The missing figure is attached down
Answer:
ΔPAX ≈ ΔYAQ ⇒ proved down
PA × AQ = YA × AX ⇒ proved down
AQ = 7 cm
Step-by-step explanation:
In two triangles: if their corresponding angles have the same measures, then they are similar
In triangles ABC and XYZ, if m∠ABC = m∠XYZ, m∠BCA = m∠YZX, m∠CAB = m∠ZXYThen, ΔABC ≈ ΔXYZIf two triangles are similar, then their corresponding sides are proportion
If ΔABC ≈ Δ XYZ, then[tex]\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}[/tex] ⇒⇒⇒ Their sides are proportionIn our question:
From the attached figure
∵ YQ // PX
∴ m∠AYQ = m∠APX ⇒ corresponding angles
∴ m∠AQY = m∠AXP ⇒ corresponding angles
∵ ∠A is a common angle
∴ ΔPAX ≈ ΔYAQ ⇒ proved
∵ ΔPAX ≈ ΔYAQ
∴ Their corresponding sides are proportion
→ side PA is corresponding to side YA
→ side AX is corresponding to side AQ
→ side PX is corresponding to side YG
∴ [tex]\frac{PA}{YA}=\frac{AX}{AQ}=\frac{PX}{YQ}[/tex]
∵ [tex]\frac{PA}{YA}=\frac{AX}{AQ}[/tex]
→ By using cross multiplication
∴ PA × AQ = YA × AX ⇒ proved
∵ AX = 14 cm
∵ PA = 6 cm
∵ YA = 3 cm
→ Substitute these values in the relation above
∴ 6 × AQ = 3 × 14
∴ 6 AQ = 42
→ Divide both sides by 6
∴ AQ = 7 cm

Consider the equation 1.5x + 4.5y = 18.
Where does the graph intersect the x-axis?
Answer:
(12,0)
Step-by-step explanation:
We know that,
If the ordinate (y coordinate) is 0.. the point lies on the x axis
Hence,
[tex]Substituting\ y=0\\1.5x=18\\x=18/1.5\\x=180/15\\x=12[/tex]
Hence, the graph intersects the x axis at the point (12,0)

Answer:
X = 12
Step-by-step explanation:
Basically, just start with 11 and do all of the steps backwards, so multiply 11 by 5, which is 55, then add 2, 57. divide by 3, which is 19, then subtract 7, and you'll get the original number, 12.
Answer:
x = 12
Step-by-step explanation:
Following the steps in the flowchart
(1) Input the number x
x
(2) Add 7
x + 7
(3) Multiply by 3
3(x + 7)
= 3x + 21
(4) Subtract 2
3x + 21 - 2
= 3x + 19
(5) Divide by 5
[tex]\frac{3x+19}{5}[/tex]
(6) Output the number 11
[tex]\frac{3x+19}{5}[/tex] = 11 ( multiply both sides by 5 )
3x + 19 = 55 ( subtract 19 from both sides )
3x = 36 ( divide both sides by 3 )
x = 12

Choose 1 answer:

The value of a + b is given as follows:
B. 3.
How to define a linear function?The slope-intercept equation for a linear function is presented as follows:
y = mx + b
In which:
m is the slope, representing the rate of change.b is the intercept.Line 1 has a slope of 2, hence:
y = 2x + b
It contains the point (1,8), hence the intercept b is given as follows:
8 = 2 + b
b = 6.
Hence the line 1 is:
y = 2x + 6.
For the second line, we have that when x increases by 1, y decreases by 1, hence the slope m is given as follows:
m = -1.
Hence:
y = -x + b.
When x = 1, y = 2, hence the intercept b is given as follows:
2 = -1 + b
b = 3.
Hence the line 2 is:
y = -x + 3.
The x-coordinate of the intersection point, representing the value of a, is given as follows:
2x + 6 = -x + 3
3x = -3
x = -1 (a = -1).
The y-coordinate of the intersection point, representing the value of b, is given as follows:
y = -(-1) + 3
y = 4 (b = 4).
Hence the sum is given as follows:
-1 + 4 = 3.

