Answer:

true

Step-by-step explanation:

Answer:

The correct option is;

[tex]\overline{YZ}\left | \right | \overline{AC}[/tex]

Step-by-step explanation:

The dimensions given are;

YX = 2 × AX (A = midpoint of YX)

ZX = 2 × CX (C = midpoint of ZX)

∠X and ∠X are congruent (Reflexive property)

Therefore, triangle XAC is similar to triangle XYZ (SAS similarity theorem)

Since ∠XYZ = ∠XAC segments YZ and AC are parallel from having equal angle on the same  side of the transversal YX

Therefore the correct option should be;

[tex]\overline{YZ}\left | \right | \overline{AC}[/tex]

Answer:ΔBCZ ≅ ΔYAB

Step-by-step explanation: since we know the midpoint are <ABC we can see the that answer is correct.

Answer:

After five hours, there will be 40 mg of caffeine remaining in the blood.

After 10 hours, 20 mg.

After only one hour, about 69.64 mg.

And after two hours, about 60.63 mg.

Step-by-step explanation:

We are given that one-half of the caffeine in the bloodstream is eliminated every five hours.

We are also given that the initial amount is 80 mg.

Using this information, we can write the following function:  

[tex]\displaystyle f(x)=80\left(\frac{1}{2}\right)^{\dfrac{x}{5} }[/tex]

Where x is the number of hours that has passed.

Using this function, we can evaluate for f(5), f(10), f(1), and f(2).

They evaluate to:

[tex]f(5)=40[/tex]       [tex]f(10)=20[/tex]       [tex]f(1)\approx 69.6440[/tex]     [tex]f(2) \approx 60.6287[/tex]

So, after five hours, there are 40 mg of caffeine remaining in the blood.

After 10 hours, 20 mg of caffeine.

After only one hour, about 69.64 mg.

And after two hours, about 60.63 mg.

Answer:

x=83

Step-by-step explanation:

97+x=180

x=83

Answer:

∠x = 83°

Step-by-step explanation:

Since ∠x and ∠y are supplementary ∠s so they add up to 180°

So,

∠x + ∠y = 180

Where ∠y = 97°

∠x + 97° = 180

∠x = 180-97

∠x = 83°

Answer:

k = ⅕  

Step-by-step explanation:

The slope-intercept equation for a straight line is

y = mx + b, where

m = the slope and

b = the y-intercept

Data:

(3,4)     = a point on the line

(3k,0)   = x-intercept

(0,-5k) = y-intercept

Calculations:

1. Slope

m = (y₂ - y₁)/(x₂ - x₁) = (-5k - 0)/(0 - 3k) = -5/(-3) = ⁵/₃

This makes the equation

y = ⁵/₃x - 5k

2. k

Insert the value of the known point: (3,4)

4 = (⁵/₃)(3) - 5k

4 = 5 - 5k

-1 = -5k

k = ⅕

The figure below shows your graph passing through (3,4) with intercepts 3k and -5k on the x- and y-axes respectively .

Step-by-step explanation:

Amount of oranges:

Oranges sold:

Money made:

Selling price of 150 kg:

Cost price:

Answer:

Rs64.00/kg  

Step-by-step explanation:

1. Calculate the amount of good oranges

Total amount of oranges    = 150 kg

Amount of rotten oranges =    18 kg

Amount of good oranges    = 132 kg

2. Calculate the income from  the good oranges

[tex]\text{Income} = \text{132 kg} \times \dfrac{\text{Rs80}}{\text{1 kg}} = \text{Rs10 560}[/tex]

3. Calculate the net unit rate of income

The income from the good oranges was Rs10 560.

Based on 150 kg of oranges, the unit rate of income was

[tex]\text{Unit rate of income} = \dfrac{\text{RS10 560}}{\text{150 kg}} = \text{Rs70.40/kg}[/tex]

4. Calculate the original unit rate of cost

Let x = original unit cost. Then

0.10x = 10 % of original unit cost and

1.10x = 10 % over original unit cost

1.10x = RS70.40/kg

        x = (RS70.40/kg)/1.10 = Rs64.00/kg

The original unit rate of cost was Rs64.00/kg.

Answer: 45°

Step-by-step explanation:

Given that :

∠A=5x−15°---(1)

∠B=2x+21°----(2)

Equating

∠A = ∠B

(5x−15)° = (2x+21)°

5x - 15 = 2x + 21

Collecting like terms

5x - 2x = 21 + 15

3x = 36

x = 12

Substitute x = 12 in either angle A or B since both are congruent

∠A=(5x−15)°

∠A = (5(12) - 15)°

∠A = (60 - 15)°

∠A = 45°

∠A = ∠B = 45°

Answer:

n = 20

Step-by-step explanation:

4n + 14 - 5n = -6

(4n - 5n) + 14 = -6      Combine like terms

-n + 14 = -6

    -14    -14                Subtract 14 from both sides

-n = -20

/-1    /-1                        Divide by -1

n = 20

Answer:

n = 20

Step-by-step explanation:

[tex]4n+14-5n=-6[/tex]

So we have to simplify the equation.

