Lynna [10]

Answer:False

Step-by-step explanation:

5^2+13^2=14^2

25 +169=196

194 ≠ 196

They’re not equal meaning it’s not a right triangle. Sorry for my first answer. I was supposed to use the Pythagorean theorm

The equation y = 43x represents the number of miles Alicia drives over time, where y is the number of miles and x is time in hou

spin [16.1K]

Alicia : y = 43 x
For x = 1 ( 1 hour ):
y = 43 miles, v = 43 mph
Trish: 69 = v * 1.5
v = 69 : 1.5
v = 46 mph
Alicia: 43 mph
Trish: 46 mph
The woman who drives at a slower rate is : A ( Alicia )

Use the information from the polling agency to determine the sample size needed to construct a 95% confidence interval with a ma

Ber [7]

Answer:

the sample size n= 771

sample proportion is p = 1/2

Step-by-step explanation:

Step1:-

marginal error formula is $\frac{2S.D}{\sqrt{n} }$

but if 'n' is sample size then $n = \frac{1}{(margin error)^{2} }$

Given margin error is 36% = 0.036

$n= \frac{1}{(0.036)^2}$

on simplification , we get n= 777 polling agencies

Step 2:-

$Margin of error = \frac{2\sqrt{p(1-p)} }{\sqrt{n} }$

substitute values , we get

$\frac{36}{100} = \frac{2\sqrt{p(1-p)} }{\sqrt{771} }$

after simplification, we get

$\sqrt{p(1-p)} = \frac{1}{2}$

squaring on both sides, we get

$p(1-p) = \frac{1}{4}$

multiply 'p' inside

$p-p^{2} =\frac{1}{4}$

cross multiplication '4' and simplify

$4p^{2} -4p +1 =0$ ........(1)

finding 'p' value

The equation (1) is of the form $(a-b)^{2} = a^{2} -2ab+b^{2}$

$(2p)^{2} -2(2p)(1)+1^{2} = (2p-1)^2$

$(2p-1)^2 =0$

$p=\frac{1}{2}$

conclusion:-

The sample size is 771

the sample proportion is p = $\frac{1}{2}$

a season ticket for bolton f.c. this season cost £410 it is to go up by 34% next season how.much will a season ticket cost next

OleMash [197]

This should be right if you're doing multipliers -

100 + 34 = 134
÷ 100 = 1.34
1.34 is your multiplier. So if you do 410 x 1.34 you'll have £549.40
I may be wrong, but I'm quite sure this is right!
