look at the trapezium below, work out the size of angle
angle tuv
angle vwt
give your answer in degrees
Answer:
Step-by-step explanation:
The value of angle ADC is 157.4°
How do you find angle In a trapezium?
The sum of angles in a trapezoid-like other quadrilateral is 360°. So in a trapezoid ABCD, ∠A+∠B+∠C+∠D = 360°. Two angles on the same side are supplementary, that is the sum of the angles of two adjacent sides is equal to 180°. The length of the mid-segment is equal to 1/2 the sum of the bases.
Therefore angle A + angle D = 180
using trigonometry,
cos A = 12/13
A = cos^-1(0.923)
A = 22.63°
therefore angle D = 180-22.63
= 157.4° ( 1 dp)

Jamal performed an experiment flipping a coin. He did 10 trials and then his arm got tired. He recorded his results in the table. Based on the experimental probability, Jamal predicted that the number of times the coin lands heads up will always be greater than the number of times it lands tails up. What is the error in his prediction?
A 3-column table with 2 rows. Column 1 is labeled Coin with entries heads, tails. Column 2 is labeled Observed frequency with entries 8, 2. Column 3 is labeled Experimental probability with entries 0.80, 0.20.
He should have performed fewer trials before comparing them to the theoretical probability.
He did not need to perform the experiment to compare theoretical and experimental probabilities.
He should have subtracted the theoretical probability from the experimental probability.
He did not perform enough trials to compare the theoretical and experimental probabilities.
100 points
Answer: He did not perform enough trials to compare the theoretical and experimental probabilities.
Step-by-step explanation:
He only gave two entries for the experimental probability.He would need atleast four or three.

First you need to draw in a diagonal across the "floor" of the room connecting 2 vertices. You should draw the diagonal so that it's going in the same direction as the spider's thread; the diagonal is drawn in the wrong way if it intersects across the spider's thread.
Then you need to mark in the measures. The figures that are parallel to each other are congruent, so they have equal measures. For example, the rectangle that is parallel to the 6 by 8 one has the same measures as that one. Also, all of the walls of the room are rectangles. That means that the opposite sides of each rectangle have equal measures.
Because the diagonal divides the rectangle into 2 right triangles, you can then use the Pythagorean theorem to find the length of the diagonal that you drew in. (12 squared + 8 squared = length of the diagonal squared, and solving gives you the length of the diagonal as the square root of 208)
Finally, you can see that there is another right triangle formed with the diagonal that includes the spider's thread. With the length of the diagonal and the length of 6 ft, you can use the Pythagorean theorem to find the length of the spider's thread. (6 squared + the square root of 208 squared = length of the thread squared) The length of the spider's thread is the square root of 244, which is 15.6 ft rounded to the tenth's place.
Please help me out. Ik its late but whoevers up rn please help me out this is needed by 12pm tomorrow. Thank You!!
Answer:
B 30°
Step-by-step explanation:
come now.
the sum of all angles around one point on one side of a line is 180°.
why ?
because any line with a point can be seen as a diameter of a circle with that point as center.
and every side of the line represents then a half-circle.
and a half-circle stands for 360/2 = 180°.
so,
180 = (2x + 70) + (x - 10) = 2x + 70 + x - 10 = 3x + 60
120 = 3x
x = 40
2x + 70 = 2×40 + 70 = 80 + 70 = 150°
x - 10 = 40 - 10 = 30°
180 = Q + (2x + 70) = Q + 150
30° = Q

4th option
Step-by-step explanation:
Because the fourth option is the only option where the y-intercept is 15, which refers to the base price, and also 10x shows that every hour adds 10 dollars to the 15 dollar base price, and as the question says, it is higher than the 7.5 dollars an hour in the table above.

A standard car tire has a diameter of 18 inches. If you drive 2 miles to school, how many times does your car tire rotate during the drive? (1 mile = 5,280 ft)
Answer:
Step-by-step explanation:
1. Convert the 2 miles into ft. 2*5280=10560.
2. Convert the 18 inches to ft. 18/12=1.5ft
3. Divide. 10560/1.5=7040

32x+5x
Answer: 37x
Step-by-step explanation:
because both terms have an x after them, they are "like terms", so you can add the coefficients (numbers in front of x)
32+5=37
so your answer is 37x because you keep the term
ex. 5x+6y are different terms so you can't add them, 5 is in terms of x and 6 is in terms of y.

