Answer:

y = (7/2)x - 2

Step-by-step explanation:

Use slope-intercept formula for linear equations y = mx + b

x and y show what points are on the line. We know (4, 12). x= 4 and y = 12

b is the y-intercept, which b = -2.

m is the slope.

To write the equation, you need the slope and y-intercept. Find the slope by putting x, y and b into the formula.

y = mx + b

12 = 4m - 2

14 = 4m

14/4 = m

m = 7/2

Put "m" into the formula with "b"

y = (7/2)x - 2

Kate bad $2,251 in here bank account. Currently, she has $1,958 in her account. What is the approximate percent of decrease in h

Fiesta28 [93]

Answer:

The answer is: 13%.

Step-by-step explanation:

At first, Kate had $2,251. Then her new balance was $1,958. The difference between the two is the amount spent:

$2,251 - $1,958 = $293.

The difference is the ratio of the amount spent divided by the original amount, to provide the decrease:

$293 / $2,251 = .13 or 13% (Approximately)

Hope this helps! Have a great day!

Calculate the quotient below and give your answer in scientific notation.<br> 2.64*10^-3\8.0*10^0

Zolol [24]

Answer:

The quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$

Step-by-step explanation:

We need to find quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$

We know that $10^0=1$

Now solving:

$\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033$

Writing it in scientific notation

$0.00033\\=3.3\times10^{-4}$

So, the quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$

A coach wants to know if soccer players who warm up before a game will score more points than those who don't warm up. He will b

11Alexandr11 [23.1K]

The correct answer is the last option.

Since the coach is studying the two different groups, the results will be more meaningful if the groups are compared to one another as opposed to the players. It would also make more sense to study the mean (or average) of the points scored, rather than the standard deviation (which is essentially a measure of how spread out a set of numbers are).
