1+(11-7x)^1/4=4
(11-7x)^1/4=4-1
(11-7x)^1/4=3
11-7x=3(4)
-7x=12-11
-7x=1
x=-1/7

Think about tossing two coins.

ankoles [38]

Given:

Two coins are tossed.

To find:

1. P(H on first coin)?

2. P(H on second coin)?

3. List the paired outcomes for tossing two coins.

4. How many ways are there for two coins to land?

5. What is P(HH)?

Solution:

If a a coin is tossed, then we have to possible outcomes, i.e., heads (H) and tails (T).

It is given that two coins are tossed.

1. The probability of getting a heads on first coin is:

$P(H \text{ on first coin})=\dfrac{1}{2}$

2. The probability of getting a heads on second coin is:

$P(H \text{ on second coin})=\dfrac{1}{2}$

3. If two coins are tossed, then the total possible outcomes are:

$\{HH,HT,TH,TT\}$

4. The number of ways for two coins to land is 4.

5. The probability of the heads on both tosses is:

$P(HH)=\dfrac{1}{4}$

Therefore, the required solution are:

1. $P(H \text{ on first coin})=\dfrac{1}{2}$

2. $P(H \text{ on second coin})=\dfrac{1}{2}$

3. List of possible outcomes is $\{HH,HT,TH,TT\}$ .

4. Number of possible outcomes is 4.

5. $P(HH)=\dfrac{1}{4}$

Someone plz. help me with 7 and 8

7.) the equation of the circle is
(x - 3)^2 + (y - 4)^2 = 25

If you substitute the point in you get
(6-3)^2 + (8-4)^2 = 25
3^2 + 4^2 = 25
9 + 16 = 25
25 = 25

Both sides of the equation are the same so it proves it lies on the circle

8.) you add the x coordinates together and divide by 2
7 + 4 = 11
11/2 = 5.5
You use +7 because you need to find the midpoint.
You then add 5.5 to - 7 or - 5.5 from 4
-7 + 5.5 = - 1.5

You do the same for y coordinates
6+5 = 11
11/2 = 5.5
6-5.5 = 0.5

So the coordinates of Rachel's house are
(-1.5, 0.5)

This figure represents a small weight that is to be covered on all sides with a floral fabric. How much fabric is needed to cove

Anon25 [30]

Answer:

77.5 cm²

Step-by-step explanation:

We need to find the surface area of the rectangular prism.

Total surface area = 2(lw + wh + lh)

where:

l = length of base
w = width of base
h = height of prism

Given dimensions:

$\textsf{length}=\sf 6\dfrac12\:cm=6.5\:cm$

$\textsf{width}=\sf 2\dfrac12\:cm=2.5\:cm$

$\textsf{height}=\sf 2\dfrac12\:cm=2.5\:cm$

Substituting these value into the formula:

$\begin{aligned}\textsf{Surface area} & =\sf 2(6.5 \cdot 2.5+2.5 \cdot 2.5+6.5 \cdot 2.5)\\ & = \sf2(16.25+6.25+16.25)\\ & = \sf 2(38.75)\\ & =\sf77.5\:cm^2 \end{aligned}$

Therefore, 77.5 cm² of fabric is needed to cover the weight.
