A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independen

Andrews [41]

Answer:

0.044

Step-by-step explanation:

n=9,p=0.9, x =6.

Apply Binomial probability we get

Sum P(x)=C(n,x) $p^{x} (1-p)^{n-x}$ for x=6

Putting in the formula ,

we get

P(x) = C(9,6) $0.9^{6} 0.1^{3}$

84 X 0.531441 X 0.001

= 0.044

Dale says the ratios 3:5 and 2:10 are equivalent. Is He correct? Explain

Mnenie [13.5K]

Answer:

No, Dale Isn't correct because 3:5 is greater than 2:10

Step-by-step explanation:

3:5 and 2:10 is the same as in $\frac{3}{5}$ and $\frac{2}{10}$

First Find the least common denominator or LCM of the two denominators:

LCM of 5 and 10 is 10

Next, find the equivalent fraction of both fractional numbers with denominator 10

For the 1st fraction, since 5 × 2 = 10,

$\frac{3}{5} =\frac{3*2}{5*2} =\frac{6}{10}$

Likewise, for the 2nd fraction, since 10 × 1 = 10,

$\frac{2}{10} =\frac{2*1}{10*1} =\frac{2}{10}$

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

$\frac{6}{10} >\frac{2}{10} Or\frac{3}{5} >\frac{2}{10}$

Hence, $\frac{3}{5}$ is <u>Greater than </u> $\frac{2}{10}$

Hence, 3:5 is <u>Greater than </u>2:10

Sate the equation that relates arc length to central angle

kobusy [5.1K]

S =rO
The length of an arc is related to the radius and the central angle in the formula. s = rθ. where s is the arc length, r is the radius and θ is the angle in radians. Remember that to convert from radians to degrees, 2π radians = 360 degrees, so if φ = the angle in degrees, then the equation becomes this:

. Jill is 48 5/8 inches tall. Lei is 47.5 inches tall. What is the difference in their heights? a. 0.125 inches b. 1.08 inches c

Roman55 [17]

Explanation:

First we write the fraction as a decimal. 5/8 is 0.625, so the height of Jill is 48.625 inches.

The difference is:

$48.625-47.5=1.125$

Answer:

c. 1.125 inches
