Answer:

x = 44

Step-by-step explanation:

4+4+2x+2x= 96

-(add like terms)

8+4x=96

-(subtract 8 from both sides)

4x=88

-(divide by 4 on both sides to get you x alone)

x=44

Question 3 of 10<br> Which graph shows the solution to this system of inequalities?<br> y>2x-3

belka [17]

Step-by-step explanation:

the graph should start on (-3) on the y-axis from there go up 2 and over one and that should be your next point on the graph.

you didn't show the graphs but to figure out if the color goes on the top or bottom... do

point (0,0)

plug into equation y<2x-3

(0)<2(0)-3

0<-3 (false)

wouldn't include the point (0,0)

hope this helps

Each of 100 students in the Allen School can only take 1 CSE class each, between the four classes CSE 311, CSE 312, CSE 331, and

Naddika [18.5K]

Answer:

$P(a=31,b=39,c=7,d=23) = 0.000668$

Step-by-step explanation:

Sample space, n = 100

Let the number of students signed up for CSE 311 = a

Let the number of students signed up for CSE 312 = b

Let the number of students signed up for CSE 331 = c

Let the number of students signed up for CSE 332 = d

Probability of taking CSE 311, $P_a$ = 0.3

Probability of taking CSE 312, $P_b$ = 0.4

Probability of taking CSE 331, $P_c$ = 0.1

Probability of taking CSE 332, $P_d$ = 0.2

$P(a,b,c,d) = \frac{n!}{a! b! c! d!} p_a^{a} p_b^{b} p_c^{c} p_d^{d} \\P(a=31,b=39,c=7,d=23) = \frac{100!}{31! 39! 7! 23!} * 0.3^{31} * 0.4^{39} * 0.1^{7} 0.2^{23}\\P(a=31,b=39,c=7,d=23) = \frac{4.58*10^{111}}{2.13*10^{56}* 5040 }* (1.57*10^{-55})\\P(a=31,b=39,c=7,d=23) = 0.000668$

On a coordinate grid, 1 square unit equals ¼ square mile. A rectangular walking path has vertices at (-4,5), (1,5), (-4,-5) and

dusya [7]

Answer:

<u>15 miles</u>

Step-by-step explanation:

The rectangular walking path has vertices at (-4,5), (1,5), (-4,-5) and (1,-5).

See the attached figure.

The length of the walking path = the perimeter of the rectangle

As shown, The rectangle has length of 10 units and width of 5 units

So, the perimeter = 2 ( length + width ) = 2(10+5) = 2 + 15 = 30 units

Given: 1 unit² = (1/4) mile²

so, 1 unit = √(1/4) mile = (1/2) mile

so, the the walking path = 30 units = 30 * 1/2 = 15 miles

So, the length of waking path = 15 miles
