Answer:

a= 100

b= 15

c= 165

Step-by-step explanation:

Since a and the 80 are supplementary (on a straight line), you need to subtract 80 from 180 to get a.

180-80= 100

a=100

a+b+c= 180, because all angles of a triangle add up to 180 degrees. 100+65+b=180

165+b=180

b=15

C is supplementary to b, so 180-15=165

c=165

Answer:

a is 100 b is 16 and c is 75

Step-by-step explanation:

Answer:

B. 50°

Step-by-step explanation:

∠PLM+ ∠PML =60+70 =130°

So, ∠MPL = 180°-130°=50°

According to the opposite angle theorem,

∠ KPN = ∠MPL which is 50°

Answer:

sorry this took a moment

Answer:

a) P(NP/L)  = 0.1

b) P(P/L) = 0.9

c) P(P) = 0.666

d) P(L/P) = 0.945

e) P(NL U NP) = 0.37

Step-by-step explanation:

given that;

P  = passing the course, NP = Not passing the course, L = Using lab, NL = not using Lab

P(L) = 70% = 0.7,             P(NL) = 30% = 0.3

P(P/L) = 90% = 0.9

P(P/NL) = 12% = 0.12

a)

the probability of not passing the course given that the student went to the Learning Lab

P(NP/L) = 1 - P(P/L)

P(NP/L)  = 1 - 0.9

P(NP/L)  = 0.1

b)

the probability of using the Learning Lab and passing the course

P(P/L) = 0.9

c)

the probability of passing the class

P(P) = P(P/L) * P(L) + P(P/NL) * P(NL)

= (0.9 * 0.7) + (0.12 * 0.3)

P(P) = 0.666

d)

the probability that a student utilized the Learning Lab given the condition that the student passed the class

P(L/P) = [P(P/L) * P(L)] / P(P)

P(L/P) = (0.9 * 0.7) / 0.666 = 0.63/0.666

P(L/P) = 0.945

e)

the probability of not using the Learning Lab or not passing the class

P(NL U NP) = P(NL) + P(NP) - P(NP n NL)

= 0.3 + 0.334 - (0.88 * 0.3 )

= 0.634 - 0.264  

P(NL U NP) = 0.37

Answer:

The original price of the school supplies was $19

Step-by-step explanation:

Percentages

If the original price of the school supplies is x, and being the tax rate of 6%, then the after-tax price is x+6/100x=1.06x.

We know that final price, thus:

1.06x=20.14

x=20.14/1.06=19

The original price of the school supplies was $19

Answer:

y = 0.1x+200

Step-by-step explanation:

First, let's establish that:

x is independent

y is dependent

Basically, the value of y will depend on what x is.

The problem states that the slope of the line is Dave's comission, so since he makes 10% of comission, we can make the slope as 0.1x (mx)

The problem also states that the y intercept (b) is Dave's base salary, and earlier in the problem it states that his base salary is $200 a week. Therefore, b=200

now, the equation is:

y=0.1x+200

Answer:

Obtuse

Step-by-step explanation:

You can see visually that it's wider than a right angle, and that's it's more than 90°

The angle is more than 90 degrees, as a result, it is stated as the obtuse angle. Option D is correct.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

We have to state the name type of the angle.

Any angle larger than 90° is considered obtuse. A straight angle is one with a measurement of 180°: Angles equal to 0° are referred to as zero angles. Complementary angles are those whose total of the measurements is exactly 90°: Angles that have supplementary angles are those whose total of the measurements is 180°.

It is observed that the angle is more than 90 degrees.

Thus, the angle is more than 90 degrees, as a result, it is stated as the obtuse angle. Option D is correct.

Step-by-step explanation:

Answer:

The differential equation for the amount of salt A(t) in the tank at a time  t > 0 is [tex]\frac{dA}{dt}=12 - \frac{2A(t)}{500+t}[/tex].

Step-by-step explanation:

We are given that a large mixing tank initially holds 500 gallons of water in which 50 pounds of salt have been dissolved. Another brine solution is pumped into the tank at a rate of 3 gal/min, and when the solution is well stirred, it is then pumped out at a slower rate of 2 gal/min.

The concentration of the solution entering is 4 lb/gal.

Firstly, as we know that the rate of change in the amount of salt with respect to time is given by;

[tex]\frac{dA}{dt}= \text{R}_i_n - \text{R}_o_u_t[/tex]

where, [tex]\text{R}_i_n[/tex] = concentration of salt in the inflow [tex]\times[/tex] input rate of brine solution

and [tex]\text{R}_o_u_t[/tex] = concentration of salt in the outflow [tex]\times[/tex] outflow rate of brine solution

So, [tex]\text{R}_i_n[/tex] = 4 lb/gal [tex]\times[/tex] 3 gal/min = 12 lb/gal

Now, the rate of accumulation = Rate of input of solution - Rate of output of solution

                                                = 3 gal/min - 2 gal/min

                                                = 1 gal/min.

It is stated that a large mixing tank initially holds 500 gallons of water, so after t minutes it will hold (500 + t) gallons in the tank.

So, [tex]\text{R}_o_u_t[/tex] = concentration of salt in the outflow [tex]\times[/tex] outflow rate of brine solution

             = [tex]\frac{A(t)}{500+t} \text{ lb/gal } \times 2 \text{ gal/min}[/tex] = [tex]\frac{2A(t)}{500+t} \text{ lb/min }[/tex]

Now, the differential equation for the amount of salt A(t) in the tank at a time  t > 0 is given by;

= [tex]\frac{dA}{dt}=12\text{ lb/min } - \frac{2A(t)}{500+t} \text{ lb/min }[/tex]

or [tex]\frac{dA}{dt}=12 - \frac{2A(t)}{500+t}[/tex].

The answer is 63/256

Step-by-step explanation:

edge 2020

The probability of getting exactly 5 “heads” in 10 coin flips is; 63/256

The formula for Binomial Probability is;

P(X = r) = nCr * p^(r) * (1 - p)^(n - r)

Probability of getting a head = 0.5

Thus;

P(X = 5) = 10C5 * 0.5⁵ * (1 - 0.5)⁽¹⁰ ⁻ ⁵⁾

P(X = 5) = 0.2461 = 63/256

Step-by-step explanation:

Step 1: Write equation

(a + b)4 = y

Step 2: Solve for a

Answer: Because we are trying to find the x-intercepts and the y-intercepts That would be (C)

Step-by-step explanation:

Self explanatory question, you set a quadratic equation to zero

For example: x 2 – 6 x = 16 equals to x 2 – 6 x – 16 = 0

Then, you would factor, that equals to (x – 8)( x + 2) = 0

(X-8)=0 (X+2)=0

X+2=0

-2 =-2

X=-2

X-8=0

+8 =+8

X=-8

To check you would simply plug in the values into the quadratic equation. They would both equal 16=16
