Answer:

D. 140

Step-by-step explanation:

D = b² - 4ac

So, let's identify our values.

a = 2

b = -10

c = -5

Now, we can plug in our values.

D = -10² - 4(2)(-5)

D = 100 + 40

D = 140

Answer:

D. 140

Step-by-step explanation:

In the equation, $ax^2+bx+c=0,$ the discriminant can be found with $b^2-4ac$ .

In this equation,

the discriminant would be: $(-10)^2-4(2)(-5)=100+40=140$

An Internet reaction time test asks subjects to click their mouse button as soon as a light flashes on the screen. The light is

Ganezh [65]

Answer:

(a) 0.20

(b) 31%

Step-by-step explanation:

The random variable Y models the amount of time the subject has to wait for the light to flash.

The density curve represents that of an Uniform distribution with parameters a = 1 and b = 5.

So, $Y\sim Unif(1,5)$

(a)

The area under the density curve is always 1.

The length is 5 units.

Compute the height as follows:

$\text{Area under the density curve}=\text{length}\times \text{height}$

$1=5\times\text{height}\\\\\text{height}=\frac{1}{5}\\\\\text{height}=0.20$

Thus, the height of the density curve is 0.20.

(b)

Compute the value of P (Y > 3.75) as follows:

$P(Y>3.75)=\int\limits^{5}_{3.75} {\frac{1}{b-a}} \, dy \\\\=\int\limits^{5}_{3.75} {\frac{1}{5-1}} \, dy\\\\=\frac{1}{4}\times [y]^{5}_{3.75}\\\\=\frac{5-3.75}{4}\\\\=0.3125\\\\\approx 0.31$

Thus, the light will flash more than 3.75 seconds after the subject clicks "Start" 31% of the times.

(c)

Compute the 38th percentile as follows:

$P(Y$

Thus, the 38th percentile is 2.52 seconds.

Parallel to y=2÷3x+6 Passes through (6,7)

erma4kov [3.2K]

Answer:

Step-by-step explanation:

Parallel to y=2÷3x+6

Passes through (6,7)

slope is (2/3)

Solve for when y is 7 and x is 6.

take out the + 6 at the end because it doesnt change the slope. replace with b. (y=mx+b)

replace y and x.

7 = (2/3)(6)+b

solve for b and then put it back into the equatio and make 6 and 7 into x and y again.

If the Laffite family deposits $8500 in savings account at 6.75% interest, compounded continuously, how much will be in the acco

vitfil [10]

Answer:

Option b

Step-by-step explanation:

We have a compound interest problem. With an annual interest rate of 0.675 and an initial payment of 8500, with t = 25 years

Then you must use the annual compound interest formula, which is represented by a growing exponential function:

$y = e ^{ht}$

Where:

h is the interest rate of 0.675

y is the money in the savings account as a function of time

Then substitute the values in the formula and we have:

$y = e ^{0.675(25)}$

$y = 45,950.57$
