This is a 30° 60° 90° triangle, so the rules below apply:

x is the short leg of the triangle, located across from the 30° angle. (In this problem, the short leg is labled b)

The hypotenuse leg is across from the right angle, and is always 2x (In this problem, the hypotenuse leg is labled c)

The long leg of the triangle is located across the 60° angle and is always x√3. (in this problem, the long leg is labeled a)

Answer:

2

Step-by-step explanation:

First off, the slope of f(x) is -4.  It is in the form y=mx+b and m=-4.

For g(x), the slope can be calculated from any two points given.  I willuse (1,9) and (3,21) because I like positive numbers.  So, slope is rise over run and it is calculated from (y1-y0)/(x1-x0)  This gives me (21-9)/(3-1) which is equal to 6.  So adding the two slopes: 6+ (-4)=2

Answer: look down below

Step-by-step explanation:

BEFORE

91+87+100+88+95+91=552

552\6=92

Median=92

the 6 is how much data points we have

AFTER

91+87+100+88+95+91+98+100+88+86=924

924/10=92.4

the 10 represnts how many data points we have now

MEDIAN=92.4

the median will be increased by 0.4

Answer:1/3

Step-by-step explanation:

He gave away 2/6 of the erasers. You can simplify that by doing 2 divided by 2 6 divided by 2 which makes it 1/3. Daniel gave away 1/3 of the erasers.

Answer:

1/3

Step-by-step explanation:

he gave one to p.j=1/6

he gave one to Ken=1/6

1/6 +1/6=2/6=1/3

h(x) = 5 - 9x

h(8) = 5 - 9×8 ( putting value x = 8)

h(8) = 5 - 72

h(8) = -67

Answer is -67.

Answer:

h(8) = -67

Step-by-step explanation:

To solve this problem, we take x in h(x) and input it for x within the problem.

In this case, h(8), so 8 is replacing x in 5-9x.

h(8) = 5 - 9(8)

h(8) = 5 - 72

h(8) = -67

Answer:

The margin of error will be "0.65". A further explanation is provided below.

Step-by-step explanation:

The given values are:

n = 343

x = 110

At 99% confidence level,

[tex]\alpha = 1-99[/tex]%

  [tex]=1-0.99[/tex]

  [tex]=0.01[/tex]

then,

[tex]\frac{\alpha}{2} =\frac{0.01}{2}[/tex]

  [tex]=0.005[/tex]

or,

[tex]Z_{\frac{\alpha}{2} }=Z_{0.005}[/tex]

     [tex]=2.576[/tex]

Now,

The point estimate will be:

⇒  [tex]\hat{P}=\frac{x}{n}[/tex]

⇒      [tex]=\frac{110}{343}[/tex]

⇒      [tex]=0.321[/tex]

or,

⇒  [tex]1-\hat{P}=1-0.321[/tex]

⇒            [tex]=0.679[/tex]

The margin of error will be:

⇒  [tex]E=Z_{\frac{\alpha}{2} }\times \sqrt (\frac{(\hat{P}\times (1 - \hat{P})) }{n} )[/tex]

On substituting the above values, we get

⇒      [tex]=2.576\times \sqrt{\frac{0.321\times 0.679}{343} }[/tex]

⇒      [tex]=2.576\times \sqrt{\frac{0.217959}{343} }[/tex]

⇒      [tex]=0.065[/tex]

hence,

⇒  [tex]\hat{P}-E<p<\hat{P}+E[/tex]

⇒  [tex]0.321-0.065<p<0.321+0.065[/tex]

⇒  [tex]0.256,0.386[/tex]

Answer:

60

Step-by-step explanation:

If  Isabelle sells 150 out of 250 ears of corn. Then the percentage of the ears of corn she sold will be 60%.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Every morning she starts with 250 ears of corn.

On Saturday, Isabelle sells 150 out of 250 ears of corn.

Then the percentage of the ears of corn she sold will be

[tex]\rm P = \dfrac{150}{250} \times 100\\\\P = 15 \times 4\\\\P = 60 \%[/tex]

Answer:

★ Given :

Cost of 50 chickens and 30 ducks = $ 550

Cost of 44 chickens and 36 ducks = $ 532

★ To find :

Cost of chicken and duck

★ Solution :

Assume :

Cost of chicken = x

Cost of duck = y

According to question :

50x + 30y = 550 ......(1)

44x + 36y = 532......(2)

1) - (2)

(50x + 30y) - (44x + 36y) = 550 - 532

50x + 30y - 44x - 36y = 18

6x - 6y = 18

6(x - y) = 18

x - y = 18/6

→ x - y = 3 ....(3)

In equation 1 ,

50 x + 30y = 550

taking 10 common

10(5x + 3y) = 550

5x + 3y = 550/10

5x + 3y = 55

by taking 3 common

3(5/3 x + y) = 55

by dividing 3 on both sides

5/3x + y = 55/3 .....(4)

(3) + (4)

x - y + 5/3 x + y = 3 + 55/3

x + 5/3 x = 64/3

8/3 x = 64/3

by multiplying 3 on both sides

8x = 64

x = 64/8

→ x = 8

→ Cost of chicken = $ 8 ..

by putting value of x in equation 3

x - y = 3

8 - y = 3

y = 8 - 3

→ y = 5

→ Cost of ducks = $5..
