Hi there!

For this problem, pretty much add all of them and then subtract with 22 to find how much Jen ran on Friday.

Monday+Tuesday+Wednesday+Thursday:

Simplify all terms and find all common denominators:

Common denominator: 8

4 \frac{3}{4} = 4 \frac{6}{8}

5 \frac{1}{8} = 5 \frac{1}{8}

6 \frac{1}{4} = 6 \frac{2}{8}

Combine all terms:

4 \frac{6}{8} + 5 \frac{1}{8} + 6 \frac{2}{8} = 15 \frac{9}{8}

Simplify 15 9/8 or else can’t subtract with 22.

9/8 = 1 \frac{1}{8}

15 + 1 \frac{1}{8} = 16 \frac{1}{8}

Turn 22 into 21 8/8...

Subtract: 21 8/8 with 16 1/8

21 \frac{1}{8} - 16 \frac{1}{8} = 5 \frac{7}{8}

This means that 5 7/8 is how much mile Jen must run on Friday to reach her goal.

Answer:

Option B: 0.4

Step-by-step explanation:

We have 20 dots.

Such that each column represents the repetitions for each proportion.

So:

0.1 -> 3 times

0.2 -> 1 time

0.3 -> 4 times

0.4 -> 6 times

0.5 -> 3 times

0.6 -> 3 times

Now we can compute the mean of these values, and that will be the best estimation we can make with the given data.

Remember that for a set of N values:

{x₁, x₂, ..., xₙ}

The mean is:

M = \frac{x_1 + x_2 + ... + x_n}{N}

In this case we have the set of 20 points described above, then the mean is:

M = \frac{3*0.1 + 1*0.2 + 4*0.3 + 6*0.4 + 3*0.5 + 3*0.6}{20} = 0.37

Rounding to the first place after the decimal point, we get:

M = 0.4

Then the correct option is option B.

Plz I need help with this I am struggling failing math
Goryan [66]

Answer:

CB = 5, m\angle{BDA} = 23^\circ

Step-by-step explanation:

Assuming that the marks next to angle D mean that \angle{BDA} \cong \angle{BDC}, then there is enough information to conclude that the two right triangles are congruent (HA theorem--hypotenuse/angle).

Then all the corresponding parts of the two triangles are congruent, including segments BA and BC, making them the same length.

4x + 1 = 9x - 4

Solving for x,

1 = 5x - 4

5 = 5x

1 = x

Pluggint x = 1 into the two expressions reveals that the length of segment CB is 5.

The two small angles at D are congruent, so m\angle{BDA}=23^\circ.

Y= 3x + 1
Sonbull [250]

Answer: The correct option is option 6, (-4,-11).

Step-by-step explanation: You subsitute 2x-3 for y.

2x-3=3x+1

-x=4

x=-4

Plug in -4 for x in an equation.

y = -8 - 3

y = -11

(-4,-11)
