Answer:
6000
Step-by-step explanation:
25*16 = 400
400*15 = 6000
Answer:
a.. rs 7000
Because 15×1000=15000 it is SP when selling 1000units in the rate of Rs 15/unit& 8×1000=8000 this is cp when buying 1000 units in the rate of Rs 8/unit.
So,by formula of profit,
Rs (15000-8000)=Rs7000
Answer:
1496.52 Pa, 14.76 atm
Step-by-step explanation:
This question can be solved using ideal gas law
according to which
pv = nrt
where p is the pressure of gas
v is volume of gas
n is amount gas in moles
R is ideal gas constant whose value is 8.314 J/mol
T is absolute temperature of gas on Kelvin scale
______________________________
given
v = 5 liter
n = 3
T = 300 kelvin
R = 8.314 J/mol
Let the pressure be p
Substituting the above value in ideal gas law equation we have
p*5 = 3*8.314*300
p = 7482.6/5 = 1496.52 Pa
This pressure is in pascal while option is in atm
we know 1 Pascal is equal to 0.0000098692 atm
we know that 1 Atm = 101325 Pa
thus, 1496.52 is equal to 0.0000098692*1496.52 atm
1496.52 is equal to 14.76 atm
Answer:
- <u><em>A. Both numbers are statistics.</em></u>
Explanation:
The number 94.6 is an average measure from a <em>sample</em>. It is the mean of a sample.
The number 65.3 is the standar deviation of a sample.
Then, thus numbers are used to estimate the values of the population.
The true mean and the standard deviation of a population are constant numbers; many times unknown (specially when the population is too big). As ,those values are <em>parameters</em> of the population, regardless they are known or not.
When, they are not known, the statistician must estimate them. The statistician does it using samples (one or more). Such <em>estimated values are not parameter but statistics.</em>
Statistics are values for a sample and may (in general will) vary from sample to sample, while the parameters, which belong to the population are fixed values.
You would use the pythagorean theorem. a² +b² =c²
side² +side² = hypotenuse²
So for 1) 8² + 15² = c²
64+225=c²
289=c²
√c² = √289
c = 17
2. 7²+24² =c²
49+576= c²
c²=625
√c²= √625
c = 25
3. 5²+13²=c²
25+169=c²
c² = 194
√c² = √194
c = 13.93
4. 24² + 45² =c²
576 + 2025 =c²
c² = 2601
√c² = √2601
c = 51
5.
Plug each choice into the pythagorean theorem. a² +b² =c²
3²+4² = 5²
9+16= 25
25=25
6²+8²=10²
36+64=100
100=100
16²+63²=65²
256+3969=4225
4225=4225
8²+9²=10²
64+81=100
145=100 Since 145 does not equal 100 it is not a right triangle
