Answer:

The third quartile would be <u>39</u>.

Step-by-step explanation:

• Since the numbers are already in order, the next step would be to find the median:

- The <u>median</u> is the middle number; found by ordering all data points and picking out the one in the middle.

  • The median would be 29.

• The <u>first quartile</u>, is denoted as Q1 and is the middle number that falls between the smallest value of the data set and the median.

  • The first quartile would be 24.

• The <u>third quartile</u>, is denoted as Q3 and is the median of the upper half of the data set.

  • The third quartile would be 39.

For what values of m does the graph of y = 3x^2 + 7x + m have two x-intercepts? a) m&gt;12/49 b) m&lt;12/49 c) m&lt;49/12 d) m&g

The quadratic formula, has a part we call the "discriminant" defined by the variables that are inside the square root, and is denotated by "delta":

<span>Δ=<span>b2</span>−4ac</span> Whenever we solve a quadratic equation that is complete and we analyze the discriminant, we can get 3 scenarios: <span>if→Δ>0<span>=></span>∃<span>x1</span>,<span>x2</span>/a<span>x2</span>+bx+c=0</span> This just means: "if the discriminant is greater than zero, there will exist two x-intercepts" And for the second scenario: <span>if→Δ=0→∃<span>xo</span>/a<span>x2</span>+bx+c=0</span> This means: "if the discriminant is equal to zero, there will be one and only one x-intercept" And for the last scenario: <span>if→Δ<0→∃x∉R/a<span>x2</span>+bx+c=0</span> This means that :"if the discriminant is less than zero, there will be no x-intercepts" So, if we take your excercise and analyze the the discriminant: <span>3<span>x2</span>+7x+m=y</span> we will find the values that satisfy y=0 : <span>3<span>x2</span>+7x+m=0</span> And we'll analyze the discriminant: <span>Δ=<span>72</span>−4(3)(m)</span> And we are only interested in the values that make the discriminant equal zero: <span><span>72</span>−4(3)(m)=0</span> All you have to do is solve for "m".

a cone has a circular base with a diameter of 18 inches. the height of the cone is 40 inches what is the approximate lateral are
lana66690 [7]

Lateral Area of cone=1130.4 inches^2

Step-by-step explanation:

Diameter of circular base = 18 inches

Height of cone = 40 inches

Lateral Area of cone = ?

The formula used to find Lateral Area of cone is:

Lateral\,\,Area\,\.of\,\,cone=\pi rh

Since we know that r= d/2,

so, r = 18/2

r= 9

Putting values, we get:

Lateral\,\,Area\,\,of\,\,cone=\pi rh\\Lateral\,\,Area\,\,of\,\,cone=\pi *9*40\\Lateral\,\,Area\,\,of\,\,cone=1130.4 inches^2

So, Lateral Area of cone=1130.4 inches^2

Find the a26 arithmetic sequence: -15,-35,-55,-75<br> -515 <br> 460 <br> -490
Vlad [161]

Step-by-step explanation:

<h3><u>QU</u><u>ESTION</u><u>:</u><u>-</u></h3>

<u>Fin</u>d 26th term of the A.P --15,-35,-55,-75...

<h3><u>Solu</u><u>tion</u><u>:</u><u>-</u></h3>

First term=a=-15

Common Difference=d=-20

We know that

\boxed{\sf a_n=a+(n-1)d}

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+(26-1)(-20)

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+25(-20)

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+(-500)

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15-500

\\ \:\:\:\:\sf {:}\dashrightarrow {\boxed{\bf a_{26}=-515}}

39.99a+45=44.99+.40a
klasskru [66]

the first step is to isolate A which gets 39.59a+45=44.99

now get A and only A

39.59a=-.1

now divide both sides by 39.59 getting A= -0.00252589
