Answers
Answer:
The midpoint is ( 1, -1.5)
Step-by-step explanation:
To find the midpoint
Add the x coordinates of the endpoints and divide by 2 to get the x coordinate of the midpoint
(5+-3)/2 = 2/2 = 1
Add the y coordinates of the endpoints and divide by 2 to get the y coordinate of the midpoint
(3+-6)/2 = -3/2 = -1.5
The midpoint is ( 1, -1.5)
Answer:
mid point = 1, -1.5
Step-by-step explanation:
mid point between two points C(5, 3) and D(-3, -6)
M = (x1 + x2)/2 , (y1 + y2)/2
mid point = (5 + (-3)) / 2 , (3 + -6)/2
mid point = 2/2 , -3/2
mid point = 1, -1.5
EXAMPLE 5 If f(x, y, z) = x sin(yz), (a) find the gradient of f and (b) find the directional derivative of f at (1, 2, 0) in the direction of v = i + 4j − k. SOLUTION (a) The gradient of f is ∇f(x, y, z) = fx(x, y, z), fy(x, y, z), fz(x, y, z)
Answers
Answer:
a) f = sin(yz)i + xzcos(yz)j + xycos(yz)kb) -2Step-by-step explanation:
Given f(x, y, z) = x sin(yz), the formula for calculating the gradient of the function is expressed as ∇f(x, y, z) = fx(x, y, z)i+ fy(x, y, z)j+fz(x, y, z)k where;
fx, fy and fz are the differential of the functions with respect to x, y and z respectively.
a) ∇f(x, y, z) = sin(yz)i + xzcos(yz)j + xycos(yz)k
The gradient of f = sin(yz)i + xzcos(yz)j + xycos(yz)k
b) Directional derivative of f at (1,2,0) in the direction of v = i + 4j − k is expressed as ∇f(1, 2, 0)*v
∇f(1, 2, 0) = sin(2(0))i +1*0cos(2*0)j + 1*2cos(2*0)k
∇f(1, 2, 0) = sin0i +0cos(0)j + 2cos(0)k
∇f(1, 2, 0) = 0i +0j + 2k
Given v = i + 4j − k
∇f(1, 2, 0)*v (note that this is the dot product of the two vectors)
∇f(1, 2, 0)*v = (0i +0j + 2k)*(i + 4j − k )
Given i.i = j.j = k.k =1 and i.j=j.i=j.k=k.j=i.k = 0
∇f(1, 2, 0)*v = 0(i.i)+4*0(j.j)+2(-1)k.k
∇f(1, 2, 0)*v = 0(1)+0(1)-2(1)
∇f(1, 2, 0)*v =0+0-2
∇f(1, 2, 0)*v= -2
Hence, the directional derivative of f at (1, 2, 0) in the direction of v = i + 4j − k is -2
Plot 2 1/2 and 1 5/6 on the number line below.

Between each of the integers, 0, 1, 2, 3, etc., the space is divided into 6 units. We can use this to our advantage.
Since 1/2 = 2/4 = 5/10 = 3/6 = ....., thus:
2 1/2 = 2 3/6. Now we can easily plot points on the number line.
2 3/6 = 2 units and 3 sub units.

B. The results are likely to be representative because a championship team is most likely representative of the entire league.
Step-by-step explanation:
278 303 186 292 276 205 208 236 278 198 208
Arranged in ascending order is
186 198 205 208 208 236 276 278 278 292 303
Mean = (186 +198+ 205+ 208 +208 +236 + 276+ 278 +278+ 292 +303)/11
Mean =2668/11
Mean= 242.5 pounds
Median = the middle number
Median= 236 pounds
Mode = highest occuring number(s)
Mode= 208 and 278 pounds
Range= highest number- smallest number
Range=303-186
Range=117 pounds
Mid-range= range/2
Mid-range= 117/2
Mid-range= 58.5 pounds
P=x-2 ÷ x+1 for what value of x is P undefined
Answers
Answer:
x = - 1
Step-by-step explanation:
P = \(\frac{x-2}{x+1}\)
the denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
x + 1 = 0 ( subtract 1 from both sides )
x = - 1
P is undefined when x = - 1

The payoffs in the casino game Chuck-a-Luck are determined by the number of threes that appear when a set of four-sided dice (a four-sided die has the numbers 1, 2, 3, and 4 on its faces) are tossed.a.If 20 dice are tossed, what is the probability that at most 4 threes will appear?b. If 12000 dice are tossed, what is the probability that at most 2990 threes will appear?
Answers
The probability of at most 4 threes appearing when 20 dice are tossed is 0.0756 and The probability of at most 2990 threes appearing when 12000 dice are tossed is 0.054.
a. The probability of at most 4 threes appearing when 20 dice are tossed can be calculated using the cumulative distribution function of the binomial distribution with parameters n = 20 and p = 1/4 (the probability of rolling a three on a single die). Using a binomial cumulative distribution calculator or a statistical software package, the result is approximately 0.0756.
b. The probability of at most 2990 threes appearing when 12000 dice are tossed can be calculated using the cumulative distribution function of the binomial distribution with parameters n = 12000 and p = 1/4. Using a binomial cumulative distribution calculator or a statistical software package, the result is approximately 0.0544.

Answers
The experimental probability that the next train to pull into Lakeside Station will be full is 7/10.
The experimental probability of the next train to pull into Lakeside Station being full can be calculated by dividing the number of times a full train occurred by the total number of trains observed.
Given that out of the last 20 trains, 14 were full, we can express the experimental probability as a fraction:
P(full) = Number of full trains / Total number of trains observed
P(full) = 14 / 20
Simplifying the fraction, we get:
P(full) = 7 / 10
Therefore, the experimental probability that the next train to pull into Lakeside Station will be full is 7/10.

Value of base and hypotenuse of triangle are 9√3 and 18 respectively.
Define right triangleA right triangle is a triangle with one interior angle measuring 90 degrees, known as a right angle. The side opposite to the right angle is called the hypotenuse, and the other two sides are known as the legs of the right triangle. The length of the hypotenuse can be found using the Pythagorean theorem, that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.
Height of triangle=9
Base of triangle=y
Hypotenuse of triangle=x
Using trigonometric ratio
Sin30°=Height/Hypotenuse
½=9/x
x=18
