Answer:
(i) an isosceles triangle is a triangle where two angles are equal and one is different
(ii) same as above
(iii) sorry but im not sure
(iv) a=1.41 b=11.31 c=7.07
So check the picture below
if we check the solutions or zeros for the equation, we get
and as you can see in the picture, the value of "x" when y = 3.5, or the height of the truck is
the truck, ends up with a clearance of
on either side, so, the maximum clearance, the truck can have, those two clearances added together,
Answer:
10.5625 is the answer I got.
Step-by-step explanation:
I used the process PEMDAS for this equation.
(6.5÷2)^2
6.5÷2= 3.25^2
Now you bring down the new quotient and multiply it by itself.
3.25 x 3.25= 10.5625
Answer:
$243
Step-by-step explanation:
81 x 3= 243 I'm pretty sure.
A 99% confidence interval for the population mean of high school students that take the bus to school every day is b) ci=(44.34%, 54.43%)
We need to find the 99% confidence interval for the population mean of high school students that take the bus to school everyday
A confidence interval is a range of estimates for an unknown parameter. The confidence interval is calculated at the specified confidence level; the most common is the 95% confidence level, but sometimes other levels are used, such as 90% or 99%.
The confidence interval of proportions is given by:
π ± z √(π (1-π) /n)
π is the sample proportion.
z is the critical value.
n is the sample size.
For 99% confidence interval the value of z is 2.58
π = 321/650
The confidence interval is given by
=321/650 ± 2.58 √( (321/650) × [ 1 - (321/650) ] ÷ 650)
= (0.493846 ± 0.050594)
=(0.4434 , 0.5443)
=(44.34 % , 54.43 %)
Hence a 99% confidence interval for the population mean of high school students that take the bus to school every day is ci=(44.34%, 54.43%)
