it would be something like this:

f(x) = 12 + x(4%)

but if you want it in y format then:

y = 12 + x(4%)

Answer:

50 questions.

Step-by-step explanation:

if you divide 100 by 49 you get 2.04 round down, each question is 2 points per question and the student got a 98% then just multiply 49 by 2 just to make sure, then go up. 50 times 2 is 100%, so the answer is 50 questions

Answer: 165 different combinations.

Step-by-step explanation:

Here we first need to identify the "selections", and then the number of options for each selection.

Here we have two selections, shorts, and sleeveless blouses.

For shorts, we have 15 options.

For sleeveless blouses, we have 11 options.

The total number of combinations will be equal to the product between the numbers of options for each selection, then the total number of combinations is:

C = 11*15 = 165

Answer:

3. (x-6)

Step-by-step explanation:

x^2-5x-6

--

Find factors of -6 that could be added that equals to -5

Factors=

-6 and 1

x^2-5x-6 factored is (x-6)(x+1)

so the answer would be (3) (x-6)

Answer: 25.52771

Step-by-step explanation:

i got this answer and it was right :D

The required answer would be 25.48271 if 25.48271 increased by 45 thousandths.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

We have been given that 25.48271 increased by 45 thousandths.

Therefore, 25.48271 + 45/1000

⇒ 25.48271 + 0.045

⇒ 25.52771

Hence, the required answer would be 25.48271.

Answer: Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds. Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds. Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris. Which of the following represents the shape of the sampling distribution for x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C?

Normal, because both population distributions are Normal.  

Uniform, because the both sample sizes are less than 30.

Skewed right, because the difference in times cannot be negative.

Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.

Step-by-step explanation: Can someone tell me the answer?

Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.

Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds.

Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds.

Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris.

The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.

Normal, because both population distributions are Normal.  

Uniform, because both sample sizes are less than 30.

Skewed right, because the difference in times cannot be negative.

Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.

Lets us start with finding the inner angles of the triangle. The bottom right angle shall be 70 degrees as it is opposite. The 100 degrees shall add together to make 200. 360-200 = 160. 160 / 2 = 80. So, Now we know bottom left angle (80) and bottom right (70). 80 + 70 = 150. In a triangle, angles add to 180 so 180 - 150 = 30. 30 = 2x which means that x = 15

Answer:

400

Step-by-step explanation:

u = 50 km/hr

v = 100 km/hr

d = 300 km

b = 200 km/hr

= b*d/(u+v)  

=  200* 300/(50+100)  

= 400

Answer:

[tex]m=\frac{2}{5}[/tex]

Step-by-step explanation:

1. To find the slope we need to use the slope formula, [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

2. The points that were given were (0,0) and (5,2). Let's plug those into the formula.

[tex]\frac{2-0}{5-0}[/tex]

[tex]\frac{2}{5}[/tex]

So, your slope would be [tex]m=\frac{2}{5}[/tex]

Answer:

4d−3

Step-by-step explanation:

5d−7−d+4

Combine 5d and −d to get 4d.

4d−7+4

Add −7 and 4 to get −3.

4d−3

The simplified expression is 4d - 3.

Given is an expression 5d - 7 - d + 4 we need to simplify it,

We know that,

An expression is a combination of numbers, variables, and operations that can be evaluated to produce a value.

It can represent a mathematical relationship or a computation.

To simplify the expression 5d - 7 - d + 4, we can combine like terms.

First, let's group the terms with the variable "d" together:

(5d - d) - 7 + 4

Simplifying within the parentheses:

4d - 7 + 4

Combining the constants:

4d - 3

Therefore, the simplified expression is 4d - 3.

Answer:

Step-by-step explanation:

so we can use [tex]t^{2}[/tex] + 25  as one expression and the find the distance between the points and set the expression equal to that number.  That's our strategy.

dist = the square root  of [tex]x^{2}[/tex]  + [tex]y^{2}[/tex]  

where x and y are the change in x2 to x1 and y2 to y1

P1 = ( -3, -5)

P2 = (2, 7 )

dist = square root of (  [2 -(-3) ]^2  + [7-(-5)]2)

dist = sq rt  ( 5^2 + 12^2 )

dist = sq rt ( 25 + 144)

dist = sq rt (169)

dist = 13

now set our eq.  equal to that number

[tex]t^{2}[/tex] + 25 = 13

[tex]t^{2}[/tex] = -12

Step-by-step explanation:

Answer:

Dont think eh multiplied both sides by 4. That would be the first step.

Step-by-step explanation:

1/4(x+12)=2

multiply both sides by 4

x+12=8

move the 8 to the right side of the equation and change its sign

x=8-12

calculate

x= -4

Answer:

He didn't multiply 1/4 between both terms in the brackets.

Step-by-step explanation:

1/4(x+12)=2

1/4x+3=2
