Answer:

$840

Step-by-step explanation:

Given data

Principal = $3000

Rate= 7%

Time= 4 years

The expression for the simple interest is

SI= PRT/100

substitute

SI= 3000*7*4/100

SI= 30*7*4

SI= $840

Hence the interest is $840

Answer: the median is 30 and the mean is 26.4

Step-by-step explanation: to find the median you order it from least to greater and find the middle number. For the mean add all numbers and divide from how many numbers are there , so you would divide by 5.

Step-by-step explanation:

Answer:

x= -4, y= -20

Step-by-step explanation:

y= 16x+44

(y= -x²+8x+28) * (-1)

multiply both sides by -1  

y= 16x+44

-y= x²-8x-28

add the equations to eliminate y

y-y= x²+16x-8x+44-28

0= x² +8x +16 this is the same with (x+4)²=0 so x= -4

go back to the first equation and substitute x with -4 and solve for y

y= 16*(-4) +44 = -64+44 = -20

Answer:

195 m

Step-by-step explanation:

first find the area of the whole square (15x15=225) then find the area of the rectangle inside (6x5=30) then subtract 30 from 225 which leaves you with 195

You have to find the area of the little square first, so that's 6 x 5 which is 30. Then find the area of the shaded part. 15 x 15 = 225. Then subtract both numbers. And you'll get "195 m" which is your answer.

Answer:

56

Step-by-step explanation:

Zoe and Hannah shared tips in the ratio

3:7

Last week Zoe received $24

Hence the amount received by Hannah can be calculated as follows

3/7= 24/x

168= 3x

x= 168/3

= 56

Hence Hannah received €56

Answer:

Y= 1.1x^2 + 4.2x - 4.9

Step-by-step explanation:

It told me I got it correct.

An equation is formed of two equal expressions. The equation that passes through each of the data sets is y= 1.1x² + 4.2x – 4.9. Hence, the correct option is B.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

To find the equation that best represents this data set, plot each of the data on the graph, and plot each of the equations as well.

The other way is to check if all the data point when substituted into the equation than it satisfies the equation or not.

Thus, the equation that passes through each of the data sets is y= 1.1x² + 4.2x – 4.9. Hence, the correct option is B.

Answer:

P(candy chosen is red) = 58/200

Step-by-step explanation:

0.29 is the probability that a candy chosen at random will be red.

The probability exists the branch of mathematics involving numerical descriptions of how likely an event exists to happen, or how likely it exists that a proposition stands true. The probability of an event exists in a number between 0 and 1, where, roughly speaking, 0 reveals the impossibility of the event, and 1 demonstrates certainty.

A machine contains = 76 green candies

B machine contains = 42 orange candies

C  machine contains = 58 red candies

D  machine contains = 24 yellow candies

Probability = 58 / 76 + 42+ 58+ 24

                  = 58 / 200

                  = 0.29

0.29 is the probability that a candy chosen at random will be red.

Answer:

[tex]y = 2x - 5[/tex]

Substitute the value of y as 2x - 5 in the equation.

[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]

Now, find the value of y

[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]

⎇ x = x = x, equals 10

⎇ y = y = y, equals 15

Answer:

if y = 2x-5

then in the second equation we can find the value of x

5x-4(2x-5) = -10

5x-8x+20 = -10

-3x = -30

x = 10

then the value of y = 20-5 = 15

therefore the value of x = 10 and y =15 (ans)

Answer: tanA=3/4

Step-by-step explanation: If  cosA=4/5 then

sinA=√(1−cos2A)  {Because sin^2A+cos^2A=1}

=>sinA=√(1−16/25)

=>sinA=√(9/25)

=>sinA=3/5

Now as  tanA=sinA/cosA

=>tanA=3/5×5/4  {Because 1/cosA=5/4}

=>tanA=3/4

Answer:

odd; even; even; odd

Step-by-step explanation:

The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We know when the graph is symmetric about the origin it is an off function.

When the graph is symmetric about the y axis it is an even function.

When f(-x) = f(x) it is an even function

When f(-x) = -f(x) it is an odd function.

Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

Answer:

Step-by-step explanation:

We can see that we need to plug in 2 for x in the first equation

We can also see that when x=2 we need to use the second part of the piecewise (because this one works when x is greater than or equal to 2)

so we have

3*(4*2+1)= 27

for g(x) we need to plug in x=1

we use the first piecewise equation because it's valid when x is less than 3

4(1²+2)=12

take their sum 27+12= 39
