Y=-7

the slope is 0, so the x value wouldn’t be in the equation since it would just be 0x which equals 0

Sally likes 225 but not 224; she likes 900 but not 800; she likes 144 but not 145. which does she like - 1600 or 1700?

Pavel [41]

All of Sally's "likes" are squares: 225 = 15², 900 = 30², 144 = 12²

1600 = 40²

Sally "likes" 1600

Terry invested money in a biotech stock whose growth is modeled by the function f(x) = 0.01(2)x, where x represents number of da

strojnjashka [21]

Answer:

The average rate of change is 1.275

Step-by-step explanation:

The average rate of change of f(x) from x=a to x=b is given by:

$\frac{f(b)-f(a)}{b-a}$

The money Terry invested is modeled by the function $f(x)=0.01(2)^x$ where x represents number of days.

The average rate of change from day 2 to day 10 is given by:

$\frac{f(10)-f(2)}{10-2}$

$f(10)=0.01(2)^{10}=10.24$

$f(2)=0.01(2)^{2}=0.04$

The average rate of change becomes:

$\frac{10.24-0.04}{8}$

$=\frac{10.2}{8}=1.275$

The expression P(z > –1.53) represents the area under the standard normal curve above a given value of z. Find P(z > –1.53

Damm [24]

We can only look up the value in the normal distribution table if the probability of z is LESS than a certain value AND the value is positive.
If the probability of z is MORE than the value, then you need to do 1 minus the probability.
I.e. 1 - 0.93699
[0.93699 is found in the normal distribution table, searching for 1.53]
However, since the value (-1.53) is also negative, you need to do 1 minus AGAIN.
I.e. 1 - 0.93699

Since you have to do both, the answer should be obtained as follows:
1 - (1 - 0.93699) = 0.93699

Sorry for the terrible explanation :/
And apologies if anything is incorrect. Hope this helped though!

write the equation of the line that passes throughout (-1,5) and has a slope of 3 in point-slope form

SpyIntel [72]

The point-slope form is:
$y - k = m(x-h)$

So, here, you just plug in values:
$y - 5 = 3(x+1)$

It would be + 1 because remember, the '-' sign just means the opposite of, not subtraction in this case. Also, m = slope.
