Two classmates, Aisha and Brandon, want to attend two school activities
over the coming weekend. They have one parking pass between them. The
probabilities that the classmates will attend each event are shown in the
table.
Aisha
Brandon
0.90
0.71
Probability of attending
the Saturday activity
Probability of attending
the Sunday activity
0.68
0.89
They decide to let the person more likely to attend both events have the
parking pass. Assuming that attendance at one activity is independent of
attendance at the other, who is more likely to attend both activities?
A. Aisha. She has a 0.61 probability of attending both activities.
B. Brandon. He has a 0.71 probability of attending both activities.
C. Brandon. He has a 0.63 probability of attending both activities.

Answer: The first one is  144 .   The second one is   C.

Step-by-step explanation:

Answer:

1) Full surface area = 156unit^2 this is correct.

lateral surface area = 144unit^2, this wasn't asked.

2) C = 528unit^2 is correct.

Lateral = 480unit^2 this wasnt asked.

Step-by-step explanation:

yes the next one is C 528

The formula for finding the surface area is the same for all right prisms and is: Surface area = 2B + hP. In this formula, B is the area of one of the bases, while h is the prism's height, and P is the perimeter of the base.

In effect;

step 1 = parallel sides indicate the bases of all triangular prism

step 2 = perimeter = 3+4+5 = 12

step 3 = LA = P x H = P x Length which is lateral height

              LA = 12 x 12 = 144

step 4 = SA = 1/2 b x h (height of triangle) +LA

             SA = 1/2 4 x 3      + LA

             SA = 2 x 3 = 6 = 1 base + LA   (+base)

             SA = 6+6 = 12 + 144  = 156 = 2b+LA

IF you remember LA is perimeter x length of prism but label L as H then use little h for triangle h. You can remember.

Answer:

Step-by-step explanation:

Solving quadratics is easy. With no coefficient to the x^2, we can go right to finding factors. We want two numbers that multiply to -21, and add to 4. Our numbers are 7, and -3. Now, we move the numbers around to be (x-3) and (x+7). We know that these both equal 0, so we can do basic algebra to solve for x. We can subtract 7 to the other side to just get x, and add 3 over because it is subtracted by x. This leaves us with our answers:

x = -7, x = 3

Answer: y = 2x + 2

Step-by-step explanation:

To find the slope of a line perpendicular to another line, you take the slope of the other line and flip it (find the negative reciprocal) and make it negative.

In this case, -1/2 would become 2. 2 is now the slope of the line perpendicular to the other line.

Since the line passes through (1, 4), we can plug the point in - the line will be

y = 2x + 2.

Answer:

y=2x+2.

Step-by-step explanation:

Honestly the perpendicular flipping didn't make sense, but somehow google thought so, so ill leave it at this, if you need more help, just message me.

Answer:

M

Step-by-step explanation:

Similar angles would be the same location.

H is the 3rd letter in the first set, so it would be similar to the 3rd letter in the second set.

H is similar to M

Answer:

D. (-x+5)^2/9+(y-4)^2/4=1    (I assume there was a mistype)

Step-by-step explanation:

The first step is isolating the sine and cosine functions.

x=5-3cos(t)

x + 3cos(t) = 5

3cos(t) = 5 - x

cos(t) = (5 - x)/3

y=4+2sin(t)

y - 4 = 2sin(t)

(y - 4)/2 = sin(t)

Then, square at both sides of the equal sign

cos²(t) = (5 - x)²/3² = (5 - x)²/9

sin²(t) = (y - 4)²/2² = (y - 4)²/4

Recall the trigonometric identity and replace.

cos²(t) + sin²(t) = 1

(5 - x)²/9 + (y - 4)²/4 = 1

Answer:

f(-3) = 13

Step-by-step explanation:

f(x) = x² + 4        Substitute -3 for x

f(-3) = (-3)² + 4   Simplify the exponent

f(-3) = 9 + 4        Add

f(-3) = 13

Answer:

C or [tex]y=\frac{1}{4}^{x}[/tex]

Step-by-step explanation:

when x is 0 y is 1 and every positive number to the zeroth power is 1

so It can be A or C

but the value of y goes down when x goes up so its exponential decay or less than 1 so 1/4<1 So

C or [tex]y=\frac{1}{4}^{x}[/tex]

Answer:

x=-4,y=5

Step-by-step explanation:

Answer:

B (-4,5)

Step-by-step explanation:

x-3y=-19

2x+y=-3

this is how I'll start it off, I'll multiple the bottom equation by 3 to have the y-value become the reciprocal (opposite) of the top equation.

now it's:

x-3y=-19

6x+3y=-9

now add/subtract

7x=-28

divide 7 from both sides

x=-4

now plug -4 into the equations to get y

-4-3y=-19

add 4 to both sides to get rid of -4

-3y=-15

divide -3 on both sides

y=5

now to double check, do the other equation

2(-4)+y=-3

-8+y=-3

add 8 to both sides to get rid of -8

y=5

now to check the answer, plug in x=-4 and y=5 into the equations

-4-3(5)=-19

-4-15=-19

2(-4)+5=-3

-8+5=-3

Explanation:

If you have repeated x values, then you wont have a function. For example, the points (1,5) and (1,6) mean we don't have a function since the input x = 1 leads to multiple outputs y = 5 and y = 6 simultaneously. For a function to be possible, we must have any input lead to exactly one output only.

What we do is set the x coordinates (k^2 and 3k) equal to each other and solve for k

k^2 = 3k

k^2-3k = 0

k(k-3) = 0 .... factoring

k = 0 or k-3 = 0 .... zero product property

k = 0 or k = 3

If k = 0, then (k^2,5) becomes (0,5). Also, (3k,6) becomes (0,6). The two points (0,5) and (0,6) mean the graph fails the vertical line test.

Similarly, if k = 3, then (k^2,5) becomes (9,5) and (3k,6) = (9,6). Another vertical line test failure happens here to show we don't have a function.
