Gemiola [76]

Answer:

the answer should be 1/11

Step-by-step explanation:

p(blue first) = 3/12

p(yellow second) = 4/11

so p = 3/12 x 4/11

1/11 is your probability

(PLEASE ANSWER!!) a college student completed some courses worth 4 credits and some courses worth 3 credits. the student earned

Ierofanga [76]

The college student took 13 courses of 3 credit hours.

Step-by-step explanation:

Given,

Total credits = 59

Total courses = 18

Let,

Number of 3 credit hour courses = x

Number of 4 credit hour courses = y

According to given statement;

x+y=18 Eqn 1

3x+4y=59 Eqn 2

We will eliminate y to find the number of 3 credit hour courses, therefore,

Multiplying Eqn 1 by 4

$4(x+y=18)\\4x+4y=72\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(4x+4y)-(3x+4y)=72-59\\4x+4y-3x-4y=13\\x=13$

The college student took 13 courses of 3 credit hours.

The amount sean makes each day depends on how much he works. Write an equation that represents the total, T, Sean makes each day

tankabanditka [31]

H x r = T The number of hours Sean works is represented by (h), Sean gets paid (r) per hour. By multiplying the number of hours worked by the rate per hour you get the total amount Sean gets paid (T)

<h3>Answer:</h3>

$\large\boxed{\pink{\sf \leadsto Value \ of \ LM \ is \ 11 \ units . }}$

<h3>Step-by-step explanation:</h3>

A figure is given to us in which we can see two triangles one is ∆ MPL and other is ∆MPN .

Figure :- 

$\setlength{\unitlength}{1 cm}\begin{picture}(12,12)\linethickness{0.25mm}\put(0,0){\line(1,2){2}} \put(0.001,0){\line(1,0){4}}\put(2,0){\vector(0,1){5}}\put(4,0){\line( - 1,2){2}}\put(0,-0.4){$\bf L $}\put(2,-0.4){$\bf P$}\put(4,-0.4){$\bf N $}\put(2.2,4){$\bf M $}\put(2.8, - .4){$\bf 5 $}\put(1, - .4){$\bf 5 $}\put(3.4, 2){$\bf 11 $}\put(2.3,0){\line(0,1){.3}}\put(2.3,.3){\line( - 1,0){.3}}\end{picture}$

$\underline{\blue{\sf In\: \triangle MPL \ \& \ \triangle MPN :- }}$

$\qquad \bullet LP = PN = 5 \:\:(given) \\\\\qquad \bullet MP = MP \:\:(Common) \\\\\qquad \bullet \angle MPN = \angle MPL = 90^{\circ} \:\: (given)$

Hence by SAS congruence condition ,

$\orange{\bf \triangle MPL \cong \triangle MPN }$

Hence by cpct ( Corresponding parts of congruent triangles ) we can say that , LM = NM = 11 units .

<h3>Hence the value of LM is 11 units .</h3>

A pool a possible candidate for a student council consists of 14 freshmen and 8 softwares how many different councils consisting

Andreas93 [3]

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.

We have given that,

A pool of possible candidates for a student council consists of 14 freshmen and 8 software.

We have to determine the how many different councils consisting of 5 freshmen and 7 sophomores are possible

<h3>What is the combination?</h3>

$_n C_r=\frac{n !}{r ! (n-r) !}_n C_r = number of combinations\\\n = total number of objects in the set\\\r = number of choosing objects from the set$

The total number of the council is

$_{10} C_5\times _9 C_7$

=252(36)

=9216

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.
