Find the length of the line segment whose endpoints are (-5,6) and (6,6)

umka21 [38]

Answer: 11 units

Step-by-step explanation:

Use the distance formula: $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }$

$(x_{1}, y_{1})=(-5, 6)\\(x_{2}, y_{2})=(6, 6)\\\\\sqrt{(6-(-5)^{2}+(6-6)^{2}} =\sqrt{(11)^{2}+(0)^{2}} =\sqrt{121+0}=\sqrt{121}=11$

The grams of sugar per serving for three brands of cereal are 4 g, 10 g, and 14 g. The probability of choosing a cereal with 4 g

Sergio039 [100]

Answer:

$Expected\ Value = 9$

Step-by-step explanation:

Given

Cereal A

$Probability = \frac{1}{4}$

$Grams = 4$

Cereal B

$Probability = \frac{5}{8}$

$Grams = 10$

Cereal C

$Probability = \frac{1}{8}$

$Grams = 14$

Required

Determine the expected value of grams of sugar

This is calculated by multiplying the probability and grams of sugar in each cereal.

The results of the products are then added together

i.e.

$Expected\ Value = \frac{1}{4} * 4 + \frac{5}{8} * 10 + \frac{1}{8} * 14$

$Expected\ Value = 1 + \frac{50}{8}+ \frac{14}{8}$

$Expected\ Value = 1 + 6.25 + 1.75$

$Expected\ Value = 9$

Hence;

The expected value of grams of sugar is 9 grams

Which best describes the relationship between the line that passes through the points (9, -1) and (11,3) and the line that passe

noname [10]

Answer:

Option B, parallel

Step-by-step explanation:

for the first line,

[3-(-1)]/[11-9]

= 4/2 = 2

for the second line,

(0-(-4))/(-4-(-6))

= 4/2 = 2

Both has same slope so they're parallel but it doesn't seem like they are the same line
