A triangle has an area of 76 sq. in. The base is 20 in. what is the height?
Answer:
7.6 = h
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
76 = 1/2 *20 *h
76 = 10 h
Divide each side by 10
76/10 = 10h/10
7.6 = h
Answer:
7.6 inches
Step-by-step explanation:
The area of a triangle can be found using:
a=(b*h)/2
We know that the area is 76 in^2 and the base is 20 in. Substitute 76 in for a and 20 in for b.
76=(20*h)/2
Now we have to solve for h, by getting h by itself.
First, get rid of the denominator of 2 by multiplying both sides by 2
76*2=20*h/2*2
76*2=20*h
152=20*h
Next, divide both sides by 20, because 20 and h are being multiplied.
152/20=20*h/20
152/20=h
7.6=h
The height is 7.6 inches
Blackjack is a popular card game or cards are assigned various point values. Face cards and tens are the only cards worth 10 points. Each round begins with the player being dealt two cards. The table below is a partially completed probability distribution for the random variable Y, where Y is the number of 10 point cards a player gets at the beginning of a round. Find the missing probability in the table for P(0).
The probability of not drawing a 10-point card in the first two draws in a game of Blackjack, represented as P(0), is approximately 0.475 or 47.5%.
Explanation:The subject of this question is probability in the card game of Blackjack, specifically relating to the chance of drawing a 10-point card (all tens and face cards). To calculate the probability of not drawing any 10-point cards in the initial draw (2 cards), we need to determine the total number of 10-point cards and two-card combinations that do not involve any 10-point card.
A standard deck of 52 cards has 16 that are worth 10 points (four tens, four jacks, four queens, and four kings). The number of all possible two-card draws is '52 choose 2', or 1326 (calculated using combination formula).
The number of two-card combinations not involving any 10-point card, is equal to '36 choose 2', as there are 36 non-10-point cards in the deck (52 total minus 16 that are worth 10). This equals 630.
Therefore, the probability P(0), i.e., of not drawing any 10-point cards in the initial draw, is 630 / 1326 = 0.475 or 47.5%.

The missing probability in the table, representing the likelihood of drawing one 10 point card at the beginning of a Blackjack round is 0.475.
Explanation:Let's solve for P(Y = 0) given the probability distribution table for the random variable Y, where Y represents the number of 10-point cards a player gets at the beginning of a round:
Y 0 1 2
P(Y) ? 0.435 0.090
We know that the sum of all probabilities for all possible outcomes must equal 1. Therefore:
[tex]\[ P(Y = 0) + P(Y = 1) + P(Y = 2) = 1 \][/tex]
Substituting the known probabilities:
[tex]\[ P(Y = 0) + 0.435 + 0.090 = 1 \][/tex]
Now, solve for P(Y = 0):
[tex]\[ P(Y = 0) = 1 - 0.435 - 0.090 \][/tex]
[tex]\[ P(Y = 0) = 0.475 \][/tex]
So, after the calculation, P(Y = 0) equals 0.475.

25% sale
The jacket costs $76, and the price is marked down 25%.
Normally, you would pay for 100% of the price, but because it is marked down 25%, you are only paying 75% of the normal price.
Now, find the price of the jacket.
Multiply 75% and $76
75%*76
Convert 75% to a decimal by dividying by 100
75/100=0.75
0.75*76=57
The jacket costs $57 with the sale.
10% coupon
The jacket on sale costs $57. The coupon will take off another 10%.
Instead of paying for 100% of the jacket, you are paying for 90% with the coupon that takes 10% off.
Multiply 90% and $57
90%*57
Convert 90% to a decimal by dividing by 100
90/100=0.9

Step-by-step explanation:
2.5^2 = 6.25
6.25 * 4 = 25
Answer:
19.63 cm
Step-by-step explanation:
Because it can be heard from all directions, it takes the shape of a circle. Plus, it's 2.5 in all directions, so the lines are all equal. Therefore, 2.5 is the radius. They're asking for the area here, and the formula for area of a circle is A = PI*R^2. I'll use 3.14 to substitute for pi. Exponents first. 2.5^2 = 6.25. After that, we multiply. 3.14*6.25 = 19.625. We arrive at the answer. 19.625 square miles.

