To the nearest whole percent, what is the probability that a randomly chosen member of the JV swim team does not wear glasses an

Yuri [45]

Answer: 14%

Step-by-step explanation:

Complete question is provided in the attachment below:

Probability that members of the junior varsity swim team wear glasses = 55%=0.55

Given: P(wear glasses) = 0.55

P(not wear glasses) = 1-0.55 = 0.45

P(member in 10th grade | not wear glasses) = 30%

Using conditional probability formula:

$P(B|A)=\dfrac{P(A\text{ and } B)}{P(A)}$

$\Rightarrow\ 0.30=\dfrac{P(\text{not wear glasses and in 10th grade})}{0.45}\\\\\Rightarrow\ P(\text{not wear glasses and in 10th grade})=0.45\times0.30\\\\0.135=13.5\%\approx14\%$

Hence, the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade = 14%.

So, the correct option is "14%".

Solve by elimination:

LenaWriter [7]

Answer: $(4, 3)$

Step-by-step explanation:

1) Multiply the first equation by 3,and multiply the second equation by -5: $3(2x-5y=-7)$ , $-5(5x-3y=11)$

2) Simplify: $6x-15y=-21$ , $-25x+15y=-55$

3) Add the equations to eliminate $y$ : $-19x=-76$

4) Divide both sides by $-19$ : $\frac{-19x}{19} =\frac{-76}{-19}$

5) Simplify: $x=4$

6) Substitute 4 for x in $2x-5y=-7$ : $(2)(4)-5y=-7$

7) Simplify: $-5y+8=-7$

8) Subtract $8$ on both sides of the equation: $-5y+8-8=-7-8$

9) Divide both sides by $-5$ : $\frac{-5y}{-5} =\frac{-15}{-5}$

10) Simplify: $y=3$

11) Write point: $(4, 3)$

A closed box is constructed of 4200cm2 of cardboard. The box is a cuboid, with height hcm and square base of side xcm . What is

inysia [295]

Answer:

x is 10 $\sqrt{7}$

Step-by-step explanation:

Let x is the side of the base
Let h is the height

Given that:

The area A = 4200 cm2

<=> 2 $x^{2}$ + 4xh = 4200 cm2

<=> 4xh = 4200 - 2 $x^{2}$

<=> h = (4200 - 2 $x^{2}$ )/4x

The volume of the box:

V = $x^{2}$ h

<=> V = $x^{2}$ (4200 - 2 $x^{2}$ )/4x

<=> V = (4200x - 2 $x^{3}$ )/4

To find the maximum volume, we differentiate volume with respect to x:

dV/dx = (4200 - 6 $x^{2}$ )/4

Set dV/dx = 0, we have:

4200 - 6 $x^{2}$ =0

<=> $x^{2}$ = 700

<=> x = 10 $\sqrt{7}$

We differentiate again

d²V/dx² = -12x/4

It is negative so the volume is maximum.

So x is 10 $\sqrt{7}$
