Answer:A

Step-by-step explanation:

Answer: D (12)

Step-by-step explanation: I put both equations into desmos and the coordinates are (12,23) and x=12. It's not 6!

Answer: x + 2 + 4 = 25

x = 19

Step-by-step explanation:

First, you would solve The word problem with the equation 25 - 2 - 4, which equals 19, then you essentially flip the equation around, but instead of 19, you have x. when you do this it’s important to flip the operation you use too, so if the original equation uses subtraction, switch it to addition, and vise versa. The end result would be x + 2 + 4 = 25.

D

Step-by-step explanation:

there are 4 jumps. and 3 numbers between the jumps

Given:

Length of a rectangular piece of fabric, l = 24 inches

Width, w = 40 inches

Leanna folds the piece of fabric along its diagonal to form a triangular scarf.

To find:

The area of the triangular scarf.

Solution:

Area of the rectangular piece of fabric is

[tex]Area=length\times width[/tex]

[tex]Area=24\times 40[/tex]

[tex]Area=960[/tex]

Area of rectangular piece of fabric is 96 sq. inches.

We know that diagonal of a rectangle divides the rectangle in two equal parts.

Leanna folds the piece of fabric along its diagonal to form a triangular scarf. So, area of triangular scarf is half of area of rectangular piece of fabric.

[tex]\text{Area of triangular scarf}=\dfrac{1}{2}\times 960[/tex]

[tex]\text{Area of triangular scarf}=480[/tex]

Therefore, the area of triangular scarf is 480 sq. inches.

Answer:

86

Step-by-step explanation:

angle NOP and angle POQ add up to create angle NOQ which equals 123 degrees.  We just have to subtract 123-37 (NOP) to find the measure of angle POQ which equals 86 degrees

Answer:

The measure of angle ABD is 86 degrees.

Answer:

The value is [tex]n = 2887[/tex]

Step-by-step explanation:

From the question we are told that

  The population proportion is  [tex]p = 0.54[/tex]

   The margin of error is  [tex]E = 1.5 \% = 0.015[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the sample size is mathematically represented as

           [tex]n = [\frac{Z_{\frac{\alpha }{2} } }{E} ]^2 * p(1-p)[/tex]

=>        [tex]n = [\frac{1.645 }{0.015} ]^2 * 0.54(1-0.54)[/tex]

=>        [tex]n = 2887[/tex]

Answer:

46.7

Step-by-step explanation:

3% of light is obliterated from this pane of glass

1-0.03

= 97% = 0.97

The function has been given as

P(n) = 100(0.97)^x

Let's take our x to be 25 just as the question says

P(n) = 100(0.97)²⁵

P(25) = 46.697

This is approximately equal to 46.7

Therefore the percentage of light that would pass through 25 panes is 46.7

Answer: a) Let x be a random variable that represents the number of brown M&M’s in a milk chocolate packet.

b) Mean =7.28

c) Variance = 6.2608

d) Standard deviation = 2.5022

Step-by-step explanation:

Given : The proportion of brown M&M’s in a milk chocolate packet is approximately : p=14% =0.14

We have outcomes for every randomly selection : 1) its in a milk chocolate packet 2) its not.

a) Let x be a random variable that represents the number of brown M&M’s in a milk chocolate packet.

So x follows binomial distribution.

b) Sample size : n=52  (given)

Mean [tex]= np = (0.14)(52) =7.28[/tex]

c) Variance = [tex]n p (1-p)= 52 (0.14)(1-0.14) =7.28(0.86)=6.2608[/tex]

d) Standard deviation =[tex]\sqrt{Variance}=\sqrt{6.2608}\approx2.5022[/tex]

Answer:

0.2657

Step-by-step explanation:

Given that:

Probability of Error (p) = 1/ 1000 = 0.001

Number of trials (n) = 10000

μ = (n * p) = 10000 * 0.001 = 10

Using the binomial distribution :

P(x, μ) = e^-μ (μ^x) / x!

for x = 6

P(6, 10) = e^-10 (10^6) / 6!

P(6, 10) = 0.0000453999 (1388.8888) = 0.06305541263112

for x = 7

P(7, 10) = e^-10 (10^7) / 7!

P(7, 10) = 0.0000453999 (1984.1269) = 0.09007916284731

for x = 8

P(8, 10) = e^-10 (10^8) / 8!

