Volume = base x height x length
= 4 x 8 x 2
= 64(whatever unit)^3(cubed)

balu736 [363]

Answer:

French test

Step-by-step explanation:

We first calculate the scores as percentages:

#Spanish test:

$=\frac{score}{total}\times 100\%\\\\\\=\frac{27}{32}\times 100\%\\\\=84.38\%$

#For the French test, her percentage is:

$=\frac{score}{total}\times 100\%\\\\=\frac{19}{21}\times 100\%\\\\=90.48\%$

Since, 90.48$>84.38%, Claire did better in the French test.

polet [3.4K]

Answer:

Option (A) 0.40951

Step-by-step explanation:

We are given the following information in the question:

P(target) = 0.90

Let the random variable X represent the number of times he hits ring of the target with a shot of the arrow.

The probability distribution of X is

x: 0 1 2 3 4 5

P(x): 0.00001 0.00045 0.00810 0.07290 0.32805 0.59049

The mean of discrete probability distribution is given by:

$\mu = \displaystyle\sum x_iP(x_i)\\\\= 0(0.00001) + 1(0.00045) + 2(0.00810) + 3(0.07290) + 4(0.32805) + 5( 0.59049)\\= 4.5$

Now, we have to evaluate

$P(x$

Option (A) 0.40951 t is the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X.

The line with equation a + 4b = 0 coincides with the terminal side of an angle θ in standard position and cos θ>0 . What is t

Nikitich [7]

Answer:

$\frac{-1}{\sqrt{17} }$

Step-by-step explanation

We have given that equation of line a+4b=0

⇒4b= -a

⇒ $b= \frac{-a}{4}$

slope of line = $tan\theta =\frac{P}{B}= \frac{-1}{4}$

⇒ $tan\theta$ is negative therefore it lies into 4th quadrant

By, Pythagoras theorem $H^2=P^2+B^2$

by putting value of P= -1 & B=4

the value of $H=\sqrt{17}$

with the given condition $cos\theta>0$

i.e. $\theta$ ∈ (3π/2, 2π)

now, $sin\theta= \frac{P}{H}= \frac{-1}{\sqrt{17}}$
