AB=10, AD=24. What is the value of AC+AD?<br><br>​
Rainbow [258]

Answer:

52

Step-by-step explanation:

Given:

AB = 10, AD =24

Required:

Value of AC + BD

SOLUTION:

AC = BD (both are diagonals of the rectangle)

Use pythagorean theorem to find AC.

Thus:

AB² + AD² = BD²

Plug in the values

10² + 24² = BD²

676 = BD²

√676 = BD

26 = BD

BD = AC = 26

Therefore,

AC + BD = 26 + 26 = 52

The scatter plot shows the number of minutes people had to wait for service at a restaurant and the number of staff available at
tekilochka [14]

The slope of a linear regression is the rate of change of the line of the best fit

  • The interpretation of the slope is that the wait time per staff is 1.62 minutes
  • The slope value is realistic

The linear regression is given as:

y = -1.62x + 18

Where

  • y represents the wait time
  • x represents the number of staff

Using the above representations, the slope means that the wait time per staff is 1.62 minutes

Also, the slope value is realistic because time can be measured in decimals

People with restless leg syndrome have a strong urge to move their legs to stop uncomfortable sensations. People with fibromyalg
USPshnik [31]

Answer:

0.1833

Step-by-step explanation:

Given:

% of people with fibromyalgia = 2%

Probability of having a restless leg syndrome for people with fibromyalgia = 0.33

Probability of having a restless leg syndrome for people without fibromyalgia = 0.03

Take F as event of having fibromyalgia

Take R as event of having restless leg

Required:

Find the probability that a person with restless leg syndrome has fibromyalgia.

To find the probability that a person with restless leg syndrome has fibromyalgia, we have: P(F/R)

P(F/R) = \frac{P(F n R)}{P(R)}

P(F/R) =\frac{P(R/F) * P(F)}{P(R/F) * P(F) + P(R/F^c) * P(F^c)}

Where,

P(R/F) = 0.33

P(F) = 2% = 0.02

P(R/F') = 0.03

P(F') = 1 - 0.02 = 0.98

Therefore,

P(F/R) = \frac{0.33 * 0.02}{0.33*0.02 + 0.03*0.98}

= 0.1833

Probability a person with restless leg syndrome has fibromyalgia = 0.1833

Need help please!! I’m confused
trapecia [35]

Answer:

y = -0.2x + 3.8

Step-by-step explanation:

it states it has been 7 weeks. 0.2 x 7 is 1.4. That means they started with 2.4 + 1.4 meters thick of ice sheet, which is 3.8, which is the number they started with. So, b = 3.8 and it says it melts 0.2 so it's a negative, which is -0.2 as slope. So, y = -0.2x + 3.8
