Step-by-step explanation:
Find the area of the figure shown.
Answer:220
Step-by-step explanation:
LET X BE THE LENGTH OF RECTANGLE AND FOR UPPER PORTION OF DIA GRAM BASE OF RIGHT ANGLE TRIANGLE SO X=20
LET Y BE WIDTH OF RECTANGLE SO Y=8
LET P BE THE PERPENDICULAR OF THE RIGHT TRIANGLE SO P=6
THEN
AREA OF RECTANGLE=LENGTH*WIDTH
SO AREA OF RECTANGLE BECOMES=(20)(8)=160
AND AREA OF RIGHT ANGLE TRIANGLE BECOMES=1/2(BASE*(PERPENDICULAR)
SO =1/2(20)(6)=60
SO THE TOTAL AREA OF THE DIAGRAM=AREA OF RIGHT ANGLE TRIANGLE+AREA OF RECTANGLE=160+60=220

If a city with a population of 100,000 doubles in size every 28 years, what will the population
be 56 years from now?
Answer:
400,000
Step-by-step explanation:
Calculate the doubling time period-
Doubling time period(t)=
doubling time period(t)= 2
Calculate the new population using the doubling time formula below where t is the number of doubling periods:
Population = Initial Population * [tex]2^{t}[/tex]
Population = 100000 * [tex]2^{2}[/tex]
Population = 100000 * 4

Answer:
Step-by-step explanation:
17x + 14 + 4x -2 = 21x + 12
21x + 12 = 180
-12 -12
21x = 168
x = 8 degrees
[tex]\boxed{\large{\bold{\green{ANSWER~:) }}}}[/tex]
Here,
The two lines l and m are parallel,
cut by a transversat line t
So The two angles are supplementary each other.
we know that,The sum of two supplementary angles are 180°
According to the question,(17x+14)°+(4x-2)°=180°
17x+14°+4x-2°=180°
17x+4x+14°-2°=180°
21x+12°=180°
21x=180°-12°
21x=168°
x=168°/21
x=8°
Therefore,The value of x is 8°
Neutering dogs is a common surgical practice. The mean time to recover from the general anesthetic used is 26 hours. A veterinarian believes that since changing to a new anesthetic, the mean recovery time is shorter than before. From a random sample of 40 surgeries with the new anesthetic, she finds the mean recovery time was 25 hours with a standard deviation of 2.5 hours. What is the p-value for her hypothesis test
Answer:
0.005719
Step-by-step explanation:
H0 : μ = 26
H1 : μ < 26
Given that:
Population mean, μ = 26
Sample mean, xbar = 25
Sample standard deviation, s = 2.5
Sample size, n = 40
The test statistic :
(xbar - μ) / s/sqrt(n)
Test statistic :
(25 - 26) / 2.5/sqrt(40)
-1 / 0.3952847
Test statistic = - 2.5298
Using a Pvalue calculator from Z test statistic:
Pvalue = 0.005719

Gavin is subdividing land into two plots, where one plot is in the shape of a square and the other plot is in the shape of a rectangle. The square plot of land has a side length of 6x3 feet, and the rectangular plot of land has a length of 3x5 feet and a width of 7x2 feet. Use the properties of exponents to determine the expression that represents the area for each plot of land. Then analyze which plot of land has a larger area if x is 3.

Step-by-step explanation:
Storage Space of Shed = Volume of Shed.
Volume of Shed = Volume of Rectangular level
+ Volume of Triangular roof
Volume of Rectangular Level =
Length x Width x Height
=
[tex]12 \times 6 \times 8 \\ = 576 {ft}^{3} [/tex]
Volume of Triangular Roof =
Area of Triangular side x Length
=
[tex] \frac{1}{2} \times base \times height \times length \\ = \frac{1}{2} \times 6 \times 4 \times 12 \\ = \frac{1}{2} \times 288 \\ = 144 {ft}^{3} [/tex]
Volume of Shed = 576 + 144
=
[tex]720 {ft}^{3} [/tex]

An incoming college student took her college’s placement exams in French and mathematics. In French, she scored 85 and in math 80. The overall results for both exams are approximately normal. The French mean score was 72 with a standard deviation of 12, while the mean math score was 70, with a standard deviation of 7.8. On which exam did she do better compare with the other incoming college students? Compute the z-scores (round to 2 decimal places) and the percentiles (round to the nearest whole) for each exam to support your answer.
Answer:
Following are the responses to the given question:
Step-by-step explanation:
[tex]French \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Mathematics\\\\X= 85\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ X= 80\\\\\mu=72\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \mu =70\\\\\sigma=12 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \sigma= 7.8\\\\[/tex]
Formula:
[tex]\bold{Z-Score=\frac{x-\mu}{\sigma}}\\\\French \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Mathematics\\\\Z=\frac{85-72}{12} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Z=\frac{80-70}{7.8}\\\\=1.0833 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ =1.2820\\\\[/tex]
In the french exam Z value is 1.0833 and in the maths exam Z value is 1.2820 that's why we can say that in maths exam, she does better than french exam.

Answer:
12 possible roots
Step-by-step explanation:
we can use the rational zeros theorem which says that in order to find the possible roots for a polynomial we need to divide the factors of the constant by the factors of the coefficient of the leading term
which in this case is:
±(1, 2, 3, 4, 6, 12)/(1)
±1, 2, 3, 4, 6, 12
so we have 12 possible roots

Step-by-step explanation:
Find the distance between the points (3, -8) and (8,4).
Answer:
13
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
Hello There!
We can calculate the distance between two points using the distance formula
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
where the x and y values are derived from the coordinates in which you are trying to find the distance between
The points we need to find the distance between is (3,-8) and (8,4)
So we plug the x values and y values into the formula
[tex]d=\sqrt{(8-3)^2+(4-(-8)^2} \\8-3=5\\4-(-8)=12\\d=\sqrt{5^2+12^2} \\5^2=25\\12^2=144\\144+25=169\\\sqrt{169} =13[/tex]
so we can conclude that the distance between the two points is 13 units
