JONAS HAS A FILE CABINET IN THE SHAPE OF A right rectangular prism. the area of the base of the file cabinet is 450 square inche

Nostrana [21]

The volume of a rectangular prism can be found by the formula:
V = A × h

Where:
A = area of the base of the prism
h = height of the prism

Therefore:
V = 450 × 53
= 23850 in³

The volume of the file cabinet is <span>23850 in³.</span>

11.Find the missing value given the rate of change.(2,6) and (x, 10) m = 4

Anvisha [2.4K]

The missing value x=3 is obtained by the concept of slope in coordinate geometry.

<h3>What is slope?</h3>

Positive or negative rates of change are both possible. Since the slope of a line is determined by the ratio of the vertical and horizontal change between any two locations on a plane or line, the slope is determined by the rise to run ratio. Where, Rise is the difference in elevation between two points. The horizontal shift between two places is known as a run.

Formula of slope = $\frac{y2-y1}{x2-x1}$ (equation 1)

According to the question the coordinates are: xi=2, x2=x, y1=6, y2=10

Given, rate of change=4 (here rate of change=slope)

Putting all coordinates in equation 1

Slope= $\frac{10-6}{x-2}$

4=4/x-2

x-2=1

x=3

Therefore, the missing value x=3

Help FAST PLZ!!! marking brainliest!

ss7ja [257]

Answer:

After finding the prime factorization of $2010=2\cdot3\cdot5\cdot67$, divide $5300$ by $67$ and add $5300$ divided by $67^2$ in order to find the total number of multiples of $67$ between $2$ and $5300$. $\lfloor\frac{5300}{67}\rfloor+\lfloor\frac{5300}{67^2}\rfloor=80$ Since $71$,$73$, and $79$ are prime numbers greater than $67$ and less than or equal to $80$, subtract $3$ from $80$ to get the answer $80-3=\boxed{77}\Rightarrow\boxed{D}$.

The theoretical probability that Chandra will be chosen as one of the science fair participants is 0.8 or 80%.

<h3>What is theoretical probability?</h3>

Theoretical probability of an event is the ratio of number of favourable outcome to the total expected number of outcome of that event.

Five students, Adriana, Ben, Chandra, Diana, and Ernesto, would each like one of the four spots at the regional science fair.

Their names are placed in a hat, and four names are chosen at random to decide who attends the fair.

The total number of names are 5.
The total number of names chosen are 4.

The total number of ways 4 names can be taken out from 5 names is,

$^5C_4$ .

Here one spot needs to be fixed for Chandra. Now the total number of outcome remain 4 and favourable outcome remain 3.

Thus, the number of ways 4 names can be taken out such that it contains the name Chandra is

$^4C_3$ .

The theoretical probability that Chandra will be chosen as one of the science fair participants is,

$P=\dfrac{^4C3}{^5C4}\\P=\dfrac{4}{5}\\P=0.8\\P=80\%$

Thus, the theoretical probability that Chandra will be chosen as one of the science fair participants is 0.8 or 80%.
