question is in the picture above lol (help pls)

The probability that this person is a graduate student is 0.3833.

From the recent census

40% of its students mainly used Ma- cintosh computers.

At the time of the census, 67% of the school's students were undergraduates.

In the census, 23% of the respondents were graduate students who said that they used PCs as their primary computers.

We have to find the probability that this person is graduate student.

Let A represent the event that student uses Mac.

So P(A)=40%=0.4, P(A')=60%=0.6

Then let B be the event that randomly chosen student is undergraduate·

So, P(B) = 67%=0.67, P(B')= 33%=0.33

Further, 23% of respondents were graduate. Students who said they used PCs as their Primary Computers

So P(B'∩A')=23%=0.23

If we select a student at random from among those who were part of the Census and learn that student mainly uses PC, then probability that this person is a graduate student is:

P(B'|A') = P(B'∩A')/P(A')

P(B'|A') = 0.23/0.6

P(B'|A') = 0.3833

Hence, the probability that this person is a graduate student is 0.3833.

Answer:

h = -3y + 2x

Step-by-step explanation:

Add 4x to both sides of the equation.

2h = −6y + 4x

Divide each term in 2h = −6y + 4x by 2 and simplify.

Divide each term in 2h = −6y + 4x by 2.

2h/2 = -6y/2 + 4x/2

Simplify the left side.

h = −6y/2 + 4x/2

Simplify the right side.
Simplify each term.
Cancel the common factor of −6 and 2.

h = -3y+2(2x)/2

Cancel the common factors.
Factor 2 out of 2.

h = -3y+2(2x)/2(1)
Cancel the common factor

h = -3y+2(2x)/2(1)
Rewrite the expression
h = -3y + 2x/1

Divide 2x by 1.
h = -3y + 2x

hopefully its right LOLZ

We can conclude that there is no measurable effect of immersing them in water or dropping them. Thus, we cannot conclude that the treatment has any significant effect.

To answer whether there appears to be any measurable effect of immersing the devices in water or dropping them, we have to compare the average scores of each group before and after submerging them in water or dropping them.

The null and alternative hypotheses are stated as follows:

Null Hypothesis H0:

µ1 = µ2 = µ3

Alternative Hypothesis Ha:

µ1 ≠ µ2 ≠ µ3

The level of significance is α = 0.05.

ANOVA table helps us to calculate the test statistic.

The calculated F-value of 1.56 is less than the critical F-value of 3.05 at the 0.05 level of significance.

Since the calculated F-value is less than the critical F-value, we fail to reject the null hypothesis.There is no significant difference in the scores between the groups.

The equation that can be used to find the length of the hypotenuse of a right triangle is the Pythagorean theorem, which states that the sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse.

In the given triangle with side lengths 63, 16, and x, the length of the hypotenuse is represented by x. Thus, we can apply the Pythagorean theorem to find the value of x.

Using the Pythagorean theorem, we get:

x^2 = 63^2 + 16^2

Simplifying the equation, we get:

x^2 = 3969 + 256

x^2 = 4225

Taking the square root of both sides, we get:

x = 65

Therefore, the length of the hypotenuse of the right triangle is 65.

Answer:

P'Q' ⇔ 8 cm

A'B' ⇔ 6 cm

M'N' ⇔ 12 cm

Step-by-step explanation:

A dilation with a scale factor of 4 is applied to the three line segments PQ, AB and MN.

The length of PQ is given as: 2 cm.

The length of line segment AB is given as: 1.5 cm

The length of line segment MN is given as: 3 cm.

Now as there is a dilation with a scale factor of 4 to all the line segments this means that the resulting image will have length 4 times the length of these line segments.

