Despite the other answer, this looks like exponentiation.

The parentheses are necessary; without them

4^{3^5}=4^{(3^5)}

which happens to be 147 digits long.

We're asked

(4^3)^5

Parenthesized this way we can multiply the exponents

(4^3)^5 = 4^{15}=(2^2)^{15}=2^{30}

Two to the thirtieth is 1,073,741,824, about a billion. But that's not really that helpful for understanding what's going on so let's leave it as a power of two.

Answer: 2^{30}

F(x) = |2x + 1| + 3
worty [1.4K]

Answer:

(f + g)(x) = I2x + 1I + 1 ⇒ C

Step-by-step explanation:

Let us solve the question

∵ f(x) = I2x + 1I + 3

∵ g(x) = -2

→ We need to find (f + g)(x), which means add the two functions

∵ (f + g)(x) = f(x) + g(x)

→ Substitute the right side of each function on the right side

∴ (f + g)(x) = I2x + 1I + 3 + (-2)

→ Remember (+)(-) = (-)

∴ (f + g)(x) = I2x + 1I + 3 - 2

→ Add the like terms in the right side

∵ (f + g)(x) = I2x + 1I + (3 - 2)

∴ (f + g)(x) = I2x + 1I + 1

100 POINTS!!!!!!!!
yawa3891 [41]

Form the confidence level (99%), we calculate the "alpha" value

alpha=1-(99/100)=0.01

Now, calculate the critical probability (p-start)

p*=1-(alpha/2)=1-(0.01/2)=0.995

z-score could be calculated from p*,,,

z-score=2.57583

Now, calculate the Margin of Error:

standard deviation = s

number of adults = n

ME=(z*s)/(sqrt n)=(2.57583*12)/(sqrt 250) = 1.955

The confidence interval = mean +or- ME

                                     = 70+1.955  or  70-1.955

So that we can conclude that the 99% confidence interval for the mean beats per minute is 68.045 and 71.955

I hope you got the idea!
