40% of the employees at a large corporation are female. A sample of 50 employees is taken and gender is recorded. What is the probability of a sample proportion of females in the sample between
.35 and .45?
a) 0.0693 b) 0.2649
c) 0.5284 d) 0.72
Kindly explain it too with solution
will give you brainliest for correct answer
Answer:
c) 0.5284
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by the formula:
[tex]z=\frac{p_s-p}{\sigma_p} \\\\where\ p_s=sample\ proportion,p=population\ proportion,\\\sigma_p=standard \ error=\sqrt{ \frac{p(1-p)}{n}},n=sample\ size\\\\ z=\frac{p_s-p}{\sqrt{ \frac{p(1-p)}{n}}} \\\\Given \ that\ n=50,p=40\%=0.4\\\\For\ p_s=0.35:\\\\z=\frac{0.35-0.4}{\sqrt{\frac{0.4(1-0.4)}{50} } } =-0.72\\\\For\ p_s=0.45:\\\\z=\frac{0.45-0.4}{\sqrt{\frac{0.4(1-0.4)}{50} } } =0.72[/tex]
Hence from the normal distribution table, P(0.35 < x < 0.45) = P(-0.72 < z < 0.72) = P(z < 0.72) - P(z < -0.72) = 0.7642 - 0.2358 = 0.5284
Ana and Chuyen are exploringunderwater sea life while on a helmet divingadventure. Ana's location ismath−30feet below sealevel, and Chuyen's location ismath−12feet belowsea level. Which girl is located farther from sealevel?
Answer:
Ana
Step-by-step explanation:
Given that:
Ana's location = −30feet below sealevel
Chuyen's location = − 12feet below sea level
Sea level = point 0 ;
-30 feets below sea level
A depth of - 30, below the water surface.
A depth of - 12 below sea level ; a depth of 12 feets below the water surface
-30 feets is farther below the water surface than - 12 feets
Hence, Ana is farther below the sea level than Chuyen

If RSTU is translated by the rule (x,y) > (x+2, y-10) , in which quadrant will the image R'S'T'U be located ?
Answer:
D) Quadrant 3
Step-by-step explanation:
ok so lets get a random point and try it out i see -10 is a big number so i will use R and see where it is and then t
R(-8,3) so add 2 to x and minus 10 y
R'(-6,-7)
Now t
T(-4,9)
(+2,-10)
T'(2,-1)
It is Quadrant 3
If RSTU is translated by the rule (x, y) ⇒ (x + 2, y - 10) the image R'S'T'U be located at the D. Third quadrant.
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
From the given diagram, the coordinate of the vertex(T) is (- 4, 10).
Let, T' be the vertex when the quadrilateral is translated by the rule
(x, y) ⇒ (x + 2, y - 10).
Therefore, The translated coordinate of the vertex(T') is,
(- 4 + 2, 10 - 10).
= (- 2, 0).
So, The quadrilateral will lie in the third quadrant.

A camper leaves camp and travels 4 miles west and 3 miles north. How far is the camper from his original starting point?
Answer:
5 miles
Step-by-step explanation:
To answer this question, use the following:
According to pythagorean theorem, the hypotenuse of the triangle, c, with legs a and b, can be found with the following equation:
[tex]a^2+b^2=c^2[/tex]
Thus plugging in 3 for a and 4 for b:

Step-by-step explanation:
If white light is made up of all colors, how can you tell what color an object is.
Answer:
See explanation
Step-by-step explanation:
White light is composed of seven different wavelengths. This can easily be established by using a prism to separate the various wavelengths that constitute white light.
How come we get to tell if an object has a particular colour? We get to know colours because the observed colour of an object is the wavelength that is reflected by that object.
An object that absorbs all other wavelengths in the spectrum of white light but reflects red light will appear red to the eye.
please help! which sentence explains why the moon can be seen from the earth at night?
here are the options to choose from
Answer:
a
Step-by-step explanation:
Answer:
A - The Moon reflects light from the Sun.
Step-by-step explanation:
As the moon moves around the sun in a one month cycle, different parts of it are exposed to the sun. When it is exposed to the light from the Sun it is reflected and people on Earth could see it at night, and sometimes during the day as well.
Is the relation a function?
Answer:
yes
Step-by-step explanation:
For a relation to be a function each value of x in the domain must map to exactly one unique value of y in the range.
Since the relation is a straight line , then each value of x will only map to one unique value of y ( passes the vertical line test )

I(t) = 27, 992 * (1.017) ^ t covert to log
Answer:
By 2034 Texas per capita income would reach at least $50,000
Step-by-step explanation:
Given;
[tex]I(t) = 27,992(1.017)^t[/tex]
Converting the given function to log;
[tex]I(t) = 27,992(1.017)^t \\\\\frac{I(t)}{27,992} = (1.017)^t\\\\Log_{1.017} ( \frac{I(t)}{27,992} )= t \\\\(Based \ on \ log \ rule; if \ a = b^y , in \ log \ it \ will \ be \ written \ as, Log_b \ a = y)[/tex]
(B) When I(t) = $50,000, the time "t" will become;
[tex]Log_{1.017} ( \frac{I(t)}{27,992} )= t\\\\Log_{1.017} ( \frac{50,000}{27,992} ) = t\\\\Log_{1.017} (1.7862) = t\\\\34.4 \ years = t[/tex]
Thus, by 2034 Texas per capita income would reach at least $50,000

In the system of equations, b is a constant. If the system has infinitely many solutions, what is the value of b?
Answer:
The value of b is 9.5
Step-by-step explanation:
If a system of equations has infinitely many solutions, that means the two equations are equal
If the system of equations ax + by = c, dx + ey = f, then
a = d ⇒ coefficients of xb = e ⇒ coefficients of yc = f ⇒ numerical termsLet us use this fact to solve the question
∵ 3x - y = 19 ⇒ (1)
∵ 1.5x - 0.5 y = b ⇒ (2)
∵ This system of equations has infinitely many solutions
∴ The coefficients of x must be equal
∴ The coefficients of y must be equal
∴ The numerical terms must be equal
→ Multiply equation (2) by 2 to make the coefficients of x and y on it
equal the coefficients of x and y in equation (1)
∵ 2(1.5x) - 2(0.5y) = 2(b)
∴ 3x - y = 2b ⇒ (3)
→ By comparing equations (1) and (3), 19 must equal 2b
∵ 2b = 19
→ Divide both sides by 2
∴ b = 9.5
∴ The value of b is 9.5
Jack’s car used 18 gallons of gasoline to go 468 miles. At that rate, how many gallons would be used to go 754 miles? Explain how you know.
Answer:
29 gallons.
Step-by-step explanation:
For every gallon, a total number of 468/18 miles = 26 miles could be travelled.
And hence, to travel 754 miles, a total of 754/26 gallons = 29 gallons would be needed.

Solve for x and all the missing angles.
(-11+3y)
(34+Y)
(37+y)°
Answer:
y=24; Angle 1: 61 degrees; Angle 2: 58 degrees; Angle 3: 61 degrees
Step-by-step explanation:
-11+3y+34+y+37+y=180 The sum of all the angles in a triangle is 180 degrees.
60+5y=180 Combine like terms
5y=120 Subtract 60 from 180
y=24 Divide 120/5
Angle 1: -11+ 3(24)= 61 degrees
Angle 2: 34+24=58 degrees
Angle 3: 37 + 24= 61 degrees
