Does anyone know this??

STALIN [3.7K]

Hi there! The answer is C.

Explanation:
We have the following equation:

$\frac{8}{15} = \frac{x}{6}$
To solve this type of equation (with an x in the denominator of a fraction) we must cross-multiply the numerator and the denominator.

$15 \times x = 8 \times 6$
Multiply

$15x = 40$
Divide both sides by 15.

$x = \frac{40}{15} = 2 \frac{2}{3}$
~ Hope this helps you!

What is the equation of the line that is perpendicular to the line y=3/5xplus 10 and passes through the point (15,-5)?

Allisa [31]

Step-by-step explanation:

a general line equation is

y = ax + b

the original line is

y = 3/5 x + 10

the factor of x is always the slope (inclination of the line).

it is "y change/x change".

the slope of a perpendicular line (angle of 90°) is turning the slope of the original line upside-down and flips the sign.

so, it is -5/3.

we use the point information to get the right "b" for our new line :

-5 = -5/3 × 15 + b

-5 = -5×5 + b

-5 = -25 + b

b = 20

so, the perpendicular line equation going through (15, -5) is

y = -5/3 x + 20

What is -2x – 10 = 4????

Sunny_sXe [5.5K]

Answer:

x = -7

Step-by-step explanation:

-2x - 10 = 4

-2x = 14 | Add 10 to both sides

x = -7 | Divide both sides by -2

In general, the probability that a blood donor has Type A blood is 0.40.Consider 8 randomly chosen blood donors, what is the pro

postnew [5]

Answer:

The probability that more than half of them have Type A blood in the sample of 8 randomly chosen donors is P(X>4)=0.1738.

Step-by-step explanation:

This can be modeled as a binomial random variable with n=8 and p=0.4.

The probability that k individuals in the sample have Type A blood can be calculated as:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{8}{k} 0.4^{k} 0.6^{8-k}\\\\\\$

Then, we can calculate the probability that more than 8/2=4 have Type A blood as:

$P(X>4)=P(X=5)+P(X=6)+P(X=7)+P(X=8)\\\\\\P(x=5) = \dbinom{8}{5} p^{5}(1-p)^{3}=56*0.0102*0.216=0.1239\\\\\\P(x=6) = \dbinom{8}{6} p^{6}(1-p)^{2}=28*0.0041*0.36=0.0413\\\\\\P(x=7) = \dbinom{8}{7} p^{7}(1-p)^{1}=8*0.0016*0.6=0.0079\\\\\\P(x=8) = \dbinom{8}{8} p^{8}(1-p)^{0}=1*0.0007*1=0.0007\\\\\\\\P(X>4)=0.1239+0.0413+0.0079+0.0007=0.1738$
