I need to know how to find x

Mathematics
1 answer:
enyata [817]3 years ago
5 0

Answer:

x = \frac{20}{3}

Step-by-step explanation:

ΔABC and ΔEDC are similar triangles ( AA ), hence the ratios of corresponding sides are equal, that is

\frac{AB}{ED} = \frac{BC}{DC}, substitute values

\frac{x}{4} = \frac{5}{3} ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = \frac{20}{3}

The temperature is 78 °F at 2:00 in the afternoon. If the temperature drops 4 °F every hour after that, what is the temperature
Galina-37 [17]

Answer:

The answer to your question is: 54°F

Step-by-step explanation:

Data

Ti = 78°F

Initial hour = 2:00

Temperature drops 4°F every hour

Temperature at 8:00 = ?

Process

                      2:00                  

                       3:00             78-4 =     74°F

                      4:00              74-4 =      70°F

                      5:00              70-4 =      66°F

                      6:00              66-4 =      62°F

                       7:00             62-4 =     58°F

                      8:00              58-4 =      54°F

7. Suppose we are interested in comparing the average years of service accountants have between males and females to see if ther
Scorpion4ik [409]

The 99% confidence interval for the difference between the average years of service between men and women would be = 3.43.

<h3>What is confidence intervals?</h3>

Confidence interval is defined as the statistical parameter that is used to know if a set of values would fall within a certain range of population or not.

Using the statistical table, the value of 99% or 0.99 confidence interval has a z-score = 2.576

The standard error that exists between the bothe value = SD/Ö

Where SD = difference between the standard deviations = 8.39 - 4.39 = 4

Where ñ = different between the average years of service = 9.62

Standard error= 4/√9.62 = 4/3.01 = 1.33

The confidence interval = 2.576 × 1.33 = 3.43.
