1 answer:
zhenek [66]3 years ago
7 0

Answer:

y = 1/2x + 1.

Step-by-step explanation:

Use the point-slope form of a straight line:

y - y1 = m(x - x1)     (where m=slope and(x1,y1) is a point on line).

y - 3 = 1/2(x - 4)

y = 1/2x - 2 + 3

y = 1/2x + 1.

Proving that EFGH is a square: points E,F,G,H
separate the sides of the square ABCD into two lines. if AE=BF=CG=DH then
AH=DG=EB=FC and it shows that if we connect the points E,F,G,H to each other with line we will have a square

(141 + 162 + S) / 3 = 160

(303 + S) / 3 = 160

101 + S/3 = 160
-101 -101
S/3 = 59
*3 *3

S= 177

Jacques needs at least a 177 to get a 160 average

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5
Doss [256]

Answer:

Using the Empirical Rule, we find that .997 (99.7%) of students have grade point averages that are between 1.23 and 3.81.

Step-by-step explanation:

Calculate the z-scores corresponding to a GPA of 1.23 and 3.81.

  • \displaystyle z=\frac{1.23-2.52}{.43} = \frac{-1.29}{.43}= -3
  • \displaystyle z=\frac{3.81-2.52}{.43}= \frac{1.29}{.43}  =3

We want to find the area between the z-scores of -3 and 3.

The <u>Empirical Rule</u> tells us that 99.7% of the data lies <em>within three standard deviations</em> under the normal curve.

Therefore, the <u>area</u> between <em>-3 < z < 3</em> is about <u>.997</u>, or around <u>99.7%</u>.

K = 4a + 9ab solve for a
marysya [2.9K]

Answer:

a=\frac{K}{4+9b}

Step-by-step explanation:

K=4a+9ab

Switch sides:

4a+9ab=K

Factor out a:

a\left(4+9b\right)=K

Divide both sides by: (4+9b)

\frac{a\left(4+9b\right)}{4+9b}=\frac{K}{4+9b}

a=\frac{K}{4+9b}
