You can think of x && y || z as equivalent to: int func (int x, int y, int z) { if (x) { if (y) { return true; } } if (z) { return true; } return false; } Since both x and y are fixed to be non-zero values the first return statement is always hit. thats what i think

The commercial for the new Meat Man Barbecue claims that it takes 10 minutes for assembly. A consumer advocate thinks that the c
Andrews [41]

Answer:

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes (P-value=0.009).

Step-by-step explanation:

We have to perform an hypothesis test on the mean.

The null and alternative hypothesis are:

H_0: \mu=10\\\\H_1: \mu \neq 10

The significance level is \alpha=0.05.

The test statistic t can be calculated as:

t=\frac{M-\mu}{s/\sqrt{N} } =\frac{11.2-10}{3.1/\sqrt{50} }=2.737

The degrees of freedom are:

df=N-1=50-1=49

The P-value (two-tailed test) for t=2.737 and df=49 is P=0.00862.

This P-value (0.009) is smaller than the significance level, so the effect is significant. The null hypothesis is rejected.

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes.

Complete the steps to solve the equation. 9 – 4x = 2x 1. Addition property of equality: 9 = 6x 2. Division property of equality:
exis [7]

x = 3/2

Step-by-step explanation:

Given equation is:

9 - 4x = 2x

As we have to solve for x, x will be isolated on one side of the equation

So,

<u>1. Addition property of equality </u>

4x will be added on both sides

9-4x+4x=2x+4x\\9 = 6x

<u>2. Division property of Equality</u>

Dividing both sides by 6

\frac{6x}{6}=\frac{9}{6}\\x = \frac{3}{2}

Hence,

x = 3/2

Mike hiked to a lake in 4.5 hours at an average rate of 4 1/5 miles per hour. Pedro hiked the same distance at a rate of 4 3/5 m
ExtremeBDS [4]

Answer:

distance = rate x time

3 and 1/5 = 3.2 and 3 and 3/5 = 3.6

distance = 3.2 x 4.5 = 14.4

14.4 = 3.6 x T

T = 14.4 / 3.6 = 4 <--- Pedro's time