A car dealership has various combinations of vehicles in their car lot, all of which have an equally likely chance of being selected.
Use the list of options below to determine the probability of each vehicle being selected. The problem is based on independent events.
Answer:
Step-by-step explanation:
The probabilities of each of the following combination in question is 1/8, 1/6, 1/8, and 1/12 respectively.
The car dealership offers combinations of car parameters. The possible values of each car parameter are :
Vehicle = [Sedan, Suv, Truck]
Exterior color = [Red, Blue, Silver, Black]
Interior Material = [Leather, Cloth]
1. The probability of selecting a Silver Vehicle with a Cloth Interior is 1/8.
P(Silver, Cloth) = P(Exterior = Silver, Interior=Cloth)
= P(Exterior = Silver) * P(Interior=Cloth)
= (1/Total exterior options) * (1/Total interior options)
2. The probability of selecting an SUV or Truck with a Red or Black color and Cloth Interior is 1/6.
P(SUV|Truck, Red|Black, Cloth)
= P(Vehicle=Suv|Truck, Exterior = Red|Black, Interior=Cloth)
= P(Vehicle=Suv|Truck) * P(Exterior = Red|Black) * P(Interior=Cloth)
= (2/Total vehicle options) * (2/Total exterior options) * (1/Total interior options)
3. The probability of selecting a Sedan of a non-Red color and Cloth Interior is 1/8.
P(Sedan, !Red, Cloth)
= P(Vehicle=Sedan, Exterior != Red, Interior=Cloth)
= P(Vehicle=Sedan) * (1- P(Exterior = Red)) * P(Interior=Cloth)
4. The probability of selecting a Truck of a Blue or Black color and Leather Interior is 1/12.
P(Truck, Blue|Black, Leather)
= P(Vehicle=Truck, ExteriorBlue|Black, Interior=Leather)
= P(Vehicle=Truck) * P(Exterior = Blue|Black)) * P(Interior=Leather)

If Jason ran 1.8 miles and Josh ran
3,200 yards, who ran the farthest?
(1 mile = 5,280 feet)
Answer: Josh ran the farthest.
Step-by-step explanation:
1 mile = 5,280 feet
1.8 miles = 1.8 x 5,280 feet = 9,504 feet
1 yard = 3 feet
9,504 feet = 9,504 / 3 yards = 3,168 yards
So Jason ran 3,168 yards.
Since 3,200 yards is greater than 3,168 yards, Josh ran the farthest.
Answer:
Josh ran further
Step-by-step explanation:
I converted Josh's yards to miles.
[tex]\frac{3200yards}{1 }[/tex] · [tex]\frac{3 feet}{1 yard}[/tex] · [tex]\frac{1 mile}{5280feet}[/tex] cancel out the words that you see on the top and on the bottom
[tex]\frac{3200}{1}[/tex] · [tex]\frac{3}{1}[/tex] [tex]\frac{1mile}{5280}[/tex] Now simplify by multiplying
[tex]\frac{9600 miles}{5280}[/tex] = 1.8181... This is a repeating number
1.8181... is larger than 1.8

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
[tex]a^{2}[/tex] + [tex]28^{2}[/tex] = [tex]35^{2}[/tex]
[tex]a^{2}[/tex] + 784 = 1225

In which step does the first mistake appear
(23.8 / 2 + 12) + 14.5 / 2
step 1 (23.8 / 14) + 14.5 /
2 step 2 1.7 + 14.5 / 2
step 3 1.7 + 7.25
step 4 8.95
Answer:
The mistake appears in step 1 where 23.8 is divided by 14 instead of 2.
The correct first step should be: (23.8 / 2) + 12 + (14.5 / 2)
Hope this helps!
Answer:
A
Step-by-step explanation:
The error arises in the equation "(23.8 / 2 + 12)", where the division is incomplete. A slick fix is to rephrase it as "(23.8 / 2) + 12" to ensure accurate calculation, with the division taking precedence over addition, resulting in a cooler computation!
Suppose you borrow money for a year at a simple interest rate of 7.2%. You pay $86.40 in interest. How much have you borrowed?
Answer:
$1200
Step-by-step explanation:
You want to know the amount borrowed at 7.2% if the simple interest for one year is $86.40.
InterestThe interest formula is ...
I = Prt
where P is the amount borrowed, r is the interest rate, and t is the number of years.
ApplicationUsing the given values, we have ...
86.40 = P·0.072·1
P = 86.40/0.072 . . . . . . divide by the coefficient of P
P = 1200
You have borrowed $1200.
Answer: 1200
Step-by-step explanation: Linear equation. 7.2x = 100(86.40). then divide by 7.2 on each side. x=1200
