Please help me with this question please

Answer:

Hi, I think it's DEGF

Step-by-step explanation:

for y=x－2,

just move y=x down 2 units.

for x=－2,

it's the easiest one, just see if there is a vertical crossing －2 on the x-axis.

for－2x+4,

you can see it as move y=－2x up 4 units, and for y=－2x, you can find it out by sub (1,-2) and (0,0) onto the graph.

for x²-4,

see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.

Hope this will help u!!

Answer:

Step-by-step explanation:

answer should be 0.39

The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is 0.39.

Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?

Given:

A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line.

Assuming that field goal attempts can be considered random events.

P = 0.85

n = 5

Standard deviation = √{5 x 0.85 x (1 - 0.85) = 0.79

The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is,

= P (X ≥ 4)

= P (X ≥ 3.5)

= 1 - P(X < 3.5)

= 0.39

Therefore, the probability is 0.39.

Answer:

1.19

Step-by-step explanation:

The original full amount is 100%.

When you increase the full amount by 19%, you add 19% of the full amount to the full amount, so now you have 119%.

To find 119% of an amount, multiply he amount by 1.19 since 119% = 1.19

Answer: 1.19

Answer:

48.76%

Step-by-step explanation:

Here is the complete question;

A brand of cereal had 1.21milligrams of iron per serving. Then they changed their recipe so they had 1.8mg of iron per serving. What was the percent increase in iron?

Given

Initial amount of iron in cereal per serving = 1.21mg

final  amount of iron in cereal per serving =1.8mg

Required

Percentage increase in iron

Increment = 1.8mg - 1.21mg

Increment = 0.59mg

% increase in iron = increment/original amount * 100%

% increase in iron = 0.59/1.21 * 100

% increase in iron = 0.4876 * 100

% increase in iron = 48.76%

Hence the percent increase in iron is 48.76%

Answer:

48%

Step-by-step explanation:

Given that,

No of 316 customers the first weekend it opened.

The second weekend it had 468.

We need to find the percent of increase in the number of customers.

The formula of percentage is given by :

[tex]\%=\dfrac{|\text{old number-new number}|}{\text{old number}}\times 100[/tex]

Here, old number = 316 and new number = 468

So,

[tex]\%=\dfrac{|316-468|}{316}\times 100\\\\\%=48.10\%[/tex]

or

% = 48%

So, the percent of increase in the no of customers is 48.

Answer:

18

Step-by-step explanation:

[tex]\frac{1}{5}[/tex] × 60 = 12 ← number who chose basketball

[tex]\frac{1}{2}[/tex] × 60 = 30 ← number who chose volleyball

That is a total of 12 + 30 = 42 students

Since the remaining students chose soccer, then

60 - 42 = 18 ← number who chose soccer

Answer:

[tex]a^{3}[/tex] * [tex]b^{2}[/tex]

Step-by-step explanation:

[tex]\frac{a^{12} * b^{7} }{a^{9} * b^{5} }[/tex]

Divide the equation (split the equation into parts), to show like terms;

[tex]\frac{a^{12} }{a^{9} }[/tex] * [tex]\frac{b^{7} }{b^{5} }[/tex]

Since dividing two numbers with exponents,( that have the same base), is equivalent to subtracting the exponents and retaining the base, hence:

[tex]a^{3}[/tex] * [tex]b^{2}[/tex]

Answer:X = 48

Step-by-step explanation:

Solve for  

x

by simplifying both sides of the equation, then isolating the variable.

The value of x in the equation given 3x/4 - 9 = 27, is 48.

Given is an equation, 3x/4 - 9 = 27, we need to find the value of x,

To find the value of x, we can solve the given equation step by step. Let's go through the process:

Start with the equation:

3x/4 - 9 = 27

To eliminate the fraction, we can multiply both sides of the equation by 4:

4 × (3x/4 - 9) = 4 × 27

Simplifying, we have:

3x - 36 = 108

Add 36 to both sides of the equation to isolate the variable:

3x - 36 + 36 = 108 + 36

Simplifying further:

3x = 144

Divide both sides of the equation by 3 to solve for x:

(3x) / 3 = 144 / 3

This gives us:

x = 48

Therefore, x equals 48 in the given equation: 3x/4 - 9 = 27.

Answer:

[tex]\boxed {m = 1}[/tex]

Step-by-step explanation:

Use the Slope Formula to determine the slope of two given points:

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

First Point: [tex](x_{1}, y_{1})[/tex]

Second Point: [tex](x_{2}, y_{2})[/tex]

-Substitute both points:

First Point: [tex](3, -4)[/tex]

Second Point: [tex](1, 2)[/tex]

[tex]m = \frac{2 + 4}{1 - 3}[/tex]

-Solve for the slope:

[tex]m = \frac{2 + 4}{1 - 3}[/tex]

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

[tex]\boxed {m = 1}[/tex]

Therefore, the slope is [tex]1[/tex].

Answer:

The answer is p=33.

Step-by-step explanation:

First you need to add 7.2 to the both sides in order to get rid of 7.2. On the left hand side, you'll have 11.0, directly 11. Since, [tex]\frac{p}{3} =11[/tex] multiply the both sides with 3, and you'll get p=33.
