)))))))))))))))))))

All the x - intercepts of the graph of y = (5x + 7) (2x - 1) (x - 4) will be;

⇒ - 7/5 , 1/2 , 4

What is mathematical expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The graph of the function,

⇒ y = (5x + 7) (2x - 1) (x - 4)

Now,

Find x - intercept of the equation as;

Substitute y = 0, we get;

⇒ y = (5x + 7) (2x - 1) (x - 4)

⇒ (5x + 7) (2x - 1) (x - 4) = 0

This gives three conditions as;

⇒ 5x + 7 = 0

And, 2x - 1 = 0

And, x - 4 = 0

After solve we get;

⇒ 5x + 7 = 0

⇒ x = -7/5

And, 2x - 1 = 0

⇒ x = 1/2

And, x - 4 = 0

⇒ x = 4

Hence, All the x - intercept = -7/5 , 1/2 , 4.

Therefore, All the x - intercepts of the graph of y = (5x + 7) (2x - 1) (x - 4) will be;

⇒ - 7/5 , 1/2 , 4

Suppose 65% of jurors come to a just decision. In a jury of ten people, what is the probability more than half come to a just decision? 0.7515 0.2485 0.0949 0.8374 0.9051

Answers

Answer: 0.7515

Step-by-step explanation:

Binomial probability formula:

[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex] , where

n = total number of trials.

p= probability of success in each trial.

x= Number of successes.

Let x be a binomial variable that represents the number of jurors come to just decision.

p= 0.65

n= 10

Required probability= [tex]P(x>5)=P(x=6)+P(x=7)+P(x=8)+P(x=9)+P(x=10)\\\\ =\ ^{10}C_6(0.65)^6(0.35)^4+ ^{10}C_7(0.65)^7(0.35)^3+ ^{10}C_8(0.65)^8(0.35)^2+ ^{10}C_9(0.65)^9(0.35)^1+^{10}C_{10}(0.65)^{10}(0.35)^0\\\\=0.75149550912\approx0.7515[/tex]

Hence, the probability more than half come to a just decision = 0.7515

x = 5 (please read the step by step explanation)

Step-by-step explanation:

So, I'm just going to solve for x because the instructions aren't too clear. I believe there is supposed to be an image attached to it, but seeing as I don't have that, I'll just solve for x and you can plug in with the values.

15x = 12x + 15

Same to both sides:

Isolate x:

x = 5

Just plug in those values and you'll be good to go! Have a good day!

Find the value of k, represented as a decimal rounded to the nearest tenth.

5/7 = 12/k

Answers

5/7 = 12/7
k= 16.8 .....

Answer:

We conclude that the value of k represented as a decimal rounded to the nearest tenth is:  [tex]k = 16.8[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{5}{7}=\frac{12}{k}[/tex]

We need to determine the value of k, represented as a decimal rounded to the nearest tenth.

Let us solve the expression

[tex]\frac{5}{7}=\frac{12}{k}[/tex]

Apply cross-function multiply:   if [tex]\frac{a}{b}=\frac{c}{d}[/tex]  then [tex]a\cdot \:d=b\cdot \:c[/tex]

[tex]5k=7\cdot \:12[/tex]

[tex]5k=84[/tex]          ∵ 7 · 12= 84

Divide both sides by 5

[tex]\frac{5k}{5}=\frac{84}{5}[/tex]

Simplify

[tex]k=\frac{84}{5}[/tex]

[tex]k = 16.8[/tex]    (Rounded to the nearest 0.1 or  the Tenths Place)

Therefore, we conclude that the value of k represented as a decimal rounded to the nearest tenth is:   [tex]k = 16.8[/tex]

Answer:

see explanation

Step-by-step explanation:

Consider the left side

[tex]\frac{1+sinA}{cosA}[/tex] + [tex]\frac{cosA}{1+sinA}[/tex] ← combine into a single fraction

= [tex]\frac{(1+sinA)^2+cos^2A}{cosA(1+sinA)}[/tex] ← expand and simplify numerator

= [tex]\frac{1+2sinA+sin^2A+cos^2A}{cosA(1+sinA)}[/tex] [ sin²A + cos²A = 1 ]

= [tex]\frac{1+2sinA+1}{cosA(1+sinA)}[/tex]

= [tex]\frac{2+2sinA}{cosA(1+sinA)}[/tex] ← factor out 2 on the numerator

= [tex]\frac{2(1+sinA)}{cosA(1+sinA)}[/tex] ← cancel (1 + sinA) on numerator/ denominator

-11v-14=v-14

Answers

Answer:

0.

Step-by-step explanation:

Add 14 on both sides:

-11v+0=v

So we have:

-11v=v

And there is only one number in the universe that can satisfy that and that is 0.

V = 0

-11v = v

0 = v + 11v

0 = 12v

0 = v

v = 0

14 = -2s -8
Solve for s

Answers

Answer:

s = -11

Step-by-step explanation:

14 = -2s - 8

22 = -2s

2s = -22

s = -11

14= -2s -8

+8 +8 Add 8 to both sides to isolate -2s

22= -2s

-2 -2 Divide -2 by both sides

-11=s This is the answer.

A 15-ft by 15-ft rectangular swimming pool is surrounded by a walkway of uniform width. If the total area of the walkway is 304 ft^2, how wide is the walkway?

Answers

Answer:

4 ft = width of walkway

Step-by-step explanation:

It helps if you can draw a figure.

Let x = width of walkway

Length of pool + walkway = (2x + 15)

Width of pool + walkway = (2x + 15)

area of pool and walkway together = (2x + 15)(2x + 15) = [tex]4x^{2} = 60x + 225[/tex]

Area of the pool = 15(15) = 225

Now,

The area of the walkway = area of pool and walkway together - area of pool

304 = 4[tex]x^{2}[/tex] + 60x + 225 - 225

304 = [tex]4x^{2}[/tex] + 60x

4[tex]x^{2}[/tex] + 60x - 304 = 0

4([tex]x^{2}[/tex] +15x - 76) = 0

4(x - 4)(x + 19) = 0

x = 4    x = -19

-19 must be discarded because a length cannot be negative

Therefore x = 4 ft = width of walkway
