The area of triangle ABC is 24 square centimeters. If B = 30° and a = 6 cm, what is the measure of side c? 4 cm 8 cm 16 cm 32 cm

Answer:

16 cm

Step-by-step explanation:

Given : The area of triangle ABC is 24 square centimeters.

To Find: If B = 30° and a = 6 cm, what is the measure of side c?

Solution:

Formula : $Area = \frac{1}{2} \times a \times c \times sin B$

a = 6

Area = 24

B = 30°

Substitute the values in the formula

$24 = \frac{1}{2} \times 6 \times c \times sin 30$

$24 = \frac{1}{2} \times 6 \times c \times \frac{1}{2}$

$24 =3 \times c \times \frac{1}{2}$

$\frac{24 \times 2}{3} =c$

$16=c$

Hence the measure of side c is 16 cm

So, Option c is correct.

Consider the probability that more than 99 out of 157 software users will not call technical support. Assume the probability tha

Rainbow [258]

Answer:

$P(x>99)= 0.468$

Step-by-step explanation:

From the question we are told that:

Sample size 157

Sample mean

$\=x =np$

$\=x =157*0.56$

$\=x = 87.92$

Generally the equation for Standard deviation is mathematically given by

$\sigma=\sqrt{npq}$

$\sigma=\sqrt{157*0.56*0.44}$

$\sigma =6.22$

Therefore

$P(x>99)=P(z>(\frac{99.5-87.92)}{6.22})$

$P(x>99)=P(z>1.86)$

$P(x>99)= 0.468$

What is 26.5 rounded to the nearest hundredth??

blagie [28]

Remember your Number system
After the decimal point to the right, the next digit is the TENTH, and next is HUNDREDTH.

So for 26.5 = 26.500.
The tenth digit is 5, and the Hundredth is 0.
After the hundredth digit which is 0, the next digit is also 0.
The second 0 is not up to 5, so we would not add to the first zero.
(Was it 5, or above, we would have added 1 to first zero)

So the answer is 26.50. If the next digit after the hundredth digit was 5 or more the answer would have been 26.51.

But for this question the answer is 26.50 to the nearest hundredth. Cheers.
