estimating summary statistics like the mean or standard deviation may be done using it.
<h3>The advantages of the bootstrap method</h3>
The benefits of bootstrapping include its simplicity in estimating standard errors and confidence intervals as well as its cost-effectiveness in avoiding the need to conduct the operation to get additional groups of sampled data.
Therefore it can be concluded that the said query statement is true.

#SPJ4
Density is mass (g) over volume (mL) if the 83 is in mL then
4.5 kg converted to g = 4500
4500 / 83 = 54.2 g/mL
Answer:
y=0,y=7/5,y=-9/4
Step-by-step explanation:
12y(5y-7)(4y+9)=0
Using the zero product property
12y =0 (5y-7) =0 (4y+9)=0
12y/12 =0/12 5y-7 +7 =0+7 4y+9-9=0-9
y =0 5y = 7 4y = -9
5y/5 = 7/5 4y/4 =-9/4
y = 7/5 y =-9/4
Answer:
The degree of the polynomial is equal to 7.
Step-by-step explanation:
The given polynomial is :
7x⁴– 25x + 3x⁷
We need to find the degree of the polynomial.
We know that,
Degree of the polynomial = The highest sum of exponents for anyone monomial.
In this case, the powers of x are 4,1 and 7.
Out of these three, the exponent of x is 7 which is highest.
Hence, the degree of the polynomial is equal to 7.
