Answer:
0.014
Step-by-step explanation:
The probability that the Islanders will win at least 6 out of seven is the probability of them winning exactly 6 games, P(X=6), added to the probability of them winning all seven games, P(X=7).
This problem can be treated as a binomial probability model with probability of success p = 0.38 in each of n = 7 games.
[tex]P(X=x) = \frac{n!}{(n-x)!x!}*p^ x*(1-p)^{(n-x)}[/tex]
Thus:
[tex]P(X=6) = 7*0.38^6*0.62\\P(X=6) =0.01307\\P(X=7) = 0.38^7\\P(X=7) =0.00114[/tex]
The probability is:
[tex]P(X\geq 6) = 0.01307+0.00114\\P(X\geq 6) = 0.014[/tex]
The probability that the Islanders will win at least six out of seven games in a series against the Rangers is 0.014.
Solve for d.
–4(–3d − 3) = 6d
d =
Answer:
d = -2
Step-by-step explanation:
→Distribute the -4 to (-3d - 3)
-4(-3d - 3) = 6d
12d + 12 = 6d
→Subtract 6d from both sides:
6d + 12 = 0
→Subtract 12 from both sides:
6d = -12
→Divide both sides by 6:
d = -2
Answer:
[tex] \boxed{d = -2} [/tex]
Step-by-step explanation:
[tex]= > - 4( - 3d - 3) = 6d \\ \\ = >( ( - 4) \times ( - 3d)) - ( - 4 \times 3) = - 6d \\ \\ = > 12d + 12 = 6d \\ \\ = > 12d - 6d + 12 = 0 \\ \\ = > 6d + 12 = 0 \\ \\ = > 6d = - 12 \\ \\ = > d = - \frac{12}{6} \\ \\ = > d = - 2[/tex]

In Triangle A B C, what is the value of x? Triangle A B C. Angle A is 112 degrees. Exterior angle to angle B is 2 x degrees and the exterior angle to angle C is (2 x + 12) degrees.
Answer:
70°
Step-by-step explanation:
∠A =112°,
Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)
Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x
∠A + ∠B + ∠C = 180 (sum o angles in a triangle)
112 + 180 - 2x + 168 - 2x = 180
460 - 4x = 180
4x = 460 - 180 = 280
x = 280/4 = 70
x = 70°
Answer:
70º

what is the answer for this equation 8k - 62 = 2 plz answer this correctly
Answer:
k = 8
Step-by-step explanation:
You are solving for the variable, k. Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS =
Parenthesis
Exponents
Multiplications
Division
Addition
Subtraction
First, add 62 from both sides:
8k - 62 = 2
8k - 62 (+62) = 2 (+62)
8k = 2 + 62
8k = 64
Next, divide 8 from both sides:
(8k)/8 = (64)/8
k = 64/8
k = 8
8 is your answer for k.

Answer:
The equation are:
1) h + s = 20
2) 4h = 1s
Step-by-step explanation:
Number of hats Elliott made = h
Number of scarfs Elliott made = s
total number of items Elliott made = 20
h + s = 20 ..[1]
1 hat uses 0.2 kilograms of yarn
1 hat = 0.2 kg of yarn
Then h hats will use = 0.2h kg of yarn
1 scarf uses 0.1 kilograms of yarn
1 scarf= 0.1 kg of yarn
Then s scarfs will use = 0.1s kg of yarn
She wants to twice as much as yarn for scarves for hats:
2 × (0.2h kg of yarn) = 0.1s kg of yarn
0.4h = 0.1s
4h = 1s...[2]
The equation are:
1) h + s = 20
2) 4h = 1s
Answer:C
0.1s=2•0.2h
H+S=30

Angle b measures 60 what is the measure of the angle that is complementary to angle b ?
Answer:
30°
Step-by-step explanation:
Complementary is they add up to 90°
90° - 60° = 30°
Answer:
30 degrees
Step-by-step explanation:
Complementary angles add up to 90 degrees. Thus, 60 and (complementary angle) = 90 degrees. Thus, the angle that is complementary to 60 degrees is 30 degrees.
) Dara invests $800 at 12.5% per annum compound
interest compounded half- yearly .What in his amount of
interest at the end of the first year?
answer: $1,012.50
Step-by-step explanation:
12.5 ÷ 100 = 0.125
0.125 × 800 = 100
800 + 100= 900 ( half-yearly interest)
0.125 × 900 = 112.5
900 + 112.5 = $1,012.50 ( end of first year interest)
Please answer this math question !! Thank u !! 20 POINTS AND BRAINLIEST!!
Answer:
infinite solutions
Step-by-step explanation:
Given the 2 equations
y = 6x - 3 → (1)
12x - 2y - 6 = 0 → (2)
Substitute y = 6x - 3 into (2)
12x - 2(6x - 3) - 6 = 0 ← distribute and simplify left side
12x - 12x + 6 - 6 = 0
0 = 0
This solution 0 = 0 indicates that any value of x is a solution
Thus there are an infinite number of solutions to the system

