Question 1
If mZHOE =19° and mZHOP=48°, find mZEOP.
H
O
Р
Answer:
mEOP is 29°
Step-by-step explanation:
mHOP is 48° and mHOE is 19°, so to get the missing angle you subtract the smaller value from the total to get 29°
- 19-48=29
What is the measure of angle x? Round to the
nearest tenth. .
28
21
xº
Answer:
x =53.1
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side/ adjacent side
tan x = 28 /21
Take the inverse tan of each side
tan ^-1 (tan x) = tan ^-1 (28/21)
x = 53.13010235
Rounding to the nearest tenth
x =53.1
which expression could be used to determine the product of -4 and 3 1/4
Answer:
B (-4)(3) + (-4)(1/4)
Step-by-step explanation:
We must find the product of -4 and 3 1/4, which is (-4)(3 1/4). We know that 3 1/4 = 3 + 1/4, so we substitute that to the expression we want.
(-4)(3 1/4) = (-4)(3 + 1/4)
Using the distributive property, we distribute the -4 to the 3 and the 1/4 and the expression becomes
(-4)(3 + 1/4) = (-4)(3) + (-4)(1/4)
I hope this helps! :)
does anyone know how to solve this
Step-by-step explanation:
7 + 2x + 3 = x + 10
2x - x = 10 - 7 - 3
x = 0
What?
I don't think this helps...
Answer:
x = 0.
Step-by-step explanation:
The distance between the point U and W are x + 10 and 2x + 3 + 7 so we can make the following equation:
x + 10 = 2x + 3 + 7
x + 10 = 2x + 10
Subtract 10 from both sides:
x = 2x
Subtract x from both sides:
0 = x
x = 0
Consider a different experiment: EXPERIMENT: A bag contains 3 red balls, 4 blue balls, 4 green balls and 3 yellow balls. One ball is drawn at random and then returned to the bag. Then a ball is drawn again, possibly the same one or a different one.
(a) Specify the sample space (set of outcomes) and probability distribution of the outcomes.
(b) What is the probability that both balls drawn were red balls?
(c) Starting over with all 14 balls back in the bag, what is the probability that both draws were balls of different colors?
Answer:
a) Sample space = RR, RB, RG, RY, BB, BR, BG, BY, GG, GR, GB, GY, YY, YR, YB, YG .
probability distribution of outcomes
= (3/14*3/14), (3/14*4/14), (3/14*4/14), (3/14*3/14), (4/14 *4/14 ), (4/14*3/14), (4/14 * 4/14), (4/14 * 3/14 ), ( 4/14 *4/14 ), (4/14*3/14), ( 4/14 *4/14 ),
(4/14*3/14), (3/14 *3/14 ), (3/14*3/14), (3/14 *4/14 ), ( 3/14 * 4/14 )
b) 0.0459
c) ( 3/14 * 4/14 ) + ( 3/14 * 4/14 ) + ( 3/14 * 3/14 ) + ------ ( 3/14 * 4/14 )
Step-by-step explanation:
Total number of balls = 3 + 4 + 4 + 3 = 14 balls
3 Red balls = 3/14
4 blue balls = 4/14
4 green balls = 4/14
3 yellow balls = 3/14
a) Determine the sample space and probability distribution of outcomes
since ball is drawn with replacement
Sample space = RR, RB, RG, RY, BB, BR, BG, BY, GG, GR, GB, GY, YY, YR, YB, YG .
i.e. The sample space has 16 possible combination
probability distribution of outcomes
= (3/14*3/14), (3/14*4/14), (3/14*4/14), (3/14*3/14), (4/14 *4/14 ), (4/14*3/14), (4/14 * 4/14), (4/14 * 3/14 ), ( 4/14 *4/14 ), (4/14*3/14), ( 4/14 *4/14 ),
(4/14*3/14), (3/14 *3/14 ), (3/14*3/14), (3/14 *4/14 ), ( 3/14 * 4/14 )
b) Determine P( R and R )
P ( R and R ) = 3/14 * 3/14
= 9/196 = 0.0459
C) Determine probability of drawing two different balls
P( R and B ) + P ( R and G ) + P ( R and Y ) + ------ P ( Y and G )
= ( 3/14 * 4/14 ) + ( 3/14 * 4/14 ) + ( 3/14 * 3/14 ) + ------ ( 3/14 * 4/14 )

Answer:
(x, y) = (-7, 5)
Step-by-step explanation:
I find a graphing calculator to be useful for solving equations by graphing. The graph shows the solution to be ...
(x, y) = (-7, 5)
__
In these equations, the y-coefficients are the same, so we can eliminate y by subtracting the first equation from the second.
(4x -6y) -(-2x -6y) = (-58) -(-16)
6x = -42 . . . . . . . . . simplify
x = -7 . . . . . . . . divide by 6
Substituting into the first equation gives ...
-2(-7) -6y = -16
6y = 30 . . . . . . . . . . add 16+6y to both sides
y = 5 . . . . . . . . .divide by 6
The solution is (x, y) = (-7, 5).

