Answer: First multiply 10 by 20.5 because x represents the number of weeks.  You get 205.  Next add 165.85 to that and you get 370.85 as your final answer.

<u>Answer:</u>

The correct answer option is \frac { 4 } { 4 9 }.

<u>Step-by-step explanation:</u>

We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).

Total number of days in a week = 7

Number of days in weekend = 2

Probability of being born on weekend = \frac { 2 } { 7 }

P (both parents were born on weekend) = \frac{2}{7} \times \frac{2}{7} = 4/49

Answer is –4/5

Rearrange the equation to make y the subject

5y = –4x – 35

y = –4/5 x – 7

If the line is parallel to the other line, they both have the same gradients but different y-intercepts, so the gradient is just as is.

Over the entire six years that students attend an ohio elementary school, they are absent, on average, 28 days due to influenza.
qaws [65]
The probability that the sample mean is less than 30 school days will be given as follows:
the z-score is given by:
z=(x-μ)/σ
where
μ- stand deviation
σ-mean
thus the z-score of our information is:
z=(30-28)/9
z=0.222222
hence the probability that the sample mean is less than 30 will be:
P(x<30)=0.5871~58.71%

Determine the value(s) of k such that the system of linear equations has the indicated number of solutions. (Enter your answers
Ratling [72]

Answer:

k=3

Step-by-step explanation:

The given system of equations are

9x+ky=24

kx+y=8

We need to find the value of k if the given system of equation have infinite number of solutions.

If two equations a_1x+b_1y+c_1=0 and a_2x+b_2y+c_2=0 have infinite number of solutions, then

\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}

Using this we get

\dfrac{9}{k}=\dfrac{k}{1}=\dfrac{-24}{-8}

\dfrac{9}{k}=\dfrac{k}{1}=3

\dfrac{k}{1}=3

k=3

Therefore, the value of k is 3.
