Use Table A to find the proportion of observations from a standard Normal distribution that satisfies each of the following statements. Give your answers to four decimal places.
a) z < -0.67=
b) z > -0.67=
c) z < 1.46=
d) -0.67 < z < 1.46=
a) The proportion of observations, P(z < -0.67) = 0.2514.
b) The proportion of observations, P(z > -0.67) = 0.7486.
c) The proportion of observations, P(z < 1.46) = 0.9279.
d) The proportion of observations, P(-0.67< z < 1.46) = 0.6765.
A z-table, or standard normal table, helps to reveals what percentage of values fall below a certain z-score in a normal distribution. We have a standard normal table present above .
a) P( z < -0.67 )
Split -0.67 such as (-0.6 + 0.07 ) and look -0.6 in first column and 0.07 in first row then look cross value. So, P( z < -0.67 )
= 0.2514
b) P( z > - 0.67 ) = 1 - P( z < -0.67 )
From part (a ) , P( z < -0.67 ) = 0.2514
So, P( z > - 0.67 ) = 1 - 0.2514 = 0.7486
=> P( z > - 0.67 ) = 0.7486
c ) P( z < 1.46 ) = 1 - P( z < -1.46 )
Using Table, P( z < -1.46 ) is,
=> P( z < -1.46 ) = 0.0721
So, P( z < 1.46 ) = 1 - 0.0721 = 0.9279
=> P( z < 1.46 ) = 0.9279
d) P(-0.67 < z < 1.46 ) = P( z < 1.46) - P( z < -0.67 ) from part( a) , P( z < -0.67 ) = 0.2514
and from par (c) , P( z < 1.46 ) = 0.9279
So, P(-0.67 < z < 1.46 ) = 0.9279 - 0.2514
= 0.6765
=> P(-0.67 < z < 1.46 ) = 0.6765
Hence, all the required proportion are determined.

What is the unit price?The meaning of unit price is a price quoted in terms of so much per agreed or standard unit of product or service
Given that, a woman bought 1.8 kg of chicken and 1.6 kg of meat. The chicken cost $5.40 and the meat cost $6.40,
We need to find, if she had bought 2.4 kg of chicken and 2 kg of meat, how much would she have had to pay,
To find the same, we will first find the unit price of each,
Unit price = total price / total quantity
Since, 1.8 kg of chicken costs $5.40,
Therefore, 1 kg will cost = 5.40 / 1.8 = $3
Similarly,
If 1.6 kg of meat costs $6.40,
Therefore, 1 kg will cost = 6.40 / 1.6 = $4
Now, to find the cost of 2.4 kg of chicken and 2 kg of meat, we will multiply the unit prices to the required quantities,
Therefore,
2.4 kg of chicken will cost = 2.4 x 3 = $7.2
2 kg of meat will cost = 2 x 4 = $8
In total, she had to pay = 8+7.2 = $15.2
Hence, the amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Figure is shown in image.
Now, By definition of vertically opposite angle,
⇒ (y + 23)° = 63°
Solve for y;
⇒ y + 23 = 63
Subtract 23 both side,
⇒ y + 23 - 23 = 63 - 23
⇒ y = 40
And, By definition of supplementary angles, we get;
⇒ (2x - 17)° + 63° = 180°
Solve for x;
⇒ 2x - 17 + 63 = 180
⇒ 2x + 46 = 180
⇒ 2x + 46 - 46 = 180 - 46
⇒ 2x = 134

The distance between two points in three-dimensional space is a measure of the separation between the two points. In this case, the two points are the center of a sphere and a point that the sphere passes through.
To find the distance, we can use the distance formula in three dimensions, which is an extension of the distance formula in two dimensions. The distance formula is:
d = √((x1 - x2)^2 + (y1 - y2)^2 + (z1 - z2)^2)
where (x1, y1, z1) is the center of the sphere and (x2, y2, z2) is the point that the sphere passes through. The square root of the sum of the squares of the differences between the corresponding coordinates gives the distance between the two points.
In this problem, the center of the sphere is not given, so it is not possible to calculate the distance between the sphere and the point. The center of the sphere is a crucial piece of information needed to solve this problem.

