Answer:

The function that model the number of bulbs she will plant is g = 5x²

She will plant 320 bulbs in the garden

Step-by-step explanation:

∵ Cindy’s square garden has a side length of x ft

∵ Area of the square = side × side

∴ The area of the garden = x × x

∴ The area of the garden = x² ft²

∵ She will plant 5 tulip bulbs per square foot

→ That means there are 5 tulip bulbs in 1 foot²

∵ The area of the garden is x² ft²

→ Multiply the area of the garden by 5

∴ The number of tulip bulbs in the garden = 5 × x²

∴ The number of tulip bulbs in the garden = 5x²

∵ g represents the number of bulbs she will plant in her garden

∴ g = 5x²

∴ The function that model the number of bulbs she will plant is g = 5x²

∵ The garden has a side length of 8 feet

→ That means the value of x is 8 feet

∴ x = 8

→ Substitute the value of x in the function above

∴ g = 5(8)² = 5(64)

∴ g = 320

∴ She will plant 320 bulbs in the garden

Answer:

Cosθ

Step-by-step explanation:

Given the trigonometry identity:

tan θ cot θ = 1, to transform this identity, we need to write in terms of sinθ and cosθ as shown;

In trig:

tanθ = sinθ/cosθ

cotθ = 1/tanθ

1/tanθ = 1/(sinθ/cosθ)

1/tanθ = cosθ/sinθ

Hence cotθ = cosθ/sinθ

Substitute the expression for tanθ and cotθ into the expression in question

tan θ cot θ = 1

sinθ/cosθ*cosθ/sinθ = 1

Comparing the gotten expression with

sin θ/cos θ * blank/sin θ = 1 we can dee that the blank is cosθ

Hence the correct answer is cosθ

The identity which should be filled into the blank is cos θ.

From trigonometric identities; we know;

Ultimately, sin θ/cos θ × cos θ/sin θ = 1.

Therefore, the missing identity is cos θ.

Answer:

x is 28

Step-by-step explanation:

When two lines intersected in a point, then they formed two pairs of vertically opposite angles. The vertically opposite angles are equal in measures

Let us solve our question

∵ AB and CD are straight lines intersected at O

∴ ∠AOC and ∠DOB are vertically opposite angles

∴ ∠AOD and ∠COB are vertically opposite angles

→ The vertically opposite angles are equal in measures

∴ m∠AOC = m∠DOB

∴ m∠COB = m∠AOD

→ ∠ COB is formed from ∠COE, ∠EOF, and ∠FOB

∵ m∠COB = m∠COE + m∠EOF + m∠FOB

∵ m∠COE = 3x, m∠EOF = x, m∠FOB = x + 12

∴ m∠COB = 3x + x + x + 12

→ Add the like terms

∴ m∠COB = 5x + 12

∵ m∠AOD = 152°

∵  m∠COB = m∠AOD

∴ 5x + 12 = 152

→ Subtract 12 from both sides

∴ 5x + 12 - 12 = 152 - 12

∴ 5x = 140

→ Divide both sides by 5

∴ [tex]\frac{5x}{5}=\frac{140}{5}[/tex]

∴ x = 28

→ To justify the solution substitute x by 28 in m∠COB the answer must

   be 152°

∵ m∠COB = 5x + 12

∵ x = 28

∴ m∠COB = 5(28) + 12

∴ m∠COB = 140 + 12

∴ m∠COB = 152°

∴ The value of x is correct

Answer:

  2.25

Step-by-step explanation:

The number 2.25 is already in standard form.

___

In the US (and other places), "standard form" is an ordinary decimal number, with the integer part to the left of the decimal point and the fractional part to the right of the decimal point: 2.25.

In the UK (and other places), "standard form" is a number written in scientific notation with a mantissa consisting of the leading non-zero digit to the left of the decimal point, the remaining significant digits to the right of the decimal point, and a multiplier that is 10 to the power appropriate to the place value of the leading digit. When the multiplier is 1, we need not write it.

  2.25 = 2.25×10⁰ (full form) = 2.25 (with superfluous 10⁰ removed)

Complete Question

The complete question is shown on the first uploaded image  

Answer:

a

[tex]P(X < 4) =  0.4141 [/tex]

b

[tex]P(4 < X < 6) =   0.32876[/tex]

c

 [tex]P(X >8) =  0.064037 [/tex]

d

The correct option is  B

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu =  4.5[/tex]

  The standard deviation is [tex]\sigma  =  2.3[/tex]

Generally the  probability that a randomly selected study participant's response was less than 4 is mathematically represented as

       [tex]P(X < 4) =  P(\frac{X - \mu }{\sigma} < \frac{4 - 4.5}{ 2.3}   )[/tex]

[tex]\frac{X -\mu}{\sigma} =  Z (The \  standardized \  value \  of\  X )[/tex]

So

     [tex]P(X < 4) =  P(Z < -0.217  )[/tex]

From the z-table  [tex]P(Z < -0.217  ) =  0.4141[/tex]