4n + -5n = -n

So our equation looks like this now -> [tex]-n+14=-6[/tex].

So now to get -n by itself we get 14 and -6 by itself.

So we do -6 - 14 and we get -20.

So our equation looks like [tex]-n=-20[/tex].

So now we have to make n positive we do -n ÷ -1 which is n.

And since we divided -n by -1 we have to divide -20 by -1 which is 20.

So n is 20.

Answer:

[tex]0.81 - 2.326 \sqrt{\frac{0.81(1-0.81)}{131}}=0.730[/tex]

[tex]0.81 + 2.326 \sqrt{\frac{0.81(1-0.81)}{131}}=0.890[/tex]

And the confidence interval would be:

[tex] 0.730 \leq \p \leq 0.890[/tex]

Step-by-step explanation:

Information given:

[tex] n=131[/tex] represent the sample size

[tex] \hat p=0.81[/tex] represent the estimated proportion

The confidence interval would be given by this formula

[tex]\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

For the 98% confidence interval the value of [tex]\alpha=1-0.98=0.02[/tex] and [tex]\alpha/2=0.01[/tex], with that value we can find the quantile required for the interval in the normal standard distribution.

[tex]z_{\alpha/2}=2.326[/tex]

And replacing into the confidence interval formula we got:

[tex]0.81 - 2.326 \sqrt{\frac{0.81(1-0.81)}{131}}=0.730[/tex]

[tex]0.81 + 2.326 \sqrt{\frac{0.81(1-0.81)}{131}}=0.890[/tex]

And the confidence interval would be:

[tex] 0.730 \leq \p \leq 0.890[/tex]

Answer:

y= 2/3x + 2

Step-by-step explanation:

Answer:

y = 2/3x − 2.

Step-by-step explanation:

We essentially just want a  y  on the left side, so let's subtract 2x from both sides to get  −3y = −2x + 6.

Lastly, let's divide both sides by −3 to get y = 2/3x − 2.

Our equation is now in slope-intercept form, where the slope is 2/3 and our y-intercept is −2.

The formula for calculating the standard deviation of sample data is expressed as    [tex]\sigma=\sqrt{\frac{\sum(x_1-\overline x)^2+(x_2-\overline x)^2+...(x_n-\overline x)^2)}{N} }[/tex]

The standard deviation is a measure of the amount of variation or dispersion of a set of values.

A lower value of the standard deviation shows that value is close to the mean otherwise it is far from the mean

The formula for calculating the standard deviation of sample data is expressed as:

[tex]\sigma=\sqrt{\frac{\sum(x_1-\overline x)^2}{N} }[/tex]

Assume we have the following data x1, x2, ....xn, the standard deviation will be given as:

Answer:

[tex]x^2 = -16y[/tex]

Step-by-step explanation:

Given

[tex]Vertex = (0,0)\\Focus = (0,-4)[/tex]

Required

Equation of the parabola (in standard form)

The standard form of a parabola is [tex](x - h)^2 = 4p (y - k),[/tex]

Such that

Vertex = (h,k)

Focus = (h, k + p)

For the vertex

This implies that (h,k) = (0,0)

h = 0 and k = 0

For the focus

This implies that (h, k + p) = (0, -4)

[tex]h = 0\\k + p = -4[/tex]

Recall that [tex]k = 0;[/tex]

Hence, [tex]0 + p = -4[/tex]

[tex]p = -4[/tex]

Substitute [tex]p = -4[/tex], [tex]h = 0\ and\ k = 0[/tex] in the given formula

[tex](x - h)^2 = 4p (y - k),[/tex] becomes

[tex](x - 0)^2 = 4 * -4 (y - 0),[/tex]

[tex](x)^2 = 4 * -4 (y),[/tex]

[tex]x^2 = -16 (y),[/tex]

[tex]x^2 = -16y[/tex]

Hence,, the standard form is [tex]x^2 = -16y[/tex]

Answer: 2,369.25 cm3

Step-by-step explanation:

Hi, to answer this question we have to use proportions:

X has volume of 64 cm3 and s surface area of 208 cm2

The proportion is = volume / surface area = 64/208

Y has volume of 729 cm3

Volume / surface area = 729/ s (surface area of y)

64/208 = 729/ s

Solving for s:

s = 729 / (64/208)

s = 2,369.25 cm3

Answer:

there is one possible value: 0.

Step-by-step explanation:

We have 10 different letters in this fraction {G,R,O,U,N,D,B,A,S,E} and only 10 different digits {0,1,2,3,4,5,6,7,8,9}. It means that some letter must be equal to 0. Consider two cases:

I case:

[tex]0 \in \{G, R, O, U, N, D\}[/tex]. Then enumerator of fraction must be equal to zero (because product of numbers with zero among them always zero).

So [tex]\frac{GROUND}{BASE} = \frac{0}{BASE} = 0[/tex] in this case.

II case:

[tex]0 \in \{B,A,S,E\}[/tex]. Then for the same reasons as in I case denominator of fraction is equal to zero. And we know that fraction

[tex]\frac{BASE}{0}[/tex] is not well-defined.
