The shape of the sampling distribution of the proportions is "approximately normal" is the correct answer.
What is the sampling distribution of proportion?"The sampling distribution of proportion measures the proportion of success, i.e. a chance of occurrence of certain events, by dividing the number of successes i.e. chances by the sample size n".
For the given situation,
Total number of random samples = 1000
A map website claims to be available of time = 99.995%
⇒ [tex]0.99[/tex]
Let us assume the website's claim is accurate.
Sample proportions closest to 0.6 would be most common, and sample proportions far from 0.6 in either direction would be progressively less likely. In other words, the shape of the distribution of sample proportion should bulge in the middle and taper at the ends: it should be somewhat normal.
Hence we can conclude that the shape of the sampling distribution of the proportions is "approximately normal" is the correct answer.

the measure of the seven angles in a pentagon measure 87, 105, 135, and 92. what is the measurement of the last angle
Answer:
121
Step-by-step explanation:
If you add them all up, 87+105+135+92= 419
the pentagon is equal to 540 degrees so minus 540 by 419
then you get 121

Answer:
25 (with assumptions)
Step-by-step explanation:
ASSUMING ES=SD and FT=TG, then the difference between EF and ST is the same as the difference between ST and DG. Since ST - EF = 19 - 13 = 6, then DG - ST = 6 or DG - 19 = 6, add 19 to both sides and DG = 25

which of the following quadratic will have a maximum value at x=3
(A) y=x^2-6x+19
(B) y=-4x^2+24x-21
(C) y=-2x^2+20x-49
(D) y=2x^2-3x+7
The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.
The maximum and minimum values of a function:
The maximum and minimum values are the highest and lowest values that a function can reach over a particular domain.
For example, in a quadratic function, the maximum or minimum value is the highest or lowest point on the graph, respectively.
If a function has a maximum value, it means that the function reaches its highest point at a certain value of x.
On the other hand, if a function has a minimum value, it means that the function reaches its lowest point at a certain value of x.
Here we have
(A) y = x²-6x +19
At x = 3
y = (3)² - 6(3) + 19
= 9 - 18 + 19 = 10
(B) y = -4x²+24x -21
At x = 3
y = -4 (3)² + 24(3) - 21
= - 4(9) + 72 - 21
= 15
(C) y= -2x² +20x -49
At x = 3
y = - 2 (3)² + 20(3) - 49
= - 18 + 60 - 49
= - 7
(D) y = 2x² -3x +7
At x = 3
y = 2(3)³ - 3(3) + 7
= 18 - 9 + 7
= 16
Therefore,
The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.

A rectangle has side lengths of x+1 and 1. What is an expression for the area of the rectangle?
These are the choices...
3
x + 1
x + 2
2x + 3
Thank You!!!
Answer:
x+1 SQUARE units
Step-by-step explanation:
Area of a rectangle is height times width or you could just say the length on one side times the length of a side right next to it.
If the rectangle is x+1 units long and 1 unit high, then the answer is (x+1) x 1 = x +1 because anything times 1 is always just what you started with.
If Earth's total mass is 6 x 10^24 kg, what proportion of this is lost every year?
Step-by-step explanation:
This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.
Find Sin D and sin E! Write the answer as a fraction and as a decimal. Round to four decimal places, if necessary! Please help me!
Answer:
sine D = 0.9459
sine E = 0.3243
Step-by-step explanation:
Mathematically, sine is the ratio of the opposite to the hypotenuse
The hypotenuse is the longest side and we have it as 37 in the diagram given
the opposite to angle E is 12
So the sine of E = 12/37 = 0.3243
For D , its opposite is 35
The sine of D = 35/37
sine of D = 0.9459

what is 3/4b>15 solution
The solution set of the given inequality is {b| b > 20}.
How to solve the inequality?Here we have the inequality (3/4)b > 15 and we want to solve it. To do so, we just need to isolate the variable b.
And to do it, we can work with this like we would do with any equation, we can just multipy both sides by (4/3) so we get:
(4/3)*(3/4)*b > 15*(4/3)
b > 20
Then the solution set can be written as {b| b > 20}
That is the set of all values larger than 20.

Answer:
y = 2/3x + 4
Step-by-step explanation:
Slope-intercept form of a line:
y = mx + bwhere m = slope and b = y-interceptTo find the equation of a line, we need two points that the line passes through.
We can use the x-intercept and y-intercept of the line: (-6,0) and (0,4), respectively.
Find the slope of the line using these two points:
Slope formula: [tex]\displaystyle \bf \frac{y_2-y_1}{x_2-x_1}[/tex]Plug the two points into the formula.
[tex]\displaystyle \frac{4-0}{0-(-6)}[/tex]Subtract and simplify this fraction.
[tex]\displaystyle \frac{4}{6} =\frac{2}{3}[/tex]The slope of this line is m = 2/3.
Now we can look at the graph to determine the y-intercept of this line; the line intersects the y-axis at (0,4) so the constant b = 4.
We can use the slope, m, and the y-intercept, b, and substitute these values into the slope-intercept form of a line.
y = 2/3x + 4The equation of the line is y = 2/3x + 4.
Answer:
y = 2/3x + 4