So

    [tex]P(X < 4) =  0.4141 [/tex]

Generally the probability that a randomly selected study participant's response was between 4 and 6 is mathematically represented as

     [tex]P(4 < X < 6) =  P( < \frac{4 - 4.5}{ 2.3}  < \frac{X - \mu }{\sigma} < \frac{6 - 4.5}{2.3})[/tex]

=> [tex]P(4 < X < 6) =  P(  \frac{4 - 4.5}{ 2.3}  < \frac{X - \mu }{\sigma} < \frac{6 - 4.5}{2.3})[/tex]

=>   [tex]P(4 < X < 6) =  P(  -0.217  < Z< 0.6522[/tex]

=>   [tex]P(4 < X < 6) =   (Z< 0.6522) -P( Z <  -0.217) [/tex]

From the z-table  

       [tex](Z< 0.6522)  = 0.74286 [/tex]

So  

       [tex]P(4 < X < 6) =  0.74286 -0.4141[/tex]

=>      [tex]P(4 < X < 6) =  0.74286 -0.4141[/tex]

=>      [tex]P(4 < X < 6) =   0.32876[/tex]

Generally the  probability that a randomly selected study participant's response was more than 8 is mathematically represented as

       [tex]P(X > 8) =  P(\frac{X - \mu }{\sigma} > \frac{8 - 4.5}{ 2.3}   )[/tex]

        [tex]P(X > 8) =  P(Z > 1.52174  )[/tex]

From the z-table  [tex]P(Z > 1.52174 ) =  0.064037[/tex]

So

    [tex]P(X >8) =  0.064037 [/tex]

Answer:

-3x= 2×2-4

Step-by-step explanation:

-3x= 4-4

-3x= 0

divide both sides by the co-efficient of x

-3x/-3= 0÷-3

x = 0

The solution of the quadratic equation 2x² + 3x − 4 = 0 will be 2.35 and negative 0.85.

Let the equation be ax² + bx + c = 0. Then the roots of the equation will be given as,

[tex]\rm x = \dfrac{-b \pm \sqrt{b^2 - 4 a c }}{2a}[/tex]

The equation is given below.

−3x = 2x² − 4

Simplify the equation, then we have

2x² − 4 = −3x

2x² + 3x − 4 = 0

Then the roots of the equation are given as,

x = [3 ± √(3² - 4 · 2 · (-4))] / (2 · 2)

x = (3 ± 6.403) / 4

x = 2.35, -0.85

The solution of the quadratic equation 2x² + 3x − 4 = 0 will be 2.35 and negative 0.85.

[tex]Mean = 4.35[/tex]

[tex]SD = 0.5655[/tex]

Step-by-step explanation:

Given

[tex]n = 5[/tex]

[tex]p = 0.87[/tex]

Solving (a): Mean

[tex]Mean = np[/tex]

[tex]Mean = 5 * 0.87[/tex]

[tex]Mean = 4.35[/tex]

Answer:

324.848

288.464

316.112

337.856

Step-by-step explanation:

Given that :

Mean (m) = 350

Standard deviation (σ) = 48

Determine the value of x for the following :

Using the z probability calculator :

a.) 70% of the values are greater than x.

1 - 0.7 = 0.3

P(x < 30%) = P(x < 0.3) = - 0.524 = z

Z = (x - m) / σ

x = (z * σ) + m

X = (- 0.524 * 48) + 350 = 324.848

b.) x is less than 10% of the values.

P(x < 0.1) = - 1.282 = z

X = (- 1.282 * 48) + 350 = 288.464

C.) 24% of the values are less than x

P(x < 0.24) = - 0.706 = z

X = (- 0.706 * 48) + 350 = 316.112

D.) x is greater than 60% of the values

P(x > 0.6) = -0.253 = z

X = (- 0.253 * 48) + 350 = 337.856

Answer:

Present age of A = 16 years

Present age of B = 12 years

Step-by-step explanation:

Let the age of B be x years.

Therefore, age of A = (x + 4) years

Four years ago:

Age of A = (x + 4 - 4) = x years

Age of B = (x - 4) years

According to the given information:

[tex] \frac{x}{x - 4} = \frac{3}{2} \\ \\ 2x = 3(x - 4) \\ \\ 2x = 3x - 12 \\ \\ 2x - 3x = - 12 \\ \\ - x = - 12 \\ \\ x = 12 \\ \\ x + 4 = 12 + 4 = 16 \\ \\ present \: age \: of \: a = 16 \: yeras \\ \\ present \: age \: of \: b = 12 \: years \\ [/tex]

Given that,

A supply of foods last for a week for 20 families.

It is required to find the time that  would the supply last for 3 more families.

20 families = 1 week = 7 days

If 3 more families joined, total no of families are now 23.

It means that,

1 family= (20/7) days

Now,

23 family =

[tex]\dfrac{20}{7}\times 23=65.71\ \text{days}\\\\\approx 66\ \text{days}[/tex]

So, the supply will last for 66 days.
