Answer:

a = -30

Step-by-step explanation:

In order to solve for a in the equation [tex]\sf 11 = \dfrac{-3}{10} a + 2[/tex], we can follow these steps:

Subtract 2 from both sides of the equation:

[tex]\sf 11 -2= \dfrac{-3}{10} a + 2-2[/tex]

[tex]\sf 9 = \dfrac{-3}{10} a[/tex]

Multiply both sides of the equation by [tex]\sf -\dfrac{10}{3}[/tex]:

[tex]\sf 9 *-\dfrac{10}{3}= \dfrac{-3}{10} a*-\dfrac{10}{3}[/tex]

-30 = a

Therefore, the solution to the equation 11 a + 2[tex]\sf \dfrac{-3}{10} a + 2[/tex] is a = -30.

The equations that are equivalent are B×10p = 2 and D×p = 20.

Given, For $5.00, Jamie purchased a notebook and a box of pencils.

10 pencils are contained in a box, and the notepad costs $3.00.

The price of one pencil can be calculated using the equation 3+10p=5.

According to the question:

3 ₊ 10p = 5

10p = 5 ₋ 3

10p = 2

p = 2/10

p = 0.2

equations can be :

B × 10p = 2 and D × p = 0.20

Hence we get the equations as: B × 10p = 2 and D × p = 0.20

The correct answer is other measures of location need not be the same.

What is mean, mode, median and standard deviation?

When the group of numbers have the same mean then the other measures of location need not be the same. That means the standard deviation, median and mode should not be equal. All three widely used parameters that are mean, mode, median and standard deviation are the measure of central tendency.

If the given data has no outlier then mean value and the median value are closer to each other but the mode value is different. Similarly, standard deviation is calculated for the dispersion data. And it means when mean value is same then standard deviation will be different for a group of numbers.

Hope this helps! <3

Answer: 24

Step-by-step explanation:

t=seconds. h=height

t=3

h=3+55t-16t^2

h=3+55(3)-16(3)^2

h=3+165-16*9

h=168-144

h=24 ft

The ball's height 3 seconds after it was kicked is 24 feet above the ground.

Given that a formula h = 3 + 55t-16t² describes a ball's height above the ground h, which has been kicked vertically upward from a height of 3 feet with an initial speed of 55 feet per second.

We need to find the height of the ball after 3 seconds.

To find the ball's height 3 seconds after it was kicked, we can use the formula provided:

h = 3 + 55t - 16t²

where h represents the height in feet and t represents the time in seconds.

To find the height after 3 seconds (t = 3), plug the value into the formula and calculate:

h = 3 + 55(3) - 16(3)²

Now, perform the calculations step by step:

h = 3 + 55(3) - 16(9)

h = 3 + 165 - 144

h = 24 feet

Hence the required height is 24 feet.

The probability that four or fewer of the people who called will sign up for a class = 0.9805

For given question,

Eric estimates that one out of every five people who call for information about a class will sign up for the class.

Last week he receive nine calls.

We need to find the probability that four or fewer of the people who called will sign up for a class.

Total number of calls = 9

⇒ n = 9

Since one out of every five people who call for information about a class will sign up for the class.

the probability of success (p) = 1/5

                                                  = 0.2

and the probability of failure (q) = 1 - p

                                                      = 1 - 0.2

                                                      = 0.8

To find the probability that four or fewer of the people who called will sign up for a class.

So, x would take values 0, 1, 2, 3, 4

Using Binomial principal,

For x = 0,

[tex]P(x=0)= ~^9C_0(0.2)^0(0.8)^{9-0}\\\\P(x=0)=0.13422[/tex]

For x = 1,

[tex]P(x=1)= ~^9C_1(0.2)^1(0.8)^{9-1}\\\\P(x=1)=0.30199[/tex]

For x = 2,

[tex]P(x=2)= ~^9C_2(0.2)^2(0.8)^{9-2}\\\\P(x=2)=0.30199[/tex]

For x = 3,

[tex]P(x=3)= ~^9C_3(0.2)^3(0.8)^{9-3}\\\\P(x=3)=0.17616[/tex]

For x = 4,

[tex]P(x=4)= ~^9C_4(0.2)^4(0.8)^{9-4}\\\\P(x=4)=0.06606[/tex]

So, the required probability would be,

P = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4)

P = 0.1342 + 0.3020 + 0.3020 + 0.1762 + 0.0661

P = 0.9805

Therefore, the probability that four or fewer of the people who called will sign up for a class = 0.9805

The statement which must also be true is that: since line a is perpendicular to line P, any plane containing line a is perpendicular to line P.

A line can be defined as a mark with length and direction, that is created by a point that is moving across a surface. Also, a line can vary in length, width, direction, curvature, and color.

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

A conditional statement can be defined as a type of statement that can be written to have both a hypothesis and conclusion. This ultimately implies that, a conditional statement typically has the form "if P then Q."

Based on the number of students invited to the office and the number of Volleyball students who left, the number of students who were both prefects and volleyball players are 3 students.

Those who are only prefects are 4 students.

To find the number of students who were both prefects and volleyball players, the formula is

= Number of volleyball players who left + Total number of volleyball players - Number of students called to office

= 7 + 10 - 14

= 3 students

Number of students who were just prefects:
= Number of students called - Number of students who left - Number of students who are prefects and volleyball players

The original price of the table set was $400.

Customers are given discounts by shop owners in order to increase sales. A discount is a rebate or offer created to consumers on the listed price of goods.

Now, as per the given question;

The paid price by Maria is $240 called selling price.

The total discount on the table set was 40%.

Let us consider the original price/marked price of the table set was 'x'.

Then the formula for calculating the original price/market price is;

Marked price - discount = selling price

x - 40%of x = 240

x - (40x)/100 = 240

100x - 40x = 24,000

60x = 24,000

x = 400

Therefore, the original price of the table set was $400.

Angular velocity of pendulum is 3.216 rad/s.

In physics, the rotational velocity ( or ), also referred to as the angular frequency vector, is a pseudovector representation of how quickly an object's angular position or orientation varies over time (i.e. how quickly an object rotates or revolves relative to a point or axis). The pseudovector's direction is normal to the instantaneous plane of rotation or angular displacement, and its magnitude equals the rate at which the object is rotating or revolving. Traditionally, the right-hand rule is used to specify the direction of angular motion.

Orbital and spin angular velocities are the two forms of angular velocities.

For a small angle angular velocity of the pendulum is calculated as:

ω[tex]= \sqrt{\frac{g}{l} }[/tex]

Here, g= gravity acceleration and l = pendulum's length.

Conversation of unit of length are,

l=94.7 cm = 94.7 cm * ([tex]\frac{10^{-2}m}{1cm}[/tex]) = 0.947 m

Substitute l = 0.947 m and g = 9.80 [tex]m/s^2[/tex] in the expression ω[tex]= \sqrt{\frac{g}{l} }[/tex]

ω[tex]= \sqrt{\frac{9.80m/s^2}{0.947m} } = 3.216[/tex]
