Angles AXY and YXB are complementary angles because they add up to 90 degrees, which can be inferred by looking at angle BXC.

Answer:

d) 32.4%

Step-by-step explanation:

p(chance of winning general election) = (chance of winning primary)x(chance of winning general) = 60% x 54% = 0.6 x 0.54 = 0.324 = 32.4%

Answer: A

Step-by-step explanation:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.

The possible values of y are [-infinity,4], so the answer is A

Answer:

2000 ml of liquid

Step-by-step explanation:

1l plus 1l will equal 2l.

1 liter consists of 1000 milliliters ("milli" means thousand).

If 1l had 1000ml, 2l will have 2000ml.

So 2000mlnis the answer

Answer:

x=  −1 /2   or x=4

Step-by-step explanation:

This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step

2x^2−7x=4

Step 1: Subtract 4 from both sides.

2x^2−7x−4 =4 −4

2x^2−7x−4=0

Step 2: Factor left side of equation.

(2x+1)(x−4)=0

Step 3: Set factors equal to 0.

2x+1=0 or x−4=0

x=  −1 /2   or x=4

(BTW, there are supposed to be two answers, it's factoring)

Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)

Answer:

Probability that X <32 degrees

[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]

Convert this into percent by multiplying by 100

95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )​

Step-by-step explanation:

Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.

Let X be the minimum temperature in February

Then X is N(22,6)

To calculate  percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )

Probability that X <32 degrees

[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]

Convert this into percent by multiplying by 100

95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )​

(7.)  w >1.5

Step-by-step explanation:

Answer:

Exactly two distinct zeros

Step-by-step explanation:

y = 2(x-1) (x + 4)

Plug y = 0

0 = 2(x-1) (x + 4)

0/2 = (x-1) (x + 4)

(x-1) (x + 4) = 0

(x-1) = 0 or (x + 4)= 0

x = 1 or x = - 4

Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.

Answer:X=15d or just 15

Step-by-step explanation:Since there is an increase in manpower/hours of: [8 x 4] / [6 x 5] = 16/15, therefore, there must be decrease in days by the same pecentage. Or 16 / [16 / 15] =16 x 15/16 =15 days

Answer:

15 days

Step-by-step explanation:

Or you could just write 15 on MathsWatch

Answer:

B

Step-by-step explanation:

45-45-90 triangles have the ratio 1:1:sqrt(2) on their sides

20sqrt(2):20sqrt(2):20(2)/40 satisfies this ratio

you have two walls that are  10 by 7.5 so 75 feet ^2 in area each

you have another two walls that are 14 by 7.5  so 105 feet^ 2 each

so all of that together is 360 feet^2 to cover for one coating, so you have 720 feet^2 to cover for 2 coats on the walls. so take that and divide it by the area that one gallon would cover, then round up giving you how many gallons you would have to buy

for the ceiling you do the same, the area is 140 and you only need one coat

Step-by-step explanation:

Spinner divided to 5 equal parts

It is Numbered from (1 to 5): 1, 2, 3, 4, 5

Theoretical probability of spinning 1 = 1/5

Number of times it is spun = 50

Let Experimental probability of spinning 1 = x

1/5 = x/50

5x = 50

x = 50/5

x = 10

Experimental probability of spinning 1 = 10

Answer:

10

Answer:

The slope of the line is 5.

The point slope form of the line is y=5x+6.

Step-by-step explanation:

We can find the slope using this formula: [tex]\frac{y_{2} }{x_{2} } -\frac{y_{1} }{x_{1} }[/tex]

[tex]\frac{6}{0} -\frac{9}{-3} =[/tex]

[tex]\frac{6}{0} -(-\frac{9}{3} )=[/tex]

[tex]\frac{6}{0} +\frac{9}{3} =[/tex]

[tex]\frac{15}{3} =[/tex]

5

The slope of the line is 5.

To find point slope form, we use the equation y=mx+b where m is the slope and b is the y-intercept.

The y-intercept of this slope is 6 and the slope is 5 so we get, y=5x+6

Answer:

False

Step-by-step explanation:

A checkout clerk at a department store is expected to complete 16 transactions every hour

I.e 16 transactions in 60 minutes

So if it's 6 transactions, let's check to know if the minutes Tally.

16 = 60

6 = (6*60)16

6 = 22.5 minutes

But in the statement it was 20 minutes, so the answer is false.

Answer:

329.31

Step-by-step explanation:

The total percentage we have to add is

5+7+1+ .75 =13.75 %

Take the cost of the ticket and multiply by the percentage

289.50 * 13.75%

Change to decimal form

289.50* .1375

39.80625

Rounding to the nearest cent

39.81

Add this to the cost of the ticket

289.50+39.81

329.31

Step-by-step explanation:

a) 200,000 equals 2 times 10^5

b) 80,000 equals 8 times 10^4

c) 900,000,000 equals 9 times 10^8

d) 1,000,000,000 equals 1 times 10^9

Answer:

The graph is a nonlinear function. Michael Jordan's hang time is 0.9 seconds. The maximum height is about 1 meter. For t between t = 0.5 and t = 1, the height is decreasing.

Step-by-step explanation:

Okay the first one: It's nonlinear because its not a line, its a curve and its definitely not constant. The curve on the graph stops at (0.9,0) so his hangtime is 0.9 seconds. The peak of the curve is about 1 meter. Pretty self explanatory. And the last one, after the point 0.5, the height of the curve goes down, so it is decreasing.

Answer:

The graph is a nonlinear function

Michael Jordan's hang time is 0.9 seconds

The maximum height is about 1 meter

For t between t = 0.5 and t = 1, the height is decreasing.

Answer:

x = 7

Step-by-step explanation:

8x - 2y = 48

Let y=4

8x - 2(4) = 48

8x -8 = 48

Add 8 to each side

8x -8+8 = 48+8

8x = 56

8x/8 = 56/8

x = 7

Answer:

82 minutes.

Step-by-step explanation:

So first calculate the percentage 37 minutes is. It is 45%

Next find how much 1% is.

Divide by 45.

[tex]\frac{37}{45}[/tex]

Multiply by 100 to find how much the whole time is: [tex]\frac{3700}{45}[/tex]

The decimal version is: 82.2222222222...

Which simplifies to 82 minutes.

Answer:

82 mins

Step-by-step explanation:

percentage of pages she has already read

100-55= 45%

45%----------- 37mins

55%------------ x mins

x =( 37× 55)/45

x= 45.22 mins

approximately x=45 mins

The time for reading assignment is 37mins + 45 mins = 82 mins.

Answer:

X=0 or x=-5

Step-by-step explanation:

[tex] {x}^{2} + 5x = 0 \\ x(x + 5) = 0[/tex]

X=0 or x+5=0 => X=-5
