Test 24,515 for divisibility by 2, 3, 5, 9, or 10.

lord [1]

Answer:

Step-by-step explanation:

1. When a number is divisible by 2 it must end with even digit 0, 2, 4, 6 or 8.

So the number 24,515 is not divisible by 2.

2. When a number is divisible by 5 it must end with digit 0, or 5.

The number 24,515 ends with 5 so it is divisible by 5.

3. When a number is divisible by 3, the sum of all digits must be divisible by 3.

The sum of all digits of the number 24,515 is 2+4+5+1+5=17. 17 is not divisible by 3, so the number 24,515 is not divisible by 3.

4. When a number is divisible by 9, the sum of all digits must be divisible by 9.

The sum of all digits of the number 24,515 is 2+4+5+1+5=17. 17 is not divisible by 9, so the number 24,515 is not divisible by 9.

5. When a number is divisible by 10 it must end with digit 0.

The number 24,515 ends with 5 so it is not divisible by 10.

Identify the parameters in the following situation. When Jackie is camping, she sees 6 shooting stars every hour, on average. Wh

andrey2020 [161]

Answer:

The probability that she sees exactly 4 shooting stars in the next hour is 0.13

Step-by-step explanation:

An assumption is made that she see the shooting stars of 6 every hour based on a poisson distribution.

$P(X = x) = \frac{e^{-m} m^{x} }{x!}$

where m is the average per hour = 6

$P(X = x) = \frac{e^{-m} m^{x} }{x!}\\P(X = 4) = \frac{e^{-6} 6^{4} }{4!}\\P(X = 4) = \frac{0.002478752 * 1296 }{4!}\\P(X = 4) = \frac{3.212462592}{24}\\P(X = 4) = 0.133852618\\P(X = 4) = 0.13$

If p varies directly as q and q= 70 when p= 10, find q when p = 12

stellarik [79]

$\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\ \textit{\underline{x} varies directly with }\underline{z^5}\qquad \qquad \stackrel{\textit{constant of variation}}{x=\stackrel{\downarrow }{k}z^5~\hfill } \\\\[-0.35em] ~\dotfill$

$\stackrel{\textit{"p" varies directly as "q"}}{p~~ = ~~kq}\qquad \textit{we also know that} \begin{cases} q=70\\ p=10 \end{cases}\implies 10=k70 \\\\\\ \cfrac{10}{70}=k\implies \cfrac{1}{7}=k\hspace{15em}\boxed{p=\cfrac{1}{7}k} \\\\\\ \textit{when p = 12, what is "q"?}\qquad 12=\cfrac{1}{7}q\implies 12=\cfrac{q}{7}\implies 84=q$

Solve 12(x - 2) + 3x = {(x + 12) + 10x

jeka94

Answer:

x=9

Let's solve your equation step-by-step

12(x−2)+3x=x+12+10x

Step 1: Simplify both sides of the equation.

12(x−2)+3x=x+12+10x

(12)(x)+(12)(−2)+3x=x+12+10x(Distribute)

12x+−24+3x=x+12+10x

(12x+3x)+(−24)=(x+10x)+(12)(Combine Like Terms)

15x+−24=11x+12

15x−24=11x+12

Step 2: Subtract 11x from both sides.

15x−24−11x=11x+12−11x

4x−24=12

Step 3: Add 24 to both sides.

4x−24+24=12+24

4x=36

Step 4: Divide both sides by 4.

4x/4=36/4

x=9

x=9
