**Answer:**

**Step-by-step explanation:**

**Given :** You planned to work on a project for about 4 and a 1/2 hours today.

**To Find :**If you have been working on it for 1 and 3/4 hours, how much more time will it take?

**Solution:**

Total time to be spent on project today =

You have been working on it for hours =

Remaining time =

=

=

**Hence it will take hours more .**

Blood potassium level, continued. Judy’s measured potassium level varies according to the Normal distribution with with μ=3.8 and σ=0.2mmol/l. Let’s consider what could happen if we took 4 separate measurements from Judy. What is the blood potassium level L such that the probability is only 0.05 that the average of 4 measurements is less than L?

**Answer:**

The number of ways is 13860 ways

**Step-by-step explanation:**

**Given**

Senior Members = 10

Junior Members = 12

**Required**

Number of ways of selecting 6 students students

The question lay emphasis on the keyword **selection; **this implies combination

**From the question, we understand that**

*4 students are to be selected from senior members while 2 from junior members;*

**The number of ways is calculated as thus;**

**Ways = Ways of Selecting Senior Members * Ways of Selecting Junior Members**

*Hence, the number of ways is 13860 ways*

**Step-by-step explanation:**

**Answer:**

The answer is 5.8 times a second

**Step-by-step explanation:**

Divide 1044 by 180 (The number of seconds in 3 minutes)

To calculate the rate in** revolutions per second**, we first convert the 3 minutes into seconds, which is 180 seconds. We then divide the total number of revolutions, 1044, by 180. This gives us a rate of 5.8 revolutions per second.

To solve this problem, we need to **convert minutes **into seconds because the rate is asked in revolutions per second.

Let's start by figuring out how many seconds are in those 3 minutes. We know that in 1 minute, there are 60 seconds. So, 3 minutes would be 3 times 60, which is 180 seconds.

Next, we will calculate the rate by dividing the total number of revolutions, which is **1044**, by the total number of seconds, which is **180**. So, 1044 ÷ 180 = 5.8.

This means that the propeller spins at a rate of 5.8 revolutions per second.

56 mph + 89 = idont know any thing

The electric generator has an efficiency of approximately 66.67%, which means that 66.67% of the input energy is converted into usable electrical power.

The question wants to know about the **efficiency** of an **electric generator**. The efficiency of any engine or generator is defined as the ratio of useful energy output to the energy input. In this case, the energy input to the generator is 120 hp (horsepower) and the useful energy output (i.e electrical power) is 80 hp.

The formula used to calculate the efficiency is: Efficiency = (**useful energy output** / **energy input**) * 100% , Using this formula, the efficiency of the generator would be (80 / 120) * 100% = 66.67 % .

This means that 66.67% of the energy supplied to the generator is successfully converted into electrical power, while the rest is likely lost as heat or other forms of non-usable energy.