If the measure of angle 2 is (5x+14)degrees and angle 3 is (7x-14)degrees what is the measure of angle 1 in degrees
Answer: Measure of angle 1 is 13.84° .
Step-by-step explanation: Given angle 2 = (5x+14)°
angle 3 = (7x-14)°.
Let the angle 1 be x°,
As we know m∠1+m∠2+m∠3 = 180° (Angle sum property)
x°+(5x+14)+(7x-14) = 180°
x°+12x = 180°
13x = 180
x = 180/13 = 13.84°
∴Measure of angle 1 is 13.84°

4. Do you think a binary code can be transmitted by light, sound, or radio waves, or only by using an electrical current? Explain your answer.
Answer:
Yes, they came up with the telegraph, which transmits through radio waves. Binary code could probably also be transmitted in light, sound, or radio waves.
Binary code can be transmitted through light, sound, and radio waves, not just electrical current. These transmissions use AM, FM, and phase modulation, with light waves as the most efficient for high-speed data transfer.
Binary code can indeed be transmitted through various mediums besides just electrical current. This includes light, sound, and radio waves. Radio waves do indeed belong to the electromagnetic spectrum just like light waves do but with lower frequencies. Thus, a radio detects these electromagnetic waves, not light in the visual sense, and converts them into sound waves we can hear.
Light waves, unlike sound waves, do not need a physical medium to travel; they can move through a vacuum, transmitting information efficiently as electromagnetic waves. This is the principle behind fiber optic cables, which use pulses of light to transmit information encoded as binary code at high speeds. The rate at which information can be transmitted on an electromagnetic wave is proportional to its frequency, explaining why high-frequency laser transmissions in fiber optics can carry more conversations than lower-frequency electronic transmissions in wires.
George sold 18, 22, 26, 12, 25, 20, and 19 cars per month over the past seven months. He followed the steps below to determine the number of cars he needs to sell in the next month to have a mean number of sales per month of 24.
Step 1: Find the total cars needed to have a mean of 24: 24 times 7 = 168.
Step 2: Find the total cars sold: 18 + 22 + 26 + 12 + 25 + 20 + 19 = 142.
Step 3: Subtract the total cars sold from the total cars needed: 168 minus 142 = 26.
Step 4: State the answer: George needs to sell 26 cars next month.
Where did George make his first mistake?
Step 1
Step 2
Step 3
Step 4
George made his first mistake in Step 1 by calculating the mean for 7 months instead of 8. The correct calculation should be 24 times 8 to find the total number of cars he needs for an 8-month period.
The student has asked where George made his first mistake in determining how many cars he needs to sell to have a mean number of sales of 24 per month. Reviewing the steps he took, it is important to ensure the right number of periods is considered. In this case, if George is calculating the mean across 8 months rather than 7 months, as 7 months have passed and he needs the average after the next month (the 8th), he made his first mistake in Step 1 where he calculated 24 * 7 instead of 24 * 8. Therefore, the correct calculation should be 24 times 8 which equals to 192. This is the total number of cars he needs to have sold over the 8 months, to achieve a mean of 24 cars sold per month.

the diameter of a circle is 26 miles. what is the circle's circumference. Use 3.14 for pi
Answer:
It’s 530.66
Step-by-step explanation:
To find the circumference of a circle with a diameter of 26 miles, use the formula C = πd. Substitute the values and calculate the circumference as 81.64 miles.
The circumference of a circle can be calculated using the formula: C = πd, where d is the diameter of the circle. Given that the diameter is 26 miles and π is approximately 3.14, you can substitute these values into the formula to find the circumference.
Substitute the values: C = 3.14 x 26
Calculate the circumference: C = 81.64 miles. This calculation demonstrates how the circumference of a circle can be accurately computed using known values, providing essential information for various applications such as navigation, engineering, and geometric analysis.
