Answer:
12/13
Step-by-step explanation:
The probability of not drawing an ace is =
1 minus the probability of drawing an ace.
there are 4 aces in a deck
hence the probability of not drawing an ace =
1 - [tex]\frac{4}{52}[/tex]
= 48/52 = 12/13
The required probability of not drawing an ace would be 12/13.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
You draw a card from a standard deck of 52 playing cards.
The probability of not drawing an ace is P(E)
There are 4 aces in a deck
So the number of favorable outcomes n(E)= 4
And the total number of outcomes n(S) = 52
Thus, the probability of drawing an ace = n(E)/n(S) = 4 / 52
The probability of not drawing an ace will be:
⇒ P(E) = 1 - n(E)/n(S)
⇒ P(E) = 1 - 4 / 52
⇒ P(E) = 48/52
⇒ P(E) = 12/13
Therefore, the required probability of not drawing an ace would be 12/13.

Solve for x
x/5 + 1 = 7
Steps:
Step 1: Simplify both sides of the equation.
1 /5x+1=7
Step 2: Subtract 1 from both sides.
1/5x+1−1=7−1
1/5x=6
Step 3: Multiply both sides by 5.
5*(1/5x)=(5)*(6)
Description:
Since we are solving for x first steps is to Simplify both sides of the equation. Then subtract 1 from both sides. After that multiply both sides by 5 and you will get your answer. The correct answer for this question is x=30.
Answer: x=30
Please mark brainliest
Hope this helps.
The value of x from the given equation is 30.
The given equation is x/5 +1=7.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, x/5 +1=7
Transpose 1 to other side of the equation, we get
x/5 =7-1
x/5 = 6
Transpose 5 to other side of the equation, we get
x = 6×5
x = 30
Therefore, the value of x from the given equation is 30.

What is the measure of ∠R?
Answer:
∠ R ≈ 36.9°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos R = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus

Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.
Answer:
-23.18, -0.82
Step-by-step explanation:
h² + 24h + 19 = 0h²+2h*12+12²-125=0(h+12)²-√125²=0(h+12+11.18)(h+12-11.18)=0(h+23.18)(h+0.82)=0h+23.18=0 ⇒ h= -23.18h+0.82=0 ⇒ h= -0.82Answer:
-23.18, -.82
Step-by-step explanation:
h^2 + 24h + 19 = 0
Subtract 19 from each side
h^2 +24h = -19
Take the coefficient of h
24
Divide by 2
24/2 =12
Square it
12^2 =144
Add this to both sides
h^2 +24h+144 = -19+144
(h+12)^2 =125
Take the square root of each side
sqrt((h+12)^2) =±sqrt(125)
h+12 = ±sqrt(125)
Subtract 12 from each side
h+12-12 = -12 ±sqrt(125)
h =-12 ±sqrt(125)
h = -12 - sqrt(125) = -23.18033989
h = -12 + sqrt(125) = -.819660113
To the nearest hundredth
-23.18, -.82

At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least 16 tickets. The system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
r + f ≥ 16
4r + 2f ≤ 40What is the maximum number of ride tickets she can buy?
Answer:
The maximum number of ride tickets is 4
Step-by-step explanation:
r = number of ride tickets
f = number of food tickets
r + f ≥ 16
4r + 2f ≤ 40
Using these as equations
f = 16 -r
Using this in the second equation
4r+ 2 (16 -r) = 40
4r +32 -2r = 40
2r +32 = 40
2r = 8
r = 4

Find the sum of each infinite geometric series, if it exists
The first series diverges because each successive term is getting multiplied by -3, so the common ratio is larger than 1 in magnitude.
Assuming the second series is
3 - 3/2 + 3/4 - 3/8 + ...
then it converges because the common ratio between terms is -1/2, which is less than 1 in magnitude.
To find the value of the sum, let S denote the n-th partial sum, i.e. the sum of the first n terms in the series:
S = 3 - 3/2 + 3/4 - 3/8 + ... + 3(-1/2)^(n - 2) + 3(-1/2)^(n - 1)
Multiply both sides by -1/2:
(-1/2) S = -3/2 + 3/4 - 3/8 + 3/16 - ... + 3(-1/2)^(n - 1) + 3(-1/2)^n
When we subtract S and (-1/2) S, we see all the middle terms canceling, and we can solve for S:
S - (-1/2) S = 3 - 3(-1/2)^n
S/2 = 3[1 - (-1/2)^n]
S = 6[1 - (-1/2)^n]
As n gets larger, the (-1/2)^n term will converge to 0, leaving us with
lim (n -> infinity) S = 6
so that the series converges to 6.

In 20 words or fewer, describe the kind of relationship you see between the x-coordinates of the midpoint and the endpoint not at the origin
Answer:
Remember, if we have two points (x1, y1) and (x2, y2) we can draw a segment that connects those two points, and we can define the midpoint of those two endpoints as:
( (x1 + x2)/2. ((y1 + y2)/2)
if we are only in the x-axis, then y = 0.
in this situation one of the endpoints seems to be at the origin, and the other is a given value (X´. 0)
Then, the midpoint is:
( (Xp + 0)/2, 0) = (X´/2, 0)
Then, the relationship is:
"the value at the midpoint is half ot the value at the endpoint that is not at the origin"

2. A man walks at a rate of 1.25 / . Find the time he takes to walk 3.75 km.
Answer:
(1) The formula to calculate simple interest (SI), with principal = 600$, annual rate = 4% = 0.04, and time = 9 months is:
SI = principal x rate x time
= 600 x (0.04/12) x 9
= 18$

Answer:
24.49 units
Step-by-step explanation:
The circumference of the circle is 153.86 units.
The circumference of a circle is given as:
C = 2 * pi * r
where r = radius of the circle
Therefore:
r = C / (2 * pi)
=> r = 153.86 / (2* pi) = 24.49 units
