How do you solve this?
Novay_Z [31]

Let's solve your equation step-by-step.


−7x=−2x2+15


Step 1: Subtract -2x^2+15 from both sides.


−7x−(−2x2+15)=−2x2+15−(−2x2+15)


2x2−7x−15=0


Step 2: Factor left side of equation.


(2x+3)(x−5)=0


Step 3: Set factors equal to 0.


2x+3=0 or x−5=0


x=  \frac{-3}{2} or x=5

Answer:


x=    \frac{-3}{2} or x=5


Hope this helps

Determine whether the random variable is discrete or continuous. a. The number of statistics students now reading a book. b. The
andrey2020 [161]

Answer:

Continuous random variables: c and e

Discrete random variables: a, b, d  

Step-by-step explanation:

We have to identify whether the random variable is discrete or continuous.

  • A discrete variable is a variable whose value is obtained by counting.
  • A continuous random variable X takes all values in a given interval of numbers.
  • Thus, a continuous variable can have values in decimals but a discrete random variable cannot take values in decimals.

a. The number of statistics students now reading a book.

Discrete random variable since number of students cannot take decimal values.

b. The number of textbook authors now sitting at a computer.

Discrete random variable since number of textbooks cannot be expressed in decimals but counted.

c. The exact time it takes to evaluate 27 plus 72.

It is a continuous random variable as it may take all values within an interval of time.

d. The number of free dash throw attempts before the first shot is made.

It is a discrete random variable since the number of throws can always be whole number.

e. The time it takes to fly from City Upper A to City Upper B.

Time is a continuous random variable.

HELP ASAP//BRAINLEST+THANKS: Subj:gravity formula stuff
Y_Kistochka [10]

Answer:

6.46

Step-by-step explanation:

h(t) = (1/2)att^{2} + v0t + h0

Origin is at surface of water (h = 0), up is positive.

a = -g = -9.8 m/s^{2}

v0 = 25 m/s

h0 = 50 m

h(t) = -4.9t2 + 25t + 50

Find t when

7 = -4.9t^{2} + 25t + 50

4.9t^{2} - 25t - 43 = 0

t = [1/(2*4.9)] [25 ±√(25^{2} + 4*4.9*43)]

t = (0.102)(25 ± 38.312)

t > 0 ⇒ use only the positive square root

t = (0.102)(25 + 38.312) ≅ 6.46 s

It is 7m above the water at about 6.46 s

Tanya [424]

Answer:

1 Adult ticket=$35

1 Children ticket=$20

Step-by-step explanation:

21C+15A=945

6C+6A=330

we find adult tickets 1st

42C+30A=1890

42C+42A=2310

12A=420

A=35

we will find children ticket next

42c+30a=1890

30c+30a=1650

12c=240

C=20
