The point slope form of a line that has a slope of -2 and passes through point (5,-2) is shown below.

1 answer:

4 0

Insert the point, (5,-2) with the slope of the line to figure out the equation. You can either use point-slope form, or plug it for for slope-intercept form.

Slope-intercept form:
-2 = -2(5) + b
-2 = -10 + b
Add 10 on both sides
8 = b

Thus,

y = -2x + 8

Answer is B

(-2,8) (1,2)
m=2-8/1-(-2)
m=-6/3
m= -2
y=-2x+b
(-2,8)
8=-2(-2)+b
8=-4+b
12=b
b=12
y=-2x+12
Hope this helps!

Emily is making bows using ribbon. She has two pieces of ribbon to use. One is 23 yards long. The other is 4 1/4 yards long. She

Sliva [168]

Answer:

Step-by-step explanation:

In total, Emily has $23+4\frac{1}{4}=27\frac{1}{4}=\frac{109}{4}$ yards of ribbon.

Each bow requires $1\frac{5}{6}=\frac{11}{6}$ yards of ribbon

To figure out, we divide total amount of ribbon by amount each bow needs:

Number of bows = $\frac{\frac{109}{4}}{\frac{11}{6}}=14.86$

So the maximum number of "complete" bows Emily can make is 14

Answer:

The $96^{th}$ percentile is 1.751

Step-by-step explanation:

The following information is missing in the question:

Mean,

$\mu = 0^\circ C$

Standard Deviation,

$\sigma = 1^\circ C$

We are given that the distribution of distribution of errors is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.96

$P( X < x) = P( z < \displaystyle\frac{x - 0}{1})=0.96$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x}{1} = 1.751\\\\x = 1.751$

$P_{96} = 1.751$

1.751 degree Celsius is the thermometer reading corresponding to $96^{th}$ percentile.
