Naddika [18.5K]3 years ago
8 0

Answer:

Step-by-step explanation:

first lets meake the minutes into hours by dividing our minutes into hours

6300 / 60 = 105

so in total they go 105 hours in 15 days (5 days for 3 weeks is 15 days)

to find how many hours in each day lets divide our hours into the 5 days

105 / 15 = 7 hours a day

hope this helps <3

"Sketch a possible graph for a negative Quintic polynomial with one real zero." Can anyone explain how this is done? And if poss
Sidana [21]

quintic means degree of 5.

a negative quintic would be: f(x) = -x⁵ <u>+              </u>

an example with one real zero could be: -x⁵ + x³ + x + 3   (see attachment)

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Check all that apply.
DIA [1.3K]
Reta a:

3x-4y=7 \\ -4y=-3x+7 \\ 4y=3x-7 \\ y= \frac{3}{4}x- \frac{7}{4}

reta x:

y=ax+b

Retas paralelas possuem coeficientes angulares iguais ⇒ mₐ=mₓ

y= \frac{3}{4}x+b

(-4,-2)

\frac{3}{4}.(-4)+b=-2 \\ -3+b=-2 \\ b=-2+3 \\ b=1

∴ y=3/4x+1

Suppose that you have 11 cards. 5 are green and 6 are yellow. The 5 green cards are numbered 1, 2, 3, 4, and 5. The 6 yellow car
Ivanshal [37]

Answer:

a. S={G1,G2,G3,G4,G5,Y1,Y2,Y3,Y4,Y5,Y6}

b. P(G)=5/11

c. P(G/E)=2/5 or 0.4

d. P(G and E)=2/11 or 0.1818

e. P(G or E)=8/11 or 0.7273

f. G and E not mutually exclusive

Step-by-step explanation:

G={G1,G2,G3,G4,G5}

n(G)=5

Y={Y1,Y2,Y3,Y4,Y5,Y6}

n(Y)=6

E={G2,G4,Y2,Y4,Y6}

n(E)=5

a)

The possible outcomes in sample space are

S={G1,G2,G3,G4,G5,Y1,Y2,Y3,Y4,Y5,Y6}

b)

P(G)=n(G)/n(S)=5/11

c)

P(G/E)=P(G and E)/P(E)

G and E={G2,G4}

n(G and E)=2

P(G and E)=n(G and E)/n(S)=2/11

P(E)=n(E)/n(S)=5/11

P(G/E)=2/5

d)

G and E={G2,G4}

n(G and E)=2

P(G and E)=n(G and E)/n(S)=2/11

e)

P(G or E)= P(G)+P(E)-P(G and E)

P(G or E)=5/11+5/11-2/11

P(G or E)=8/11

f)

G and E are not mutually exclusive because G and E have 2 outcomes in common.

G and E={G2,G4}

Thus, P(G and E)≠0 and G and E are not mutually exclusive events

Y = – 3
KonstantinChe [14]

The  best approximation for the solution to this system of equations is (-2.2,-3)

Option C is correct.

Step-by-step explanation:

Solving the system of equations to get the exact value of x:

y = -3\\y = x-0.8

Let

y = -3\,\,eq(1)\\y = x-0.8\,\,eq(2)

Putting value of y from eq(1) into eq(2)

-3=x-0.8

x=-3+0.8

x=-2.2

So, Value of x is -2.2

The  best approximation for the solution to this system of equations is:

x=-2.2 and y = -3

(-2.2,-3)

Option C is correct.

Volume of a cone formula: πr^2(h/3)

r = 4, h = 10

Equation:

π(4^2)(10/3)

= π(16)(3.333333)

= 167.551608
