Answer:

**Answer:**

4.8

**Step-by-step explanation:**

When you multiply two negative number you get a positive number.

Find the square root of 6.4 upto two decimal place

Suppose that a random sample of size 36 is to be selected from a population with mean 50 and standard deviation 7. What is the approximate probability that will be within 0.5 of the population mean?

What is 78 radishes planted in a 13-foot long row written as a unit rate per inch

B(n)=2^n A binary code word of length n is a string of 0's and 1's with n digits. For example, 1001 is a binary code word of length 4. The number of binary code words, B(n), of length n, is shown above. If the length is increased from n to n+1, how many more binary code words will there be? The answer is 2^n, but I don't get how they got that answer. I would think 2^n+1 minus 2^n would be 2. Please help me! Thank you!

I thought of a number. This number double is 7 less than 29. What is my number? hurry please

**Answer:**

The length of the wire is 76.19 m.

**Step-by-step explanation:**

It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.

It means base of the right angled triangle is 40 m.

The wire makes an angle of 58deg 20min with the ground.

1 degree = 60 min

Using this conversion convert the given angle in degree.

In a right angled triangle

**Therefore the length of the wire is 76.19 m.**

**Answer:**

y = 3x + 7

(Not sure what the question was so, I just put it in slope intercept form)

**Step-by-step explanation:**

Let x be Steve's age.

Steve = x

Steve's Mom = y

Now let's create an equation:

y - 7 = 3x

y = 3x + 7

(Not sure what the question was so, I just put it in slope intercept form)

Please let me know if I misunderstood the question that way I can help you! <3

**Answer:**

Steve's mom is 65.

**Step-by-step explanation:**

Let s = Steve's age.

s + (3s - 7) = 65

4s - 7 = 65

4s = 72

s = 18

Check:

Steve is 18

His mom is (3 * 18) - 7 = 54 - 7 = 47

14 + 47 = 65

Yep.

18 + 47 = 65

**Answer:**

y<13/2

**Step-by-step explanation:**

5y + 4 < 3y + 17

5y-3y<-4+17

2y<13

y<13/2

**Answer:**

y<6.5

**Step-by-step explanation:**

5y+4<3y+17

Subtract 3 from both sides

2y+4<17

Subtractc4 from both sides

2y<13

Divide both sides by 2

y<6.5
