A string of length 160cm is cut into 2 pieces, in the ratio 3:5. Find the length of each piece

r-ruslan [8.4K]

Answer: One piece is 60 cm and the other is 100cm

Lets think, "x" as the length of each piece.

3 + 5 is 8. So,

x/160 = 3/8

x= 3/8*160

x= 60

--------------------------------------------------------------------------------------------------------------

x/160 = 5/8

x= 5/8 * 160

x= 100

Brainliest pls if it was correct!

Find the slope of the line. Write your answers in simplest form

dmitriy555 [2]

Answer:

-3/5

Step-by-step explanation:

using the picture and the rise over run method, you can see that from the coordinate farthest to the right, you move 3 spaces up (positive), and 5 spaces to the left (negative), which gives you your answer of -3/5.

You can also use the formula to find the slope:

1) y₂-y₁/x₂-x₁

2) -2-1/1-(-4)

3) -3/5

Assume a significance level of alpha = 0.05 and use the given information to complete parts (a) and (b) below. Original claim

laiz [17]

Answer:

The correct option is B

The correct option is D

Step-by-step explanation:

From the question we are told that

The level of significance is $\alpha = 0.05$

The p-value is $p = 0.2761$

Considering question b

Given that the $p< \alpha$ then the null hypothesis is rejected

Considering question b

Given that the original claim is The standard deviation of pulse rates of a certain group of adult males is more than 11 bpm

Then the null hypothesis is $H_o : \sigma = 11$

The reason why the null hypothesis is write like this above is because a null hypothesis expression can not contain only a > or a < but only allows = $\le , \ and \ \ge$

and the alternative hypothesis is $H_a : \sigma > 11$

Now given that the null hypothesis is rejected, it mean that there is sufficient evidence to support original claim

olya-2409 [2.1K]

Answer:

1.5 or 3/2

Step-by-step explanation:

V = l x w x h

4 1/3 = 3/4 x 4 x L

3/4x4 = 3

3L = 4 1/2

Divide by 3

Length = 1.5 or 3/2