PQ → P'Q'

⇒ Length of P'Q'= 8 cm.   ( since 4×2=8)

AB → A'B'

⇒ Length of A'B'= 6 cm.   ( since 1.5×4=6)

MN → M'N'

⇒ Length of M'N'= 12 cm.   ( since 4×3=12)

Hence,

P'Q' ⇔ 8 cm

A'B' ⇔ 6 cm

M'N' ⇔ 12 cm

As no points are shown so only steps can be provided to solve

So if A(x,y) is dilated by scale factor 4 then 4 is multiplied with A(x,y)

So new coordinates are (4x,4y)

So

if length of segment was x then after dilation new length is 4x

The homogeneous solution is: y_h = c1e^(2x) + c2e^(3x), the particular solution is: y_p = (-1/10)e^(-2x) + (1/8)sin(2x) - (3/40)cos(2x) and The characteristic equation is: r^2 + 2r + 4 = 0

To find the general solutions of the given differential equations using the D-operator method, we can first find the homogeneous solution and then the particular solution.
The general solution is the sum of the homogeneous and particular solutions.

(D^2 - 5D + 6)y = e^(-2x) + sin(2x)

First, let's find the homogeneous solution by solving the associated homogeneous equation:

(D^2 - 5D + 6)y = 0

The characteristic equation is:

r^2 - 5r + 6 = 0

Factoring the characteristic equation, we get:

(r - 2)(r - 3) = 0

This gives us two distinct roots:

r = 2 and

r = 3.

Therefore, the homogeneous solution is:

y_h = c1e^(2x) + c2e^(3x)

Next, let's find the particular solution. We assume a particular solution of the form:

y_p = Ae^(-2x) + Bsin(2x) + Ccos(2x)

Taking the derivatives of y_p, we have:

y'_p = -2Ae^(-2x) + 2Bcos(2x) - 2Csin(2x)

y''_p = 4Ae^(-2x) - 4Bsin(2x) - 4Ccos(2x)

Plugging these derivatives into the differential equation, we get:

(4A - 4Bsin(2x) - 4Ccos(2x)) - 5(-2Ae^(-2x) + 2Bcos(2x) - 2Csin(2x)) + 6(Ae^(-2x) + Bsin(2x) + Ccos(2x)) = e^(-2x) + sin(2x)

Simplifying and matching like terms, we get:

(-2A + 2B - 2C)e^(-2x) + (8A + 4B - 4C)cos(2x) + (8C + 2B + 4A)sin(2x) = e^(-2x) + sin(2x)

To solve this system of equations, we equate the coefficients of each term:

-2A + 2B - 2C = 1

8A + 4B - 4C = 0

8C + 2B + 4A = 1

Solving this system of equations, we find:

A = -1/10

B = 1/8

C = -3/40

Therefore, the particular solution is:

y_p = (-1/10)e^(-2x) + (1/8)sin(2x) - (3/40)cos(2x)

Finally, the general solution is the sum of the homogeneous and particular solutions:

y = y_h + y_p

y = c1e^(2x) + c2e^(3x) - (1/10)e^(-2x) + (1/8)sin(2x) - (3/40)cos(2x)

(D^2 + 2D + 4)y = e^(2x)sin(2x)

Similarly, let's find the homogeneous solution first:

(D^2 + 2D + 4)y = 0

The characteristic equation is:

r^2 + 2r + 4 = 0

When any two straight lines intersect each other, then four angles are formed. The angles that are directly opposite to each other are known as opposite angles. They are also called vertical angles or vertically opposite angles.

Now, from the image attached, we see that the two given angles are opposite angles and as such they are congruent. Thus, we have;

4x + 2 = 7x - 25

Which phrase best captures the average rate of change in the price of solar energy between 1977 and 1987?

Which equation best captures the yearly average increase rate of solar prices between 1977 and 1987?

This discussion aims to help students remember what average rate of change for a function means and how it is computed. Select students to explain what each expression's value in this context means. For instance, the cost difference for a solar cell between 1977 and 1987 is represented by the formula p(10)- p(0), whereas the percent change between 1977 and 1987 may be calculated as p(10)/p(0). The fact that the real phrase for the average rate of change, p(10)-p(0)/10-0=-7.55, reveals that the price declined by -$7.55 on average per year since the expression considers the whole difference in price between the 1977 and 1987 divided by the total number of years that passed.