Jenny is going to tile her kitchen floor. She has taken out all the furniture and appliances. Below is the floor
plan of her kitchen.
2.5m
1.5m
14m
Jenny wants to know if she has got enough money to buy the tiles.
The tiles are sold in packs, which cover 3m
Jenny has a discount card which gives her 25% off any marked price at the DIY shop.
The tiles are marked at £14.40
Jenny has £100 to spend on the tiles.
How much extra does Jenny need to buy the tiles?
Give your answer in pence.
Answer:
Jenny needs £8 extra to buy the tiles.
Step-by-step explanation:
Jenny's kitchen floor is in the form of trapezoid.
Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
[tex]=\frac{1}{2}(2.5+1.5)14[/tex]
= 28 meter²
One pack of tiles covers the area = 3 meter²
She needs the number of packs of tiles = [tex]\frac{\text{total area }}{\text{area covered by one pack of tile}}[/tex]
[tex]=\frac{28}{3}[/tex]
= 9.33
Therefore, she has to purchase 10 packs of tiles.
Since the price of one pack of tiles = £14.40
Price of 10 packs of tiles = 14.40 × 10
= £144
Price after using discount card of 25% = 144 -(25% of 144)
= 144 - (0.25 × 144)
= 144 - 36
= £108
Jenny has £100, so she needs £8 extra to buy the tiles.
The price of a rare collection car has increased exponentially
over the past few years with a rate of increase estimated at 5% per year.
At the start of 2015 the value of the car was estimated at £265000.
Estimate the value of the car at the start of 2010.
Round your answer to 3 significant figures.
Answer: £208,000
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original price
r = increase rate (decimal form)
t= years (2015-2010 =5 years)
A = price after t years
Replacing with the values given:
265,000 = p (1+ 0.05)^5
Solving for p
265,000 = p (1.05)^5
265,000 = p (1.05)^5
265,000/ (1.05)^5 =p
p = £207,634. =208,000 (rounded)

In the triangle below, what is the length of the side opposite the 60° angle?
Answer:
C. 3√3
Step-by-step explanation:
Remember your 30-60-90 triangle rules.
They give you 3 as a side in the 30-60-90. That side length 3 will be your x. The side opposite of it is x√3. Simply plug in 3 as it is x and you should get 3√3 as your answer.
Answer:
C
Step-by-step explanation:
In all 30 60 90 triangles, the side opposite the 60 degree angle will be the short leg times [tex]\sqrt{3}[/tex]
So, the length of that side in this triangle will be 3[tex]\sqrt{3}[/tex]

If x=1+√2, evaluate x³+1/x³.
Answer:
18
Step-by-step explanation:
So we start solving like:
x+1x=3
(x+1x)3=33
x3+3.x2.1x+3.x.1x2+1x3=27
(x3+1x3)+3.x2.1x+3.x.1x2=27
x3+1x3+(3x+3x)=27
x3+1x3+3(x+1x)=27
x3+1x3+3×3=27
x3+1x3+9=27
x3+1x3=18
Therefore the answer is 18
Teresa is 25 years old, and she makes $30,000 per year. If Teresa were to die,
how much would the beneficiaries of her life insurance policy receive if they
can get by on 75% of her income?
Answer:
They would receive $22,500 which is 75% of her income
Step-by-step explanation:
Here, we want to know how much the beneficiaries of a life insurance scheme would receive if their principal die.
From the question, we are told that they have the right to claim 75% of her income
From the question also, we were told that what she earns per annum is $30,000
Now, since they have the right to claim 75%, the amount they can claim out of the said income will be;
75/100 * $30,000 = $22,500
Answer:225,000

How much money must be deposited to T
earn $200.00 in simple interest in 6 months at an annual
rate of 5.5%?
Can someone help me please?!
Answer:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 200(1 + (0.055 × 0.5)) = 205.5
A = $205.50
Step-by-step explanation:
If C is the midpoint of AB and AB = 20, what is AC?
Answer:
AC = 10
Step-by-step explanation:
AC+ BC =AB
If C is the midpoint then AC = BC
AC + AC = 20
2 AC = 20
Divide by 2
2AC /2 = 20/2
AC = 10
Answer:
AC=10
Step-by-step explanation:
If a-------c-------b and AB=20 and C is the midpoint, then half of 20 would be 10.
A circle is centered at Q(1,-5) and has a radius of 5. Where does the point Y(4,-1) lie?
Answer:
Point Y (4, -1) lies on the circle.
Step-by-step explanation:
Distance = √[(x2-x1)² + (y2 - y1)²] = √[(4-1)² + (-1-(-5))²] = √[3² + 4²]= √25 = 5
Point Y (4, -1) lies on the circle, because the distance from the center to this point equals radius of the circle.
Answer:
On the circle