P(8, 10) = 0.0000453999 (2480.1587) = 0.11259895696413

P(6) + P(7) + P(8)

0.06305541263112 + 0.09007916284731+ 0.11259895696413

= 0.26573353244256

= 0.2657

Answer:

[tex]\dfrac{800 \pi}{7} \ miles/min[/tex]

Step-by-step explanation:

From the given information:

We learned that the light rotates 8 revolutions per minute.

Therefore;

[tex]\dfrac{d \theta}{d t}= \dfrac{8 * 2 \pi}{1 \ min}[/tex]

[tex]\dfrac{d \theta}{d t}= 16\pi \ rads/min\\[/tex]

From the trigonometry formula, the tanget of the lighthouse in relation to the  closest point on a straight shoreline can be expressed as:

[tex]tan \theta = \dfrac{x}{7}[/tex]

By differentiation with respect to t; we have:

[tex]\dfrac{d(tan \theta)}{dt} = \dfrac{1}{7} * \dfrac{dx}{dt}[/tex]

[tex]\dfrac{d(tan \theta)}{d \theta}* \dfrac{d \theta}{dt} = \dfrac{1}{7} * \dfrac{dx}{dt}[/tex]

By applying the chain rule:

[tex]sec^2 * \dfrac{d \theta }{d t} = \dfrac{1}{7} * \dfrac{dx}{dt}[/tex]

[tex](1 + tan ^2 \theta) \dfrac{d \theta }{dt} = \dfrac{1}{7} * \dfrac{dx}{dt}[/tex]

When x = 3 ; we have [tex]tan \theta = \dfrac{1}{7}[/tex]

[tex]\bigg (1 + \dfrac{1}{49} \bigg ) \dfrac{d \theta }{dt} = \dfrac{1}{7} * \dfrac{dx}{dt}[/tex]

Also;

[tex]\dfrac{d \theta}{d t}= 16\pi \ rads/min\\[/tex]

[tex]\bigg (1 + \dfrac{1}{49} \bigg ) 16 \pi = \dfrac{1}{7} * \dfrac{dx}{dt}[/tex]

[tex]\bigg ( \dfrac{50}{7} \bigg ) 16 \pi = \dfrac{dx}{dt}[/tex]

[tex]\dfrac{dx}{dt} = \dfrac{800 \pi}{7} \ miles/min[/tex]

Answer:

9

Step-by-step explanation:

Expected number of defective is given as :

N x P = np

Where = number of the sample drawn from the production lot

P= percentage of bulbs In The lot which are defective

N = 15

P = 60% = 0.60

So when we do the multiplication,

We have:

NP = 15x0.60

= 9

So in conclusion the expected value of defective bulbs in the sample is 9.

Answer:

78

Step-by-step explanation:

% profit= profit/CP ×100/1

Profit= selling price (S.P) - cost price(C.P)

%profit= 30

profit= 18

% profit= profit / CP×100/1

30= 18/CP ×100/1

30 = 1800 /CP

CP= 1800/30

CP =60

Recall that:

Profit= SP- CP

SP= Profit +CP

= 18+60

=78

Answer:

The value is  [tex]P(\= X \ge 515 ) = 0.8944[/tex]

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 500[/tex]

   The standard deviation is  [tex]\sigma = 60[/tex]

    The sample size is  n  =  25

Generally the standard error of mean is mathematically represented as

       [tex]\sigma _{\= x } = \frac{\sigma }{\sqrt{n} }[/tex]

=>    [tex]\sigma _{\= x } = \frac{60}{\sqrt{25} }[/tex]

=>    [tex]\sigma _{\= x } = 12[/tex]

Generally the  probability that a random sample of size 25 selected from the population will have a sample mean greater than or equal to 515 is  mathematically represented as

         [tex]P(\= X \ge 515 ) = 1 - P(\= X < 515)[/tex]

Here  [tex]P(\= X < 515) = P(\frac{\= x - \mu }{\sigma_{\= x }} < \frac{515 - 500}{12} )[/tex]

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

          [tex]P(\= X < 515) = P(Z < 1.25 )[/tex]

From the z table the probability of  (Z  <  1.25  )

    [tex]P(Z < 1.25 ) = 0.10565[/tex]

So

    [tex]P(\= X < 515) = 0.10565[/tex]

So

    [tex]P(\= X \ge 515 ) = 1 - 0.10565[/tex]

=>  [tex]P(\= X \ge 515 ) = 0.8944[/tex]
