Answer:

27

Step-by-step explanation:

We know the missing angle for the triangle on the left is 63. And that is the same angle reflected to the other side. There is a right angle so its 63 + 90 = 157.

180 - 157 = 27

Step-by-step explanation:

f(x)=7x^(2)-5

f(4) means that x=4

f(4)=7*4^(2)-5

    = 7 * 16 -5

    = 112 -5

    = 107

Answer: Someone who sells tickets is always in the ticket wagon, which is stationery in spite of its wheels.

Step-by-step explanation: Do usage of the comma in answers C , and D are incorrect , so that leaves us with answers A and B , in option A stationery is miss spelled so your answer would be : Someone who sells tickets is always in the ticket wagon, which is stationery in spite of its wheels.

Answer:

By the Central Limit Theorem, the sampling distribution is approximately normal, with mean 30 and standard deviation 0.1.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

The batteries produced in a manufacturing plant have a mean time to failure of 30 months with a standard deviation of 2 months.

This means that [tex]\mu = 30, \sigma = 2[/tex]

Sample of 400 batteries. The sampling distribution of is approximately:

So [tex]n = 400, s = \frac{\sigma}{\sqrt{n}} = \frac{2}{\sqrt{400}} = 0.1[/tex]

By the Central Limit Theorem, the sampling distribution is approximately normal, with mean 30 and standard deviation 0.1.

Answer:

= 0.3478  

Step-by-step explanation:

Given:-

- The number of sophomore, S = 150

- The sophomore and had summer internship, x = 80

- The number of juniors, J = 200

- The junior and had summer internship, y = 150

Find:-

What is the probability that the person is a sophomore given that the person had a summer internship?

Solution:-

- The total sum of sophomore and junior students is N:

                        N = S + J

                        N = 150 + 200

                        N = 350 students.

- We will denote event A as random selection of sophomore from total.

- We will denote event B as random selection of student who had summer internship.

- We are to determine the conditional probability that a person selected is sophomore given that the person had a summer internship. That is the probability of event A given that event B has already occured.

- The conditional probability can be written as:

                       P ( A / B ) = P ( A & B ) / P ( B )

Where,

       P ( A & B ) : The probability the person is a sophomore and had a summer internship.

       P ( B ): The probability that the person selected had a summer internship.

                     P ( A & B ) = x / N

                                       = 80 / 350

                                       = 0.22857143

                    P ( B ) = ( x + y ) / N

                              = ( 80 + 150 ) / 350 = 230/350

                              = 0.65714286

Therefore the required probability is:

                    P ( A / B ) = 0.22857143 / 0.65714286

                                     = 0.3478  ... Answer

Answer:

h=2 3/4

Step-by-step explanation:

2 3/4+1/2=

you can convert 1/2 into 2/4 so they have like denominators

2 3/4+2/4= 2 5/4 which is also equal to 3 1/4

Answer:

Volume of the cone is increasing at the rate [tex]9916\pi \frac{in^3}{s}[/tex].

Step-by-step explanation:

Given: The radius of a right circular cone is increasing at a rate of [tex]1.9[/tex] in/s while its height is decreasing at a rate of [tex]2.2[/tex] in/s.

To find: The rate at which volume of the cone changing when the radius is [tex]134[/tex] in. and the height is [tex]136[/tex] in.

Solution:

We have,

[tex]\frac{dr}{dt} =1.9 \:\text{in/s}[/tex], [tex]\frac{dh}{dt}=-2.2\:\text{in/s}[/tex], [tex]r=134 \:\text{in}[/tex], [tex]h=136\:\text{in}[/tex]

Now, let [tex]V[/tex] be the volume of the cone.

So, [tex]V=\frac{1}{3}\pi r^{2}h[/tex]

Differentiate with respect to [tex]t[/tex].

[tex]\frac{dv}{dt} =\frac{1}{3}\pi \left [ r^2\frac{dh}{dt}+h\left ( 2r \right )\frac{dr}{dt} \right ][/tex]

Now, on substituting the values, we get

[tex]\frac{dv}{dt} =\frac{1}{3}\pi\left [ \left ( 134 \right )^2\left ( -2.2 \right )+\left ( 136\right )\left ( 2 \right )\left ( 134 \right )\left ( 1.9 \right ) \right ][/tex]

[tex]\frac{dv}{dt} =\frac{1}{3}\pi\left [ -39503.2+69251.2 \right ][/tex]  

[tex]\frac{dv}{dt} =\frac{1}{3}\pi\left [ 29748 \right ][/tex]

[tex]\frac{dv}{dt} =9916\pi \frac{in^3}{s}[/tex]

Hence, the volume of the cone is increasing at the rate [tex]9916\pi \frac{in^3}{s}[/tex].

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

Neither linear nor exponential functions have a "wiggle" in their graph, so the piece in the region x < 0 is polynomial.

The piece in the interval [0, 3] is concave upward and has increasing slope. It could be polynomial, but is most likely the exponential piece of the function.

For x > 3, the function is linear.

There are no gaps in function value where the transition is made from one piece to another, so the function is continuous.

The function tends upward at the right side of the graph. It tends downward at the left side of the graph. This tells you the sign of the infinity they tend toward matches the sign of the infinity x tends toward.

__

On the interval [0, 3], h(x) is represented by an exponential function.

H(x) is a continuous function.

As x approaches +∞, h(x) approaches +∞.

As x approaches -∞, h(x) approaches -∞.

Answer:

Step-by-step explanation:

Inscribed angle → ∠VXY

(Angle included between two chords meeting at a point on circumference)

Minor arc → (arc VY)

(Arc measuring less than 180° is called as minor arc)

Semicircle → (arc VWX)

(Arc inscribed by the diameter)

m(arc VWX) = 180°

(Semicircle)

m(∠VUW) = 110°

(Central angle subtended by an arc)

Answer:

Step-by-step explanation:

The surface area of a rectangular prism is

A=2(xy+xz+yz), where x,y,z are the dimensions, in this case

A=2(8(8)+8(10)+8(10))

A=2(64+80+80)

A=2(224)

A=448in^2

So the minimum amount of wrapping paper is 448in^2

Answer:

a = 12

Step-by-step explanation:

as C^2 = A^2 + B^2

by Pythagoras theorem

so

A^2 = C^2 - B^2

= 13^2 - 5^2

= 169- 25

144

as 12^2 is equal to 144

hence side a is equal to 12

Answer:

[tex]h^2 = p^2 + b^2 \\ {13}^{2} = {p }^{2} + {5}^{2} \\ 169 = {p }^{2} + 25 \\ 169 - 25 = {p}^{2} \\ 144 = {p}^{2} \\ \sqrt{144} = p \\ 12 = p \\ p = 12[/tex]
