[ad_1]

Answer:

3 hours.          

Step-by-step explanation:

Let x be the time taken by shoe repairman to repair one pair.

We have been given that his assistant, who takes twice as long to repair a pair of shoes. So time taken by his assistant to repair one pair of shoes would be 2x.

The number of pair of shoes repaired by repairman in one hour would be frac{1}{x}.

The number of pair of shoes repaired by assistant in one hour would be frac{1}{2x}.

We have been given that together they can fix 16 pairs of shoes in an eight-hour day. We can represent this information in an equation as:

frac{1}{x}+frac{1}{2x}=frac{8}{16}

frac{1}{x}+frac{1}{2x}=frac{1}{2}

Let us have a common denominator.

frac{2*1}{2*x}+frac{1}{2x}=frac{1}{2}

frac{2}{2x}+frac{1}{2x}=frac{1}{2}

frac{2+1}{2x}=frac{1}{2}

frac{3}{2x}=frac{1}{2}  

Upon cross multiplying our equation we will get,

2x*1=3*2

2x=3*2

frac{2x}{2}=frac{3*2}{2}

x=3

Therefore, it take 3 hours for the repairman to fix one pair of shoes by himself.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

Answer:

A. y=sec x

D. y= csc x

Step-by-step explanation:

We have that,

Range of the functions is the set of all real numbers greater than or equal to 1 or less than or equal to -1.

As, we know that,

Range of the functions, y = tanx and y = cotx is (-infty,infty) i.e. the set of all real numbers.

So, options B and C are discarded.

Since, csc x=frac{1}{sin x} and sec x=frac{1}{cos x}.

Thus, their range will be greater than the the range of y = sinx and y = cosx.

Now, as it is known that the range of the functions  y = sinx and y = cosx is [-1,1].

Then, the range of y=sec x and y= csc x is the set of all real numbers greater than or equal to 1 or less than or equal to -1.

Hence, options A and D are correct.

First we calculate for the total number of possibilities
(permutation) to select 4 disks from the container:

Total number of possibilities = 10 * 9 * 8 * 7

Total number of possibilities = 5040


Now let us find the 4 disks that will result in a range of 7.

Range = highest number – lowest number

The pair of highest and lowest number that will result in
range of 7 is: (1 & 8), (2 & 9), (3 & 10)

 

As a basis of calculation, let us use the pair 1 & 8.

There are four possible ways to select 1 and three for 8.

Arrangements of maximum and minimum pair = 4 * 3

Arrangements of maximum and minimum pair=12

Now we need to calculate for the remaining 2 disk. There
are 6 numbers between 1 & 8. The total possibilities for selecting 2 disk
from the remaining 6 is:

Possibilities of selecting 2 disk from remaining 6 = 6 *
5

Possibilities of selecting 2 disk from remaining 6 = 30

Therefore, the total possibility to get a range of 7 from
a pair of 1 & 8 is:

Total possibility for a pair = 12 * 30

Total possibility for a pair = 360

 

Since there are a total of three pairs (1 & 8), (2
& 9), (3 & 10):

Total possibilities of the 3 pairs = 360 * 3

Total possibilities of the 3 pairs = 1080

 

Therefore:

Probability = Total possibilities of the 3 pairs / Total
number of possibilities

Probability
= 1080 / 5040 = 3 / 14                      (FINAL

Step-by-step explanation:

Step 1

Find the lateral area

we know that

The formula to calculate the lateral area is equal to

LA=Ph

where

P is the perimeter of the base of the prism

h is the height of the prism

In this problem we have

P=2+9+9.23=20.23 m

h=47 m

substitute in the formula

LA=20.23*47=950.81 m^{2}

LA=951 m^{2}

Step 2

Find the surface area

we know that

The formula to calculate the surface area is equal to

SA=2B+Ph

where

B is the area of the base of the prism

P is the perimeter of the base of the prism

h is the height of the prism

In this problem we have

B=9*2/2=9 m^{2}

P=2+9+9.23=20.23 m

h=47 m

substitute in the formula

SA=2(9)+20.23*47=968.81 m^{2}

SA=969 m^{2}

Answer : The number of moles of water formed can be, 128 moles

Solution : Given,

Moles of hydrogen gas = 138 moles

Moles of oxygen gas = 64 moles

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction will be,

2H_2+O_2rightarrow 2H_2O

From the balanced reaction we conclude that,

As, 2 moles of hydrogen gas react with 1 mole of oxygen  gas

So, 138 moles of hydrogen gas react with frac{138}{2}=69 moles of oxygen  gas

But the given moles of oxygen gas is 64 moles.

That means oxygen gas is a limiting reagent and hydrogen gas is an excess reagent.

Now we have to calculate the moles of water.

From the reaction we conclude that,

As, 2 moles of oxygen react to give 1 mole of water

So, 64 moles of oxygen react to give 64times 2=128 moles of water

Therefore, the number of moles of water formed can be, 128 moles

The standard deviation σ is the square root of the variance:σ=V(X)−−−−−√=E(X2)−(E(X)2−−−−−−−−−−−−−√)where E(X)is the expected value of X. By definition,E(X)=∑x∈Dxp(x)where D is the values X may take (in this case D={0,1,2,3,4,5})and p(x)=P(X=x)is the probability that X equals x.Then,E(X)==0⋅p(0)+1⋅p(1)+2⋅p(2)+3⋅p(3)+4⋅p(4)+5⋅p(5)2.15.

a golf ball travels a distance of 600 feet as measured along the ground and reaches an altitude of 200 feet. If the origin represents the tee and the ball travels along a parabolic path that opens downward, find an equation for the path of the golf ball. …?

Answer:

y=1.32x-0.0022x^{2}

Step-by-step explanation:

Let the standard equation of parabola be y=ax^{2}+bx+c ……. (1)

Let y be the altitude of the ball and x be the distance traveled by the ball.

Now by putting the points one by one, we get the required equation.

first point = (0,0)

golf ball travels a distance of 600 feet  along the ground. Therefore point = (600,0)

At altitude of 200, it travels the distance of 300 feet(mid point) = (300,200)

By putting y=0 and x=0 in (1),

we get c=0,

By putting y=0 and x=600 we get

0 = 360000a+600b …………..(2)

By putting y=200 and x=300, we get

200=90000a+300b …………….(3)

Solving (2) and(3) we get, a=-0.0022 and b = 1.32

So the required equation is :

y= =0.0022x^{2}+1.32x
