A piece of wood is 4 feet long. Are 4 pieces of wood longer than 4 yards?

Zanzabum

1wd = 4ft
3 ft = 1 yd
1yd x 4=4 yd
4 yd = 12ft
4 wd x 4 = 16ft
Yes, 4 pieces of wood are longer than 4 yards by 4 ft or 1 1/3yd

What is the different possible results from a probability model

Wewaii [24]

“Equally likely outcomes in probability.
In some sample spaces, it is reasonable to estimate or assume that all outcomes in the space are equally likely (that they occur with equal probability). For example, when tossing an ordinary coin, one typically assumes that the outcomes "head" and "tail" are equally likely to occur.”

What is the y=Mx+b of this equation

Monica [59]

Answer:

$y = - 6x - 8$

Step-by-step explanation:

The y-intercept is where the line itersects the y-axis, which is the dark vertical line. This is -8 represented as the constant in the equation.

To find the slope, find the rise over run. Every time the line goes over 1 it goes down 6, so the slope would be -6.

The volume V of a right‑circular cylinder is computed using the values d = 3.1 m for the diameter and h = 6.6 m for the height.

pantera1 [17]

Answer:

6%

Step-by-step explanation:

A function f(x) can by approximated at and around a point, say x = a by,

f(x) = f(a) + f'(a)(x-a)

where, $f'(x)=\frac{df}{dx}$

Here, volume V is a function of radius r and height h. In the 2 dimensional case, we have to take the partial derivatives.

Given,

$V=\pi r^2h$

or, $dV=\frac{\partial V }{\partial r}dr+ \frac{\partial V }{\partial h}dh$

at r = 1.55 m and h = 6.6 m

$dr=0.02\times1.55m=0.031m$

$dh=0.02\times6.6m=0.132m$

$\frac{\partial V }{\partial r}=2\pi r h=2\pi \times 1.55\times 6.6=64.277$

$\frac{\partial V }{\partial h}=\pi r^2=7.5477$

Therefore, $dV=(64.277\times.031)+(7.5477\times0.132)=2.9889m$

Also, $V=\pi r^2h=49.8147m$

Hence, maximum error is given by,

$R=\frac{2.9889}{49.8147} \times 100$

= 6%

Y=x<br> y=-6x–14<br><br> (substitution method)

olga_2 [115]

Answer:

The solution is the point (-2,-2)

Step-by-step explanation:

we have

$y=x$ ----> equation A

$y=-6x-14$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$x=-6x-14$

Solve for x

$6x+x=-14\\7x=-14\\x=-2$

Find the value of y

substitute the value of x in the equation A

$y=x$

so

$y=-2$

therefore

The solution is the point (-2,-2)
