Answer:
Direction of travel.
Step-by-step explanation:
Given that two vehicles traveled 200 km in 3 hours ;
Distance apart after 3 hours = 400 km
A logical solution to this final distance between the two cars can be explained by their direction of travel.
Since the Cars both covered the same distance over the same period of time, the both cars must have started from a common point and traveled in opposite direction.
Meaning ;
Car 1 traveled 200 km in a certain direction
Car 2 traveled 200km in the opposite direction
Hence, distance between the cars will be :
Distance covered by car 1 + distance covered by car 2
200km + 200km = 400km
Ruchi covers 3.25 Kilometres in 50 minutes. How much distance will she cover in Metres in 94 minutes?
Answer:
Distance covered by Ruchi = 61.1 km
Step-by-step explanation:
Formula of the Speed is given by,
Speed = [tex]\frac{\text{Distance covered}}{\text{Time taken}}[/tex]
Since, Ruchi coves distance = 3.25 km
Time taken to cove this distance = 50 minutes
Therefore, speed of Ruchi = [tex]\frac{3.25}{50}[/tex]
= 0.65 km per minute
Therefore, distance covered by Ruchi in 94 minutes,
0.65 = [tex]\frac{\text{Distance covered}}{94}[/tex]
Distance covered = 0.65 × 94
= 61.1 km
Explain how you will evaluate 4[ 3(62+1)] - 63
Answer:
693
Step-by-step explanation:
You can simply apply BODMAS(Bracket of Division Multiplication Addition Subtraction)
Here, the brackets come first
62+1=63
63*3=189
189*4=756
756-63=693
Answer:
720
Step-by-step explanation:
First you do the things inside the parenthesis which is 62 + 1 = 63
Which gives you this -----> 4[ 3 x 63]-36
Then do the brackets (brackets are these btw "[ ]" )
After doing the brackets you should bet this 4 x 189 - 36
Then you do the multiplication -----> 756 - 36
756 - 36 = 720

Solve for X.
Then, solve for Y.
Finally, solve for Z.
Answer:
x = 29.5
y = 48.16
z = 34.05
Step-by-step explanation:
Sorry if the explanation is messy
answer
x=29.44
y=48.08
z=68
Step-by-step explanation:
opp/adj = tan(30)
17/x = tan(30)
x = 29.44
hyp^2 = x^2+y^2
hyp^2 = (29.44)^2 + (17)^2
hyp^2 = 867 + 289
hyp = 34
opp/hyp = Sin(45)
34/y = Sin(45)
y = 48.08
adj/hyp = Cos(45)
z/(48.08) = Cos(45)
z = 68
It is desired to estimate the average weight of a new born baby. The birth records of arandom sample of 60 babies' weights showed a mean of 7.0 lbs and standard deviation of 1.5 lbs.Construct a 95% confidence interval forμ.
Answer:
95% confidence interval for the mean
(6.61251, 7.38749)
Step-by-step explanation:
Step:-1
Given that a random sample 'n' = 60
Given that mean of the sample x⁻ = 7.0
Given that the standard deviation of the sample (S) = 1.5
Level of significance = 0.05
Degrees of freedom = n-1 = 60-1 = 59
t₍₀.₀₅ , ₙ₋₁₎ = 2.0010
Step(ii):-
95% confidence interval for the mean is determined by
[tex](x^{-} - t_{0.05,n-1} \frac{S.D}{\sqrt{n} } , x^{-} + t_{0.05 , n-1} \frac{S.D}{\sqrt{n} } )[/tex]
[tex]( 7.0 - 2.0010 \frac{1.5}{\sqrt{60} } , 7.0 + 2.0010 \frac{1.5}{\sqrt{60} } )[/tex]
(7.0 - 0.38749 , 7.0 + 0.38749)
(6.61251 , 7.38749)
Final answer:-
95% confidence interval for the mean
(6.61251 , 7.38749)

Answer:
a) 58.24 square centimeters
b) 5cm
Step-by-step explanation:
a) Area of a parallelogram
The formula for the Area of a parallelogram = Base × Height
Height : 5.2cm
Base : 11.2cm
Area = 5.2 cm × 11.2cm
= 58.24 square centimeters
b) Volume of a cuboid
The formula for the Volume of a cuboid = Length × Width × Height
7cm = Width
3cm = Length
y = Height
Volume = 105cm³
We are to find y
Hence,
105cm³ = 7cm × 3cm × y
y = 105cm³/7cm × 3cm
y = 5cm

En una tienda de ropa vas a comprarte una pantalones que están de 150 a 90 euros y una camiseta de 40 a 24 ¿ tienen el mismo porcentaje de rebaja ?
Respuesta:
Sí, tienen el mismo descuento del 40%
Explicación paso a paso:
Dado :
PANTALÓN :
Precio inicial = 150
Precio con descuento = 90
Porcentaje de descuento en el precio:
(150 - 90) / 150 * 100%
60/150 * 100%
0,4 * 100
= 40%
CAMISA:
Precio inicial = 40
Precio con descuento = 24
Porcentaje de descuento en el precio:
(40-24) / 150 * 100%
16/40 * 100%
0,4 * 100
= 40%
Sí, tienen el mismo descuento del 40%

At a certain middle school, there are 200 5th graders, 220 6th graders, 180 7th graders, and 150 8th graders. The Dean of Students chooses a scholar at random to help run Community Circle. What is the probability that a 7th grader is chosen?
Answer:
6/25
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
probability that a 7th grader is chosen = total number of 7th graders / total number of students
total number of 7th graders = 180
total number of students = 200 + 220 + 180 + 150 = 750
180 / 750
To transform to the simplest form. divide both the numerator and the denominator by 30
6 / 25