Answer:
5 (cm)
Step-by-step explanation:
1. according to the condition in ΔABC: AC=BC, m∠C=90°. Then m∠B=m∠A=45° and
2. x=AC=AB/√2; ⇔ x=5 (cm).
Answer:
x=5 cm
Step-by-step explanation:
triangle ABC is an isoceles triangle
so BC=AC and angle A=angle B
BC=X and angle A=theta
angle B and angle A both is theta degree because base angles of an isosceles triangle are equal
to find angle A and B
angle A + angle B + angle c=180 degree (sum of interior angles of a triangle)
theta + theta +90=180
2theta=180-90
2theta=90
theta=90/2
theta=45 degree
sin both angle A and angle B are theta their value is 45 degree.
For side x
now using pythagoras theorem
take theta as reference angle
using sin rule
sin 45=opposite/hypotenuse

Judson wants to perform a X2 test of independence between name length and population. What is the expected count for the cell corresponding to cities with more than 250,000 residents whose name has less than 8 characters?
The expected count for the cell corresponding to cities with more than 250,000 residents whose name has less than 8 characters is A = 33.45
What is the probability distribution?A mathematical function called a probability distribution explains the likelihood of many alternative values for a variable. Graphs or probability tables are frequently used to represent probability distributions.
The mean of probability distribution is also known as expected value. It is denoted by E ( X ). E(X), or mean μ of a discrete random variable X is calculated by multiplying each value of the random variable by its probability and taking the sum of the values.
E ( X ) = μ = ∑x P ( x )
Given data ,
To find the expected count for the cell corresponding to cities with more than 250,000 residents whose name has less than 8 characters, we need to calculate the expected count for that cell using the formula:
Expected Count = (row total * column total) / grand total
The row total for cities with more than 250,000 residents is 99, and the column total for names with less than 8 characters is 100. The grand total is 296
Expected Count = (99 * 100) / 296
Expected Count ≈ 33.45
Therefore , the expected count for the cell corresponding to cities with more than 250,000 residents whose name has less than 8 characters is approximately 26.67
Hence , the distribution is 33.45

use algebraic manipulation to find the minimum sum-of-products expression for the function x1x2'x3' + x1x2x4+x1x2'x3x4'
The minimum sum-of-products expression for the given Boolean function is x₁[x₂'x₃' + x₂'x₄' + x₂x₄] .
To find the minimum sum-of-products expression for the given Boolean function, we can use algebraic manipulation techniques, including Boolean algebra laws and Karnaugh maps.
Let's start with the given expression:
F = x₁x₂'x₃' + x₁x₂x₄ + x₁x₂'x₃x₄'
F = x₁[x₂'x₃' + x₂x₄ + x₂'x₃x₄']
F = x₁[x₂'(x₃' + x₃x₄') + x₂x₄] ....(1)
As we know that the Boolean rule as:
a + bc = (a + b)(a + c)
a' + a = 1
As per the equation (1),
F = x₁[x₂'{(x₃' + x₃)(x₃'+x₄') + x₂x₄]
F = x₁[x₂'x₃' + x₂'x₄' + x₂x₄]
Thus, the minimum sum-of-products expression for the given Boolean function is x₁[x₂'x₃' + x₂'x₄' + x₂x₄] .

Is this graph standard, vertex, or intercept?
Step-by-step explanation:
It's an intercept graph
Suppose F⃗ (x,y)=(x+3)i⃗ +(6y+3)j⃗ . Use the fundamental theorem of line integrals to calculate the following.
(a) The line integral of F⃗ along the line segment C from the point P=(1,0) to the point Q=(3,3).
∫CF⃗ ⋅dr⃗ =?
(b) The line integral of F⃗ along the triangle C from the origin to the point P=(1,0) to the point Q=(3,3) and back to the origin.
∫CF⃗ ⋅dr⃗ =?
In order to use the fundamental theorem of line integrals, you need to find a scalar potential function - that is, a scalar function f(x, y) for which
grad f(x, y) = F(x, y)
This amounts to solving for f such that
∂f/dx = x + 3
∂f/∂y = 6y + 3
Integrating both sides of the first equation with respect to x gives
f = 1/2 x ^2 + 3x + g(y)
Differentiating with respect to y gives
∂f/∂y = dg/dy = 6y + 3
Solving for g gives
g = ∫ (6y + 3) dy = 3y ^2 + 3y + C
and hence
f(x, y) = 1/2 x ^2 + 3x + 3y ^2 + 3y + C
(a) By the fundamental theorem, the integral of F along any path starting at the point P (1, 0) and ending at Q (3, 3) is
∫ F(x, y) • dr = f (3, 3) - f (1, 0) = 99/2 - 7/2 = 46
(b) Now we're talking about a closed path, so the integral is simply 0. We can verify this by checking the integral over the origin-containing paths:
• From the origin to P :
∫ F(x, y) • dr = f (1, 0) - f (0, 0) = 7/2 - 0 = 7/2
• From Q back to the origin:
∫ F(x, y) • dr = f (0, 0) - f (3, 3) = 0 - 99/2 = -99/2
Then the total integral is 7/2 + 46 - 99/2 = 0, as expected.
