Eric's tackle box has 4 sections for fishing lures. Eric has 28 lures.
He wants to put the same number of lures in each section.
How many lures should he put in each section?

Answer: 72.78% of the drivers are traveling between 70 and 80 miles per hour based on this distribution.

Step-by-step explanation:

Let X be a random variable that represents the speed of the drivers.

Given: population mean : M = 72 miles ,

Standard deviation: s= 3.2 miles

The probability that the drivers are traveling between 70 and 80 miles per hour based on this distribution:

[tex]P(70\leq X\leq 80)=P(\frac{70-72}{3.2}\leq \frac{X-M}{s}\leq\frac{80-72}{3.2})\\\\= P(-0.625\leq Z\leq 2.5)\ \ \ \ \ [Z=\frac{X-M}{s}]\\\\=P(Z\leq2.5)-P(Z\leq -0.625)\\\\\\ =0.9938-0.2660\ \ \ [\text{Using p-value calculator}]\\\\=0.7278[/tex]

Hence, 72.78% of the drivers are traveling between 70 and 80 miles per hour based on this distribution.

Step-by-step explanation:

The mean is the average so add up all values of the data points and divide by the amount of data points.

Answer:

11

Step-by-step explanation:

add all the x's to get the total

Answer:

The new center is the point (-x, y)

Step-by-step explanation:

When you reflect a point across the y-axis, the x-coordinate changes to its opposite (additive inverse).

See the attached image for an example.

The circle on the right has center (3, 1).  When reflected across the y-axis, the reflected center is (-3, 1).

Answer:

x = -8, y = 4

Step-by-step explanation:

3x + 3y = -12 (1)

x + 6y = 16 (2)

Multiply (2) by 3

3x + 18y = 48 (3)

3x + 3y = -12 (1)

Subtract (1) from (3) to eliminate x

18y - 3y = 48 - (-12)

15y = 48 + 12

15y = 60

y = 60/15

y = 4

Substitute y = 4 into (1)

3x + 3y = -12 (1)

3x + 3(4) = -12

3x + 12 = -12

3x = -12 - 12

3x = -24

x = -24/3

x = -8

x = -8, y = 4

and the question is? I'm confused

I think its 10 pls dont get mad at me if its wrong.

Step-by-step explanation:

if you see x and then 10 you can see they line up

Answer:

{x | x < 2 and  x < -4 }

Step-by-step explanation:

Given the inequality 5(x - 2)(x + 4) > 0?

This also means x - 2 < 0 and x + 4<0

For x - 2 < 0

Add 2 to both sides

x - 2 + 2 < 0 + 2

x < 2

Similarlry for x + 4 <0

Subtract 4 from both sides

x+4-4 < 0 -4

x < 0 -4

x < -4

x < 2 and  x < -4

Hence the required solution is {x | x < 2 and  x < -4 }

Answer:

The answer is 19.

Step-by-step explanation:

This is because the sequence adds up by 7 each time. Have a nice day!

Answer:

19

Step-by-step explanation:

The sequences are adding 7, so 12 + 7= 19

Answer:

[tex]MN = \sqrt{14[/tex]

Step-by-step explanation:

Given

[tex]NO = 12[/tex]

[tex]OP = 2.5[/tex]

[tex]OQ = 4.5[/tex]

Required

Find MN

First, we calculate QP using Pythagoras theorem

[tex]OQ^2 = OP^2 + QP^2[/tex]

[tex]4.5^2 = 2.5^2 + QP^2[/tex]

[tex]20.25 = 6.25 + QP^2[/tex]

Collect like terms

[tex]QP^2 = 20.25 - 6.25[/tex]

[tex]QP^2 = 14[/tex]

Take square roots

[tex]QP = \sqrt{14[/tex]

To solve MN, we have:

[tex]MN = OP[/tex]

So:

[tex]MN = \sqrt{14[/tex]

Answer:

The one on the right. y< -x/2 - 1

Answer:

You could use 3.14 or 22/7

Step-by-step explanation:

It should be what you're asking, if not, tell me and I'll give you another answer.

:)

Answer:

use 22/7 or 355/133, but 355/133 is not very commonly used and is unwieldy.

Answer:

Decimal:

h = 4.2 ft

Fraction:

[tex]h=4\frac{1}{5}[/tex] ft

Step-by-step explanation:

[tex]\frac{9}{15} :\frac{h}{7}[/tex]

Cross multiply.

h · 15 = 9 · 7

Simplify.

15h = 63

Divide each side by 15.

15h ÷ 15 = 63 ÷ 15

Simplify.

h = 4.2

Answer:

x = 9

(5x9) - 1° = 45 - 1 or 44°

Step-by-step explanation:

the little square indicates the angle is a right angle, measuring 90°

therefore, you can solve for 'x' by creating this equation:

46 + 5x-1 = 90

45 + 5x = 90

5x = 45

x = 9

Answer:

36

Step-by-step explanation:

12 x 3 = 36

Answer:

Step-by-step explanation:

21 is the side opposite the angle you want.

67 is the hypotenuse. Those two sides define the Sin

Sin(theta) = opposite / hypotenuse

Sin(theta) = 21 / 67

Sin(theta) = .313432

theta or x = sin-1(0.313432)

x = 18.27

Answer:

Step-by-step explanation:

The k is indicative of movement either up or down, while h is indicative of movement that is either right or left. The blue graph moves both to the right and down to get to the position of the red graph. On the blue graph, locate the point (0, 1). That point moves from a y-location of 1 to a y-location of -2, meaning that it moves down 3 units; therefore, the value of k is -3.
