Answer:

$d=5$

Step-by-step explanation:

you have to use the distance formula, making the origin (0,0) the 1st point and (4,0) the second point.

$d=\sqrt{(x_{2} -x_{1})^{2} + (y_{2} -y_{1})^{2} }$

$d=\sqrt{(4-0)^{2}+(3-0)^2 }$

$d=\sqrt{(4)^2+(3)^2}$

$d=\sqrt{16+9}$

$d=\sqrt{25}$

$d=5$

Which expression is equivalent to 1/8x- 1/2?

pychu [463]

This is done by factoring. 1/8 is smaller than 1/2, so we can factor a 1/8 out of 1/2. This is what that looks like: $\frac{ \frac{1}{2} }{ \frac{1}{8} }$ , because factoring after all is a form of division. When we divide a fraction by a fraction, we bring the lower fraction up and flip it to multiply, giving us this: $\frac{1}{2} * \frac{8}{1}$ . This of course reduces to 4. So when we factor out 1/8, what we will have then is $\frac{1}{8} (x-4)$ , choice D from above.

A manufacturing process produces bags of cookies. The distribution of content weights of these bags is Normal with mean 15.0 oz

NeTakaya

Answer:

100 bags

Step-by-step explanation:

S.E = σ/ √n

0.1 = 1 / √n

Square both sides

0.1² = 1² / n

0.01 = 1 / n

0.01n = 1

n = 1 / 0.01

n = 100

What is an equation of a line in point slope form that passes through the points (7,-8) and (-4,6)?

maw [93]

y=kx+b

for (7,-8): -8=7k+b. (function 1)

for (-4,6): 6=-4k+b (function 2)

Use function 2 - function 1

we get: 14=-11k

k=-14/11------>slope is -14/11

Now we know that first two options are wrong since they have the wrong slope for the function.

Plus -14/11 back to function 1/ or 2. Both are correct and can give you the answer. In this case I would plug it back to function 2.

6=14*4/11+b

b=66/11-56/11

b=10/11

We get y=-14/11x+10/11

subtract both side by 6.

y-6=-14/11x+10/11-66/11

y-6=-14/11x-56/11

y-6=-14/11(x+4)

So C is correct

Mandy shaded the fraction strip below to represent a fraction Shade the fraction strip below so that it represents a fraction th

Aleksandr-060686 [28]

Your question is missing the figure, so the figure for your question is attached below:

Answer:

shade 2 strips out of 4 to get fraction strip equivalent to Mandy's fraction strip

Step-by-step explanation:

As Mandy shaded the 3 trips out of the total six strips. It shows the fraction of $\frac{3}{6}$

and $\frac{3}{6}=\frac{1}{2}$

To shade the given fraction strip so that it represents a fraction that is equivalent to Mandy's fraction strip, we should shade 2 stripes out of 4 that is equivalent to $\frac{1}{2}$

i.e. $\frac{2}{4}=\frac{1}{2}$

My Fraction Strip is equivalent to Mandy's Fraction Strip because both are equal to $\frac{1}{2}$
