What is the equation of the horizontal asymptote? f(x)=4(52)x+7<br> y=?

natta225 [31]

ANSWER

y=7

EXPLANATION

The horizontal asymptote of an exponential function

$f(x)= a {(b)}^{x} + c$

is y=c.

The given exponential function is

$f(x)= 4 {(52)}^{x} + 7$

When we compare to

$f(x)= a {(b)}^{x} + c$

c=7, therefore the horizontal asymptote is y=7.

Suppose that in a random selection of 100 colored candies, 26% of them are blue. The candy company claims that the percentage

quester [9]

Answer: a) -0.2252, b) 0.8219

Step-by-step explanation:

Since we have given that

Sample size n = 100

Probability that candies are blue = p= 0.26

Probability that company claims that it is blue candy = P = 0.27

So, Q = 1-P= 1-0.27 = 0.73

So, Null hypothesis : $H_0:p=P$

Alternate hypothesis : $H_1:p\neq P$

So, the test statistic would be

$z=\dfrac{p-P}{\sqrt{\dfrac{P.Q}{n}}}\\\\z=\dfrac{0.26-0.27}{\sqrt{\dfrac{0.27\times 0.73}{100}}}\\\\z=-0.2252$

Since α = 0.05

So, critical value of z = 1.96

p-value = P(Z>Z(calculated)

Using the excel function , we get that

$P(z>0.2252)\\\\=2\times 0.410.911845\\\\=0.8219$

Hence, a) -0.2252, b) 0.8219

Can some one really help me please!!!! :(((

GREYUIT [131]

Answer:

for the first on its a=24 and for the second its a= 48

Step-by-step explanation:

for the first one you have to find the length which is 8 and then you find the width which is 3 then you multiply that to get 24

for the second one you find the base which is the strait line which is 8 then you find the height which is 6 then you multiply it to get 48 i hopes this helped!

Is 4 to 7 the same as 7 to 4? Explain why or why not.

Julli [10]

Yes because 4 to 7 is the same as 7 x 4 which equals 28. 7 to 4 is the same as 7 x 4 which also equals 28.
