A frog in a well is 23 feet below the ground level. It jumps 16 feet and eats a fly (gross!).
How far was the fly from the ground level. Approximately.​

Answer:

The scale factor is 2.

Answer:

720

Step-by-step explanation:

As the order of the rating does not matter, we have a case of permutation.

P(6) = 6! = 6.5.4.3.2.1 = 720

Answer: 289 units

Step-by-step explanation:

Given the following :

Inventory (I) = 180

Lead time (L) = 7 days

Review time (T) = 2 weeks = 14 days

Demand (D) = 20

Standard deviation (σ) = 5

Zscore for 95% probability = 1.645

Units to be ordered :

D(T + L) + z(σT+L)

(σT+L) = √(T + L)σ²

= √(14 + 7)5²

= √(21)25

= 22.9

D(T + L) + z(σT+L) - I

20(14 + 7) + 1.645(22.9 + 7) - I

= 420 + 49.1855 - 180

= 289.1855

= 289 quantities

Steps to solve:

-4 < 11 - 3x

~Subtract 11 to both sides

-15 < -3x

~Divide -3 to both sides

5 > x

Best of Luck!

Answer:

The following are the answer to this question:

Step-by-step explanation:

In the given question the numeric value is missing which is defined in the attached file please fine it.  

Calculating the probability of the distribution for x:

[tex]\to f(x) = 0.19\ for \ x=14\\\\\to f(x) = 0.29 \ for\ x=7\\\\\to f(x) = 0.38\ for \ x=1\\\\\to f(x)=0.14 \ for \ x=0\\[/tex]

The formula for calculating the mean value:

[tex]\bold{ E(X)= x \times f(x)}[/tex]

          [tex]=14 \times 0.19+7 \times 0.29+1 \times 0.38+0\times 0.14\\\\=2.66 + 2.03+0.38+ 0\\\\=5.07[/tex]

[tex]\bold{E(X^2) = x^2 \times f(x)}[/tex]

           [tex]=14^2 \times 0.19+7^2 \times 0.29+1^2 \times 0.38+0^2 \times 0.14 \\\\=196 \times 0.19+ 49 \times 0.29+1 \times 0.38+0 \times 0.14\\\\= 37.24+ 14.21+ 0.38+0 \\\\=51.83[/tex]

use formula for calculating the Variance:

[tex]\to \bold{\text{Variance}= E(X^2) -[E(X)]^2}[/tex]

                  [tex]= 51.83 - (5.07)^2\\\\= 51.83 - 25.70\\\\=26.13[/tex]

calculating the value of standard deivation:

Standard Deivation (SD) = [tex]\sqrt{Variance}[/tex]

                                          [tex]= \sqrt{26.13} \\\\=5.111[/tex]

Answer:

13,250,000 feet or 13.25 million feet

Step-by-step explanation:

Each person in the line has a shoulder width of 1.325 feet.

For each person, there is a width of 1.325 ft. There are 10 million people.

Since:

10 million = 10,000,000

The total length must be:

[tex]1.325 * 10,000,000[/tex]

[tex]1.325 * 10,000,000 = 13,250,000[/tex]

Answer:

P (6, 3) – p (6, 4) – p (6, 2) = 270

Step-by-step explanation:

The 150 student council consist of 6 members.

Included at least one in-state student and at least one senior.

There are total 6 members: in which,

1 in- state senior,

2 in state non-senior,

1 out of state senior and

2 out of state non-senior.

Total member are 6 and we selected 3. So p (6, 3)

The way team will have only non-senior = p (6, 4)

The way team will have out of state = p (6, 2)

Subtracting the total we get:

P (6, 3) – p (6, 4) – p (6, 2) = 6x5x4 – 6 x 5 x 4 x3 – 6x 5

                                             = 30 x 4 – 30 x 12 – 30

                                             = 120 – 360 – 30

                                             =- 270

Answer:

D

Step-by-step explanation:

Let's plug 2 in for x:

18 * 2 - 35 = 36 - 35 = 1

Now, look at the answer choices:

A) Well, 1 is a whole number; it's not a fraction or a decimal. So eliminate A.

B) 1 is not a prime number; the smallest prime number is 2. So eliminate B.

C) 1 is also not a composite number; the smallest composite number is 4. So eliminate C.

D) This is true. 1 is a whole number, but it's not prime or composite, as seen above.

Thus, D is the answer.

