1/2x + 2/3 = 3/4Find the xX=??

Mathematics
1 answer:
Burka [1]3 years ago
3 0

Answer: x=\frac{1}{6}

Step-by-step explanation:

To find x, we want to isolate x.

\frac{1}{2}x+\frac{2}{3} =\frac{3}{4}           [subtract both sides by \frac{2}{3}]

\frac{1}{2} x=\frac{9}{12} -\frac{8}{12}        [subtract]

\frac{1}{2} x=\frac{1}{12}                [multiply both sides by 2]

x=\frac{2}{12} =\frac{1}{6}

Now, we know that x=\frac{1}{6}.

How much smaller is the sum of the first 1000 natural numbers than the sum of the first 1001 natural numbers?
aleksandr82 [10.1K]

ANSWER

1001

EXPLANATION

The sum of the first n - natural numbers is

S_n=  \frac{n}{2} (2a + d(n - 1))

The sum of the first 1000 terms is

S_{1000}=  \frac{1000}{2} (2(1) + 1(1000 - 1))

S_{1000}=500 (1001)

S_{1000}=500500

The sum of the first 1001 terms is

S_{1001}=  \frac{1001}{2} (2(1) + 1(1001 - 1))

S_{1001}= 1001 \times (501)

= 501501

The difference is

501501 - 500500= 1001

Consider a normal distribution curve where 90-th percentile is at 20 and the 25-th percentile is at 10. use this information to
ivann1987 [24]
The 25th percentile corresponds to z ≈ -0.67.
The 90th percentile corresponds to z ≈ 1.28.
So, you can write two equations in μ and σ as here:
.. μ -0.67σ = 10
.. μ +1.28σ = 20

The solution is
.. μ ≈ 13.45
.. σ ≈ 5.11
