Complete question :

A college football coach wants to know if the is a correlation between his players' leg strength and the time it takes for them to sprint 40 yards. he sets up the following test and records the data:

Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The tables shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for seven randomly selected players. What is the equation of the line of best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions?

Using a regression calculator :

The equation of line of best fit is :

ŷ = 0.1073X + 4.5365

Slope or gradient = 0.1073

Intercept = 4.5365

X = independent or predictor variable (leg press)

Y = predicted variable (40 yard dash)

B)

X = 22

Y = 0.1073(22) + 4.5365

Y = 6.8971

Y = 6.9

Answer:

a = -2

Step-by-step explanation:

The graphs of the lines would have to be parallel.  So they must have the same slope.   2x + y = -1 changed to slope-intercept form is y = -2x - 1.  Therefore, the slope of that line is -2.   y = ax is in slope-intercept form where the slope is a.  So, a must equal -2.

Answer:

2 fractions are equal

Step-by-step explanation:

We say that two quantities are proportional if one is always the same multiple of the other.

Say a recipe calls for 2 cups of flour to 3 eggs. That proportion, 2 cups flour : 3 eggs, will always stay the same, no matter how many serving we make. If we make 2 servings, we'd double to 4 cups and 6 eggs, but that wouldn't change the proportion. After all,

[tex]\frac{2}{3}=\frac{4}{6}[/tex]

Answer:

31: |8| +|18|=|26|

33: |2| +|9|=|11|

since these numbers are already positive, the numbers will stay the same just add the bars in front and after it.

Answer:

x = -3  and x = - 3/4

Step-by-step explanation:

We can use the quadratic formula to solve for x, considering a = 4 , b = 15, and c = 9:

[tex]x=\frac{-b+/- \sqrt{b^2-4a*c} }{2*a} \\x=\frac{-15+/- \sqrt{(-15)^2-4*4*9} }{2*4}\\x=\frac{-15+/- \sqrt{81} }{8}\\x=\frac{-15+/- 9 }{8}=-\frac{6}{8} \,\,or\,\,-\frac{24}{8} \\x=-\frac{3}{4}\,\,or\,\,x=-3[/tex]

[tex]7 \frac{1}{2} [/tex]

First, convert any mixed numbers to fractions. An easy way to convert:

[tex]4 \frac{1}{2} = 4 \times 2 + 1[/tex]

[tex] \frac{9}{2} \div \frac{3}{5} [/tex]

Then, apply the fractions formula for division.

[tex] \frac{9 \times5 }{2 \times 3} = \frac{45}{6} [/tex]

Then, simplify.

[tex] \frac{45}{6} = 7 \frac{1}{2} [/tex]

Answer:

We conclude that:

csc (U) = 26 / 24        

Step-by-step explanation:

Given

To determine

csc (U) = ?

Using the trigonometric ration

sin Ф = opposite / hypotenuse

substituting Ф = U, opposite = 24, hypotenuse = 26

sin (U) = 24/26

We know that: csc (U) = [1 ] / [sin(U)]

Therefore,

csc (U) = [1 ] / [sin(U)]

            = 26 / 24

Therefore, we conclude that:

csc (U) = 26 / 24

Answer:

$549

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 3050 × 0.06 × 3 = 549

I = $ 549.00

The simple interest accumulated

on a principal of $ 3,050.00

at a rate of 6% per year

for 3 years is $ 549.00.

Answer:

0.328 [tex]m^{2}[/tex]

Step-by-step explanation:

820mm = 82cm = 0.82m

400mm = 40cm = 0.40m

0.82 x 0.40 = 0.328

If a rectangular tray is 820mm long and 400mm wide. Its area in m²​ will be: 0.328m²

Using this formula

Area=Length × Width

First step is to covert from millimeter to meter

1 millimeter=0.1 centimeter

Hence:

Length=820mm×0.1÷100

Length=0.82m

Width=400mm×0.1÷100

Width= 0.40m

Let plug in the formula

Area=0.82m x 0.40m

Area= 0.328m²​

Inconclusion If a rectangular tray is 820mm long and 400mm wide. Its area in m²​ will be: 0.328m².

The Given integral is :

∫x²√x³ + 37 dx ; u = x³ + 37

Answer:

2/9(x³ + 37)^3/2 + C

Step-by-step explanation:

∫x²√x³ + 37 dx ; u = x³ + 37

∫x²√u dx

Since u = x³ + 37

Differentiate u with respect to x

du/dx = 3x²

du = 3x²dx

dx = du / 3x²

∫x²√u dx = ∫x²√u du/3x²

1/3x²∫x²√u du

1/3 ∫ √u du

Integrating √u with respect to u

1/3 ∫ u^1/2 du

1/3 [u^(1/2+1) / 1/2 + 1] + C

1/3 [u^3/2 / 3/2] + C

1/3 u^3/2 * 2/3 + C

1/3*2/3 u^3/2 + C

2/9 u^3/2

u = x³ + 37

2/9(x³ + 37)^3/2 + C

Answer:

One-sixth or 1/6

Step-by-step explanation:

A probability density curve satisfies several rules: It never goes below the horizontal axis, i.e. it's never negative. ... The chance of the quantity falling between a and b is the area under the curve between the point a and b.

The height of density curve is 1/6. Therefore, option B is the correct answer.

In probability theory, a probability density function, or density of a continuous random variable, is a function whose value at any given sample in the sample space can be interpreted as providing a relative likelihood that the value of the random variable would be close to that sample.

A density curve is always on or above the horizontal axis. The area underneath a density curve is exactly 1. The area under a density curve and above any range of values is the relative frequency of all observations that fall in that range.

The curve will never dip below the x ≥ Height>0

Area under the curve=Area of a rectangle with length=height of curve width=6

=Height of curve × 6

Area under the curve = 1

⇒ Height of curve × 6=1

=1/6

The height of density curve is 1/6. Therefore, option B is the correct answer.