Yes its true

Calculated value   F = 3.264 > 2.32 at 0.1 level of significance

Null hypothesis is rejected

alternative hypothesis is accepted

The population variances are not equal

Step-by-step explanation:

Step(i):-

Given first sample size 'n₁ = 13

Mean of the first sample = 59.5 min

Standard deviation of the first sample (S₁) = 7.4min

Mean of the second sample = 64.3 min

Standard deviation of the second sample( S₂ ) = 13.2min

Null hypothesis :H₀: σ₁² = σ₂²

Alternative Hypothesis : H₁ : σ₁² ≠ σ₂²

Degrees of freedom

          ν₁ = n₁ -1 = 13 -1 = 12

          ν₂ = n₂ -1 = 10 -1 = 9

Step(ii):-

Null Hypothesis  H₀ : σ₁² = σ₂²

Alternative Hypothesis : H₁ : σ₁² ≠ σ₂²

Test statistic

             [tex]F = \frac{S_{2} ^{2} }{S^{2} _{1} }[/tex]

Given sample standard deviations are given

we have to determine the Population variances  S₁² and S₂²

             n₁ s₁² = (n₁-1) S₁²

            13 ( 7.4)² = ( 13-1)  S₁²

               S₁²  = 59.32

              n₂ s₂² = (n₂-1) S₂²  

              10 ( 13.2)² = ( 10-1)  S₂²

                S₂² = 193.6

Step(iii):-

Test statistic

             [tex]F = \frac{S_{2} ^{2} }{S^{2} _{1} } = \frac{193.6}{59.3} = 3.264[/tex]

             F = 3.264

      F( 12 , 9 ) = 2.32  

Calculated value   F = 3.264 > 2.32 at 0.1 level of significance

Null hypothesis is rejected

alternative hypothesis is accepted

The population variances are not equal

Answer:

There are 16 servings

Step-by-step explanation:

First, find how many oz are in 5 quarts.

Think: In one quart there are 32 ounces, in 5 quarts how many ounces would that be?

5 x 32 = 160 ounces

Next, divide 160 ounces by 10 servings

160 / 10 = 16 servings

So there are 16 servings in a 5 quart pitcher.

Hope this helps ;)

Answer:

All real numbers are solutions.

Explanation:

−14(z − 5) = −14z + 70

[ Step 1: Simplify both sides of the equation ]

−14(z − 5) = −14z + 70

(−14)(z) + (−14)(−5) = −14z + 70 (Distribute)

−14z + 70 = −14z + 70

[ Step 2: Add 14z to both sides ]

−14z + 70 + 14z = −14z + 70 + 14z

70 = 70

[ Step 3: Subtract 70 from both sides ]

70 − 70 = 70 − 70

0 = 0

Therefore, all real numbers are solutions.

Step-by-step explanation:

Answer:

33/16

Step-by-step explanation:

x = y⁴/8 + 1/(4y²), 1 ≤ y ≤ 2

dx/dy = y³/2 − 1/(2y³)

Arc length is:

s = ∫ ds

s = ∫ √(1 + (dx/dy)²) dy

s = ∫₁² √(1 + (y³/2 − 1/(2y³))²) dy

s = ∫₁² √(1 + y⁶/4 − ½ + 1/(4y⁶)) dy

s = ∫₁² √(½ + y⁶/4 + 1/(4y⁶)) dy

s = ∫₁² ½ √(2 + y⁶ + 1/y⁶) dy

s = ∫₁² ½ √(y³ + 1/y³)² dy

s = ∫₁² ½ (y³ + 1/y³) dy

s = ½ (y⁴/4 − 1/(2y²)) |₁²

s = ½ (16/4 − 1/8) − ½ (1/4 − 1/2)

s = 33/16

the value is find the valu of y and it willl be x

Answer:

(2x +12) + (3x +23) = 180

5x + 35 = 180

5x = 145

x = 29

2(29) + 12

58 + 12

70

180 - 70 = 110

y = 110

or

3(29) + 23

87 + 23

110

corresponding angles are equal

y = 110

Answer:

X=2 or X=-6

Step-by-step explanation:

The common ratio is either 1/4 or -1/4. Since if we divide 16 by 4 we get 4 and we divide that by 4 get 1 or if we divide 16 by -4 we get -4 and that by -4 to get 1.

A more detailed math explanation:

ar^2/a=1/16

r^2=1/16

r=1/4 or -1/4

This means the second term is either 16(1/4)=4 or 16(-1/4)=-4.

So,

X+2=4 or X+2=-4

Subtract 2 on both sides:

X=4-2 or X=-4-2

X=2 or X=-6

Answer: x = 2  or   x = -6

Step-by-step explanation:

16,  x + 2,   1

Notice that a₁ to a₃ is 2 ratios.

16 · r² = 1

      r² = 1/16

      r = ± 1/4

If r = 1/4, then a₂ = 16/4

                         = 4        

                            4 = x + 2   →       x = 2

If r = - 1/4, then a₂ = 16/-4

                         = -4        

                            -4 = x + 2   →       x = -6
