The average temperature during the winter in the Arctic tundra i -34C which is also 93.2 degrees Fahrenheit

The difference between the freezing point of water and its boiling point at normal atmospheric pressure is divided into exactly 100 equal parts to determine the temperature in degrees Celsius (degrees). Water has a freezing point set at 0° and a boiling point set at 100°.

Therefore, a 100°C difference is precisely equivalent to a 180°F difference. As a result, each degree in Celsius is equivalent to 1.8 degrees Fahrenheit.

The 34 Celsius to Fahrenheit formula is a linear function:

[°F] = ([34] x 9 ⁄ 5) + 32.

Therefore, we get:

34 C to F = 93.2 °F

34 °C in °F = 93.2 Fahrenheit

34 C in F = 93.2 degrees Fahrenheit

The cost of 250 bricks, delivered to a worksite, is $170. The cost of 400 bricks delivered is $245 and the cost to have 320 bricks will delivered $217.6 .

The cost of 250 bricks, delivered to a worksite, is $170.

So , we can calculate the single brick cost need to divide 170/250=0.68

Single brick cost is 0.68

The cost of 400 bricks delivered is $245.  In this case a single brick cost is 0.6125

The answers is different from the first answer we can calculate  320  brick cost 320×0.68=217.6

The following equation is used to calculate the Cost Per Brick. To calculate the cost per brick, divide the total cost of the bricks by the number of bricks.

Answer:

x = 45/2 or 22.5

Step-by-step explanation:

Since we are given CDE ~ KLM, we know that C is similar to K, D is similar to L, and E is similar to M. The problem asks to find DE, so by comparison, it is known that DE is similar to LM.

From the two triangles, KM is similar to CE, and we can see that the ratio between the two is 8:15. We are given LM, which is 12, so we can find x using this equation to compare the smaller triangle to the bigger one:

KM/CE = LM/DE

Plug in your given values:

8/15 = 12/x

Find x:

The probability that a randomly chosen unsatisfactory screen came from Philips is approximately 0.4444.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Let's call the probability that a screen came from Philips "P".

know that 55% of the screens came from Corning Inc. and the rest came from Philips, so:

P = 1 - 0.55 = 0.45

We also know that the probability of getting an unsatisfactory screen from Corning Inc. is 1%, while the probability of getting an unsatisfactory screen from Philips is 4%:

P(unsatisfactory | Corning Inc.) = 0.01

P(unsatisfactory | Philips) = 0.04

Using Bayes' theorem, the probability that a randomly chosen unsatisfactory screen came from Philips can be calculated as:

P(Philips | unsatisfactory) = P(unsatisfactory | Philips) * P(Philips) / [P(unsatisfactory | Philips) * P(Philips) + P(unsatisfactory | Corning Inc.) * P(Corning Inc.)]

Substituting the values we have:

P(Philips | unsatisfactory) = 0.04 * 0.45 / [0.04 * 0.45 + 0.01 * 0.55] = 0.444444... or approximately 0.4444

Therefore, the probability that a randomly chosen unsatisfactory screen came from Philips is approximately 0.4444.

The probability that a randomly chosen unsatisfactory screen came from Philips is 46.48%.

Let's call P(Philips) the probability that a randomly chosen screen came from Philips, and P(Unsatisfactory | Philips) the probability that a screen is unsatisfactory given that it came from Philips. Then we can use Bayes' theorem to find P(Philips | Unsatisfactory), the probability that a screen came from Philips given that it is unsatisfactory.

Bayes' theorem states:

P(A | B) = P(B | A) * P(A) / P(B)

where A and B are events, P(A | B) is the conditional probability of A given B, P(B | A) is the conditional probability of B given A, P(A) is the probability of A, and P(B) is the probability of B.

In this case,

A = "the screen came from Philips"

B = "the screen is unsatisfactory"

So:

P(Philips | Unsatisfactory) = P(Unsatisfactory | Philips) * P(Philips) / P(Unsatisfactory)

We are given:

P(Unsatisfactory | Philips) = 4% = 0.04

P(Philips) = 45% = 0.45 (since 55% came from Corning Inc.)

P(Unsatisfactory) = P(Unsatisfactory | Corning Inc.) * P(Corning Inc.) + P(Unsatisfactory | Philips) * P(Philips)

= 1% * 55% + 4% * 45% = 0.55% + 1.8% = 2.35%

So:

P(Philips | Unsatisfactory) = 0.04 * 0.45 / 0.0235 = 46.48%

So the probability that a randomly chosen unsatisfactory screen came from Philips is 46.48%.

The 4 properties of multiplication are Associative Property, Commutative Property, Distributive Property, and Identity Property.

The properties of multiplication are particular rules that are used while multiplying numbers. These properties help simplify expressions easily and, hence, have a significant role in solving all kinds of mathematical expressions, whether algebraic expressions, fractions, or integers.

Associative Property: (P × Q) × R = P × (Q × R)

For example, (4 × 5) × 3 = 4 × (5 × 3) = 60.

Commutative Property: P × Q = Q × P

For example, 3 × 4 × 2 = 2 × 3 × 4 = 24.

Distributive Property: P(Q + R) = PQ + PR; P(Q - R) = PQ - PR

For example, 3(2 + 4) = (3 × 2) + (3 × 4) = 6 + 12 = 18.