The piston moves from the Top dead center as a result of a change * crank angle ratio of crank radius to connected length connected length crank radius the distance from TDC to the crank center equal to * a=crank radius b= connected length a*b a+b. the piston travel changed with * connected rod length crank angle R/L crank radius 2 points 2 points 2 points
The piston travel in an engine is influenced by the crank angle, crank radius, and connected rod length. The relationship between these variables is described by the formula a + b, where a represents the crank radius and b represents the connected rod length. The piston travel is directly related to the change in crank angle and is affected by the ratio of crank radius to connected rod length.
In an engine, the motion of the piston is driven by the crankshaft, which converts the rotational motion of the crank into linear motion of the piston. The distance traveled by the piston from the Top Dead Center (TDC) is influenced by various factors, including the crank angle, crank radius, and connected rod length.
The crank angle represents the angle through which the crankshaft rotates. As the crankshaft rotates, the piston moves up and down in the cylinder. The change in crank angle directly affects the piston travel.
The crank radius (a) is the distance from the center of the crankshaft to the point where the connecting rod is attached. The connected rod length (b) is the distance from the attachment point on the crank to the attachment point on the piston. The sum of the crank radius and the connected rod length, represented by a + b, determines the piston travel.
The ratio of crank radius to connected rod length also plays a role in the piston travel. This ratio affects the motion of the piston and determines the relationship between the crank angle and the linear displacement of the piston.
In summary, the piston travel in an engine is determined by the change in crank angle and is influenced by the ratio of crank radius to connected rod length. The formula a + b, where a represents the crank radius and b represents the connected rod length, describes the relationship between these variables. By understanding these factors, engineers can optimize the design and performance of internal combustion engines.

The weights of adult women are approximately normally distributed about a mean of 142 lbs. with a standard
deviation of 14 lbs. If Renee is at the 96 percentile in weight for adult women, then her weight, in lbs. is closest
to
Answer:
166. 5
Step-by-step explanation:
Given the following :
Mean weight (m) = 142 lbs
Standard deviation (sd) = 14 lbs
Renne = 96 percentile, what is Renne's weight
Using the equation :
Zscore = (score - mean) / standard deviation
96 percentile = 0.96 is equivalent to a Zscore of
1.75
Hence,
1.75 = (score - 142) / 14
14 * 1.75 = score - 142
24.5 = score - 142
24.5 + 142 = score
Score = 166.5

A survey of 300 students is selected randomly on a large university campus. They are asked if they use a laptop in class to take notes. Suppose that based on the survey, 105 of the 300 students responded "yes."
a. What is the value of the sample proportion?
b. What is the standard error of the sample proportion?
c. Construct an approximate 95% confidence interval for the true proportion.
In a survey of 300 randomly selected students on a university campus, 105 of them responded "yes" when asked if they use a laptop in class to take notes. The sample proportion of students using laptops is 0.35. The standard error of the sample proportion is approximately 0.0289. By constructing an approximate 95% confidence interval, we find that the true proportion of students using laptops in class falls between 0.293 and 0.407.
To calculate the sample proportion, the standard error of the sample proportion, and construct an approximate 95% confidence interval for the true proportion.
a. The sample proportion is the ratio of the number of students who responded "yes" to the total number of students surveyed. In this case, the sample proportion is 105/300 = 0.35.
b. The standard error of the sample proportion measures the variability of the sample proportion. It can be calculated using the formula:
SE(p) = sqrt((p * (1 - p)) / n),
where p is the sample proportion and n is the sample size. Plugging in the values, we get:
SE(p) = sqrt((0.35 * (1 - 0.35)) / 300) ≈ 0.0289.
c. To construct an approximate 95% confidence interval for the true proportion, we can use the formula:
CI = p ± z * SE(p),
where CI represents the confidence interval, p is the sample proportion, z is the critical value corresponding to the desired level of confidence (in this case, for 95% confidence, z ≈ 1.96), and SE(p) is the standard error of the sample proportion.
Plugging in the values, we have:
CI = 0.35 ± 1.96 * 0.0289,
which gives us the confidence interval (approximately) as 0.293 to 0.407.
