6 0

Step-by-step explanation:

\frac{48}{2x + 7}  =  \frac{40}{5x - 2}  \\ 48(5x - 2) = 40(2x + 7) \\ 240x - 96 = 80x + 280 \\ 240x - 80x = 96 + 280 \\ 160x = 376 \\  \frac{160x}{160}  =  \frac{376}{160}  \\ x = 2.35

Suppose your manager indicates that for a normally distributed data set you are analyzing, your company wants data points betwee
julia-pushkina [17]

Answer:

89.04% of the data points will fall in the given range of z = − 1.6 and z = 1.6      

Step-by-step explanation:

We are given a normally distributed data.

We have to find the percentage of data that lies within the range  z = − 1.6 and z= 1.6

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(-1.6 \leq z \leq 1.6)\\= P(z \leq 1.6) - P(z \leq -1.6)\\\text{Calculating the value from standard normal table}\\= 0.9452 - 0.0548 = 0.8904= 89.04\%

89.04% of the data points will fall in the given range of z = − 1.6 and z= 1.6

Need help on question please!!
Zepler [3.9K]

you'd use the pythagorean theorem.

a^2+b^2=c^2

a is the first leg, b is the second leg, and c is the third leg.

10^2+13^2=c^2

100+169=c^2

269=c^2

take the square root of both sides

16.4=c

16.4cm is your answer!

If f(x) = x^2 is reflected over the x-axis and the shifted 4 units down, what is the equation of the new function, g(x)?
NARA [144]

Answer:

g(x) = -x² - 4

Step-by-step explanation:

In this case, we are only changing <em>a </em>(reflection and vertical shrink/stretch) and <em>k </em>(vertical movement)

<em>k </em>= -4 because we are moving 4 units down

<em>a </em>= -1 because we are just reflecting over the x-axis

Bulled amount collected = $51,000

Operating expenses incurred = $39,000

Account payable = $31000

Cash from issue of common stock = $40,000

Cash invested on land purchase = $21,000
