So the volume is 15.84 cm The formula for the volume of a prism is given by the product of the area of the base and height of the prism. Thus, the volume of a prism can be given as V = B × H where V is the volume, B base area, and H height of the prism.

Answer:

x=1, y=3

Step-by-step explanation:

using sublimation method

y-3x=0 ....eqn(1)

2y+5x=11....eqn(2)

from eqn 1

y-3x=0

y=3x

substitute y=3x into eqn 2

2y+5x=11

2(3x)+5x=11

6x+5x=11

11x=11 (divide both sides by the coefficient of x)

x=1

since x=1 , substitute x=1 into eqn 1 to get y

y-3x=0

y-3(1)=0

y-3=0

y=3

Using elimination method

y-3x=0....eqn (1)

2y+5x=11....eqn (2)

multiply eqn 1 through by 2 and eqn 2 through by 1 to eliminate y

2y-6x=0.... eqn 3

2y+5x=11.... eqn 4

subtract eqn 4 from from eqn 3

-11x=-11 (divide both sides by the coefficient of x)

x=1

substitute x=1 into eqn 2 to get y

2y+5x=11

2y+ 5(1) =11

2y+5=11

2y=11-5

2y= 6 (divide both sides by the coefficient of y)

y=3

Step-by-step explanation:

Now when I think of solving it, I think of finding the zeros.  Now if you start with the form, for example:

[tex](x+3)(x-3)[/tex]

Then you can easily see the zeros are -3 and 3.

But if you start with the standard form:

[tex]ax^2+bx+c=0\\or\\x^2-9[/tex]

It will be harder to find the zeros and you would do the eqation or factor it.

So if your in the factored form don't go to standard to find the zeros.

The given statement is False.

An equation with highest degree two, is considered as a quadratic equation.

In standard form, the right side of an equation should be 0 and every component on the left side should be 1.

For example, x² = 4; to express this in standard form, move the number 4 to the left side of the equation, resulting in x² - 4 = 0.

If you are asked to find x in this circumstance, there is no need to write the equation in standard form; simply take this same real number of both of the equation's sides to find x.

Hence, it is not always necessary to write the quadratic equation in standard form then solve.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Part A

The probability of finding a red marble. P(red) = red / total

Total = red +  yellow +  blue

Total = 2 + 4 + 3

Total = 9

P(red) = 2/9 = 0.22222

Part B

P(blue) = blue / total

P(blue) = 3/8 = 0.375

This  means that the red marble is permanently gone. The total is different. It is eight not nine.

Part C

The probability of red followed by blue is just the answers to A and B multiplied.

P(red) followed by blue = 2/9 * 3/8

P(red) followed by blue = 0.22222 * 3.75

P(red) followed by blue = 0.0833333

If you are confident of your concellation abilities you could do this as

P(red followed by blue) = 2/9 * 3/8 = 1/3 *1/4 = 1/12 = 0.083333....

Part D

Removing the first marble had the affect of reducing the total number of marbles to 8 and the number of reds from 2 downto 1

The true statement is as follows:

The product 13 / 4 × 2 can be used to find the unit rate in cm per hour.

After one hour, the height of the candle will have decreased by 6 1 / 2 cm.

Rate is the ratio between two related quantities in different units.

The height of the candle decreases from 10 cm to 6 3 / 4 cm after burning for 1 / 2 hours.

6 3 / 4 cm = 27 / 4 cm

10 - 27 / 4 =  40 - 27 / 4 = 13 / 4 cm

Therefore, 13 / 4 cm of candles were lost in 1 / 2 hours.

Rate = 13 / 4 × 2 = 26 / 4 = 13 / 2 cm per hour

Therefore, the product 13 / 4 × 2 can be used to find the unit rate in cm per hour.

13 / 4  + 13 / 4 =   13 + 13/ 4 = 26 / 4 = 13 / 2 = 6 1 / 2 cm.

Therefore, after one hour, the height of the candle will have decreased by 6 1 / 2 cm.

Answer:

[D] 62°

Step-by-step explanation:

A right triangle = 90 degree angle

A triangle =  180 degrees

Therefore,

90 + 28 = 118

180 - 118 = 62

Hence, the measure of the other acute angle is 62

Thus, the answer is [D] 62 degree

Answer:

D. 62

Step-by-step explanation:

A point is chosen randomly on KN. The probability that the point is on KL or MN would be 11/18.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

The length of segment K L is 3 units.

The length of segment L M is 7 units.

The length of segment M N is 8 units.

The length of the segment KL + MN

KL + MN = 11

The total length of the segment KN

KL +LM + MN

3 + 7 + 8 = 18

SO, The probability that the point is on KL or MN = 11/18

Using the t-distribution, it is found that the 95% confidence interval for the population mean is (1413.18, 1564.82).

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 65 - 1 = 64 df, is t = 1.9977.

The parameters of the interval are given as follows:

[tex]\overline{x} = 1489, s = 306, n = 65[/tex].

Hence, the bounds of the interval are given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 1489 - 1.9977\frac{306}{\sqrt{65}} = 1413.18[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 1489 + 1.9977\frac{306}{\sqrt{65}} = 1564.82[/tex]

The 95% confidence interval for the population mean is (1413.18, 1564.82).