find the numerical value of each expression. (round your answers to five decimal places.) (a) cosh(7)
The numerical value of cosh(7) is 25.78543.
The hyperbolic cosine function, cosh(x), is the inverse of the hyperbolic sine function, sinh(x). It is defined as the sum of the series cosh(x) = 1 + x²/2! + x⁴/4! + x⁶/6! + …, where x is any real number and n! is the factorial of n.
To find the numerical value of cosh(7), we need to evaluate the series at x = 7. To do this, we start by calculating the first two terms of the series, 1 and 7²/2!. The first term is 1, and the second term is 7²/2! = 49/2 = 24.5. Then we add them together to get the result cosh(7) = 25.5.
To get a more accurate result, we can add more terms to the series. For instance, by adding the third term, 7⁴/4!, we get cosh(7) = 25.5 + 585/24 = 25.70833. We can continue this process to get an even more accurate result.
After adding the sixth term, 7⁶/6!, we get cosh(7) = 25.70833 + 90090/720 = 25.78542.
Finally, we round the result to five decimal places to get cosh(7) = 25.78542 ≈ 25.78543.

What an initial value problem?An initial value problem is a differential equation in which the initial value of the function is given.
How to solve the initial value problem?Now we have the initial value problem
y' = (xy + y²)/x² , y(1) = 3.
We notice that it is a homogeneous differential equation.
What is a homogeneous differential equation?A homogeneous differential equation is a differential equation in which the powers of x and y are the same.
So, we proceed to solve the equation as folows.
Let y = vx.
So,
y/x = v and
dy/dx = xdv/dx + v
We now substitute these into the differential equation, we have that
y' = (xy + y²)/x²
dy/dx = (xy/x² + y²/x²
xdv/dx + v = y/x + (y/x)²
xdv/dx + v = v + v²
xdv/dx = v²
So using the method of separation of variables, we have
dv/v² = dx/x
Thus Integrating both sides, we have
∫dv/v² = ∫dx/x
-v⁻¹ = ㏑x + C
-1/v = ㏑x + C
We now substitute v = y/x into the equation, we have
- 1/y/x = ㏑x + C
-x/y = ㏑x + C
So, making y subject of the formula, we have
y = -x/(㏑x + C)
Since y(1) = 3, we have
3 = -1/(㏑1 + C)
3 = -1/(0 + C)
3 = -1/C
C = -1/3
So, y = -x/(㏑x + (-1/3))
y = -x/(㏑x - 1/3)
y = -x/(3㏑x - 1)/3
y = -3x/(3㏑x - 1)
So, the solution is y = -3x/(3㏑x - 1)

He recorded drawing a yellow marble 6 times,
Thus, the number of yellow marbles = 12 *6/25
the number of yellow marbles = 2.88 or 3 approx
He recorded drawing a blue marble 4 times,
Thus, the number of blue marbles = 12 *4/25
the number of blue marbles = 1.92 or 2 approx
He recorded drawing and a green marble 6 times.
Thus, the number of green marbles = 12 *6/25
the number of green marbles = 2.88 or 3 approx,

What is the decimal equivalent of the binary number 111010?
Answer:
23
Step-by-step explanation:
You have 6 numbers
So starting at 2^0, we write out 6 of those to get a benchmark. Well also solve them for now. To the left, we put your numbers, which are 111010
1: 2^0 = 1
1: 2^1 = 2
1: 2^2 = 4
0: 2^3 = 8
1: 2^4 = 16
0: 2^5 = 32
^ Everywhere there's a one, we use the number, everywhere there's a 0, we throw that out. Theres a 1 next to the first, second, third, and fifth numbers. Taking those numbers, we add them
1 + 2 + 4 + 16
Which equals 23, your decimal equivalent
