Answer:

$1440 cm^{3}$

Step-by-step explanation:

To find the volume of an oblique prism you multiply the area of the base times the height of the prism.

V=Bh

where v = volume, B = base length, and h = height. Our base is a rectangle so the area of the base (B) = length times width.

$V=(lw)h\\V=(10*8)18\\V=(80)18\\V=1440 cm^{3}$

The slant height does not matter when finding the volume of a oblique prism.

Answer:

.101501615

.84982392

.901244701

Step-by-step explanation:

For this question use a binomial distribtuion

12C3*.44³*(1-.44)⁹= .101501615

to find at least 4 find the probability of less than 4 and take its compliment

12C0*(1-.44)¹²+12C1*.44*(1-.44)¹¹+12C2*.44²*(1-.44)¹⁰+12C3*.44³*(1-.44)⁹= .15017608

1-.15017608=.84982392

To find less than eight's probability find the proability of at least 8 and take its compliment

12C8*.44⁸(1-.44)⁴+12C9*.44⁹(1-.44)³+12C10*.44¹⁰(1-.44)²+12C11*.44¹¹*(1-.44)+12C12*.44¹²= .098755299

1-.098755299= .901244701

If a number n has exactly 7 divisors, how many divisors does n squared have?

Anna [14]

A number $n=p_1^{a_1}\cdot p_2^{a_2}\cdot\ldots\cdot p_k^{a_k}$ , where $p_k$ are distinct prime numbers, has $(a_1+1)(a_2+1)\cdot\ldots\cdot(a_k+1)$ divisors.

We know that $n$ has 7 divisors. 7 is a prime number, so among the numbers $a_1+1,a_2+1,\ldots,a_k+1$ there is only one that is equal to 7.

So,
$a_k+1=7\\
a_k=6$

That means $n=p^6$ where $p$ is a prime number.
$n^2=(p^6)^2=p^{12}$ , therefore the $n^2$ has $12+1=13$ divisors.

Carly's family traveled 3/10 of the distance to her grandmother's house on Saturday. They traveled 3/7 of the remaining distance

polet [3.4K]

Answer:

3/10 of the total distance to her grandmother's house was traveled on Sunday

Step-by-step explanation:

Carly's family traveled distance of Saturday = $\frac{3}{10}$

Remaining distance = $1-\frac{3}{10}=\frac{7}{10}$

They traveled 3/7 of the remaining distance on Sunday.

So, Distance traveled on Sunday = $\frac{3}{7}(\frac{7}{10})$

Distance traveled on Sunday = $\frac{3}{10}$

Fraction of the total distance to her grandmother's house was traveled on Sunday = $\frac{3}{10}$

Hence 3/10 of the total distance to her grandmother's house was traveled on Sunday

Mice21 [21]

Good evening ,

______

Answer:

y=15x and y= -x

___________________

Step-by-step explanation:

y=15x represents a proportional relationship because y/x=15

y= -x represents a proportional relationship because y/x= -1.
