If a fair coin is tossed 6 times, what is the probability, rounded to the nearest thousandth, of getting at least 3 heads?
ANSWER IS 0.656
Answer:
Step-by-step explanation:
For each outcome there are
s!/(n!(s-n)!) combinations
where s is the number of selections and n is the number of specific outcomes
The probability of any specific outcome for 6 tosses of a coin is (1/2)^6
[(1/2)^6]*[(6!/6!)+(6!/(5!)+(6!/(4! 2!)+(6!/(3! 3!)]
(1/2)^6*(1+6+15+20)
42(1/2)^6
42(1/64)
42/64
21/32 which is 0.65625
0.656 (rounded to nearest thousandth)

The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 140 centimeters in 35 seconds. What is the time in seconds the toy robot moves when the total distance is 70 centimeters?
Answer:
17.5 seconds
Step-by-step explanation:
140 cm/35 sec (find unit rate)
4 cm/ 1 second
[tex]\frac{4}{1} = \frac{70}{x}[/tex] (divide 70 by 4)
70/4=17.5
[tex]\frac{4}{1} = \frac{70}{17.5}[/tex]
D Melissa takes the 10 30 from Christchurch. How long does she wait in Wellington? Hour minutes
Answer:
1:45 hours
Step-by-step explanation:
Given
See attachment for missing part of the question
Required
How long she waits in Wellington
From the question:
She takes the 10 30 from Christchurch
So:
[tex]Christchurch\ Depart = 10\ 30[/tex]
This implies that:
She has to wait until Wellington arrives at 11 15
So:
[tex]Wellington\ Arrives= 11\ 15[/tex]
So, the wait time is:
[tex]Wait\ time = Wellington\ Arrives - Christchurch\ depart[/tex]
[tex]Wait\ time = 11: 15 - 10: 30[/tex]
[tex]Wait\ time = 1:45\ hr[/tex]

Step-by-step explanation:
Find the volume of the cylinder find volume of a cylinder with the same radius and double the height what is the volume of the cylinder
Answer:
1004.8^3
Step-by-step explanation:
to find the volume you must first get the area of the base
3.14 x 8 squared or 8^2 which will equal 200.96
then you multiply the base times height
200.96^2 x 5 = 1004.8 cubed or 1004.8^3
also be careful you don't multiply 200.96 twice because it is squared (;

since -15/16 is a negative number, we can add both sides by 15/16 or subtract both sides by -15/16. Either way works.
p = 1/8 + 15/16
Use common denominator, which is 16:
p = 1(2)/8(2) + 15/16
p = 2/16 + 15/16
p = 17/16
17/16 is an improper fraction. If you want to use a mixed number for your answer, then:
17/16 becomes 1 1/16 (one and one-sixteenth, with 1 being a whole number and 1/16 being a fraction)
Answer: 17/16 or 1 1/16Hi can you help? It’s kinda easy I’m just confused

A jeweler has several boxes of earrings to ship to a store. Each box is a cube with a side length of 5 centimeters. The jeweler packs the boxes in a shipping container. The filled container has 4 layers, where each layer contains 7 rows and 10 columns of boxes. What is the volume of the shipping container?
Answer: [tex]35,000\ cm^3[/tex]
Step-by-step explanation:
Given
The earring box has a volume of [tex]a=5\ cm[/tex]
It is packed and loaded in the container which has 4 layers and each layer has 7 rows and 10 columns
We can say that each layer can hold [tex]7\times 10=70\ \text{boxes}[/tex]
The volume of each earring box is
[tex]V_o=a^3=5^3\\V_o=125\ cm^3[/tex]
Four layers can hold [tex]4\times 70=280\ \text{boxes}[/tex]
the container can hold 280 boxes
[tex]\therefore \text{Volume of container is}\ V=280V_o\\\Rightarrow V=280\times 125=35000\ cm^3[/tex]
M∠QPS=88 ∘ m, angle, Q, P, S, equals, 88, degrees \qquad m \angle RPS = 5x + 34^\circm∠RPS=5x+34 ∘ m, angle, R, P, S, equals, 5, x, plus, 34, degrees \qquad m \angle QPR = 8x + 15^\circm∠QPR=8x+15 ∘
The correct question is:
[tex]\angle QPS=88[/tex]
[tex]\angle RPS=5x+34[/tex]
[tex]\angle QPR=8x+15[/tex].
Find ∠QPR.
Answer:
[tex]\angle QPR = 39[/tex]
Step-by-step explanation:
From the attached figure:
[tex]QPS = QPR + RPS[/tex]
This gives:
[tex]88 = 8x + 15 + 5x + 34[/tex]
Collect like terms
[tex]88 - 15 - 34 = 8x + 5x[/tex]
[tex]39 = 13x[/tex]
Divide both sides by 13
[tex]3 = x[/tex]
[tex]x =3[/tex]
Substitute [tex]x =3[/tex] in [tex]\angle QPR=8x+15[/tex]
[tex]\angle QPR = 8 * 3 + 15[/tex]
[tex]\angle QPR = 24 + 15[/tex]
[tex]\angle QPR = 39[/tex]

Step-by-step explanation:
if you are looking for the altitude, then we have and adjacent side and hyp. so COS 52=y/36
.616=y/36
22.164=y
Tan (28)= 22.164/x
.5317x=22.164
x=41.69

Ella buys eggs and apples at the store.
She pays a total of $44.35.
She pays a total of $2.95 for the eggs.
She buys 6 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of apples costs.
Answer:
6.9
Step-by-step explanation:
The total payment was 44.35 and Ella bought 6 bags of apples and eggs
eggs cost 2.95 so apples cost 44.35-2.95=41.4
lets call bags "x"
so
6x=41.4 (price)
divide both by 6
x=6.9

Answer:
x = 14√3
y = 7√3
Step-by-step explanation:
By applying sine rule in the given triangle,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{21}{x}[/tex]
x = [tex]\frac{42}{\sqrt{3}}[/tex]
x = 14√3
By applying cosine rule in the given triangle,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{y}{x}[/tex]
[tex]\frac{1}{2}=\frac{y}{14\sqrt{3}}[/tex]
y = 7√3
