grin007 [14]3 years ago
3 0

Step-by-step explanation:

We have,

l =5ft

b=2ft

h=3ft

volume(v) = l \times b \times h

v = (l*b*h)

v = (5*2*3)ft

v = (30)ft

.•. v = 30ft

UkoKoshka [18]

Answer:

The probability that 8 mice are​ required is 0.2428.

Step-by-step explanation:

Given : A scientist inoculates​ mice, one at a​ time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.

To find : What is the probability that 8 mice are​ required? The probability that that 8 mice are required is nothing ?

Solution :

Applying binomial distribution,

P(X=r)=^nC_r p^rq^{n-r}

Where, p is the probability of success p=\frac{2}{7}

q is the probability of failure q=1-p, q=1-\frac{2}{7}=\frac{5}{7}

n is total number of trials n=8

r=3

Substitute the values,

P(X=3)=^8C_3 (\frac{2}{7})^3 (\frac{5}{7})^{8-3}

P(X=3)=\frac{8!}{3!5!}\times \frac{8}{343}\times (\frac{5}{7})^{5}

P(X=3)=\frac{8\times 7\times 6}{3\times 2\times 1}\times \frac{8}{343}\times \frac{3125}{16807}

P(X=3)=0.2428

Therefore, the probability that 8 mice are​ required is 0.2428.

The leg of a right triangle are 3 units and 10 units. What is the length of the hypotenuse? Round your answer to the nearest hun
Andreas93 [3]
Hey there! This is gonna require the Pythagorean Theorem which is<span> a^2 + b^2 = c^2
</span>
a and b in this case are the legs while c is the hypotenuse! So, we can just plug in the numbers we know!

3^2 + 10^2 = c^2

9 + 100 = c^2

109 = c^2

And then take the square root of 109 to get the hypotenuse.

<span>10.4403065089 = c
</span>
Since we need to round to the nearest hundredth, though, it would be 10.44



I hope that helps! Feel free to let me know if you have any questions!

Daniel wanted to know his approximate score on the final exam for his mathematics class. His professor hinted that his score was
hammer [34]

Answer:   The raw score for Daniel's exam grade is 101.69.

Step-by-step explanation:

For x be any random variable.

Formula for z-score :

z=\dfrac{x-\mu}{\sigma} , where \mu = population mean

\sigma = population standard deviation.

Let x be the raw score for Daniel's exam grade.

As per given , we have

\mu=90 , \sigma=7 and z= 1.67 , put these values in the above formula , we get

1.67=\dfrac{x-90}{7}\\\\\Rightarrow\ x-90=7(1.67)=11.69\\\\\Righarrow\ x=11.69+90=101.69

Hence, the raw score for Daniel's exam grade is 101.69.
