is 0.02 greater than 0.1
Answer:
No.
Step-by-step explanation:
Since there is a 1 in the tenths place for 0.1, and nothing in the tenths place for 0.02, 0.1 is greater.
The decimal number 0.1 is greater than 0.02. Therefore, the given statement is false.
The given decimal numbers are 0.02 and 0.1.
Similar to comparing other whole numbers, while comparing decimals, one should start with the digits with the highest place value. We first create a place value table with the supplied decimal numbers before starting the comparison. If the digits on the biggest place value match, we go to the digits in the next place to the right. We keep comparing digits until we reach the ones that are different.
Here, 0.1 is greater than 0.02.
Therefore, the given statement is false.

Answer:
No real number solutions.
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
The discriminant is b² - 4ac
• If b² - 4ac > 0 the equation has 2 real and distinct roots
• If b² - 4ac = 0 the equation has 2 real and equal roots
• If b² - 4ac < 0 the equation has no real roots
Given
2x² + 4x + 8 = 0 ← in standard form
with a = 2, b = 4 and c = 8, then
b² - 4ac = 4² - (4 × 2 × 8) = 16 - 64 = - 48 , thus
The equation has no real number solutions because the discriminant is < 0

A set of physics exam scores are normally distributed with a mean of 80 points and a standard deviation of 6
points. Irina got a score of 95 points on the exam.
What proportion of exam scores are lower than Irina's score?
You may round your answer to four decimal places.
Answer:
The proportion of exam scores that are lower than Irina's score is 0.9938
Step-by-step explanation:
Data
mean: 80 pointsstandard deviation (sd): 6 pointsvalue of interest (x): 95 pointsz-score is computed as follows:
z = (x - mean)/sd
z = (95 - 80)/6 = 2.5
We want to find:
P(z < 2.5)
From the table attached:
P(z < 2.5) = 0.9938

Angle BCD is a circumscribed angle of circle A. Angle BAC measures 53°.
What is the measure of angle BCD?
37°
53°
74°
106°
The measure of angle BCD in circle A is 74°.
What is a circle?A circle is the locus of a point such that its distance from a fixed point is constant.
From the circle:
BC = CD (tangents that meet at the same point are equal)
But ∠ABC = 90° (angle between tangent and radius)
In triangle ABC:
∠ABC + ∠BCA + ∠BAC = 180 (triangle)
90 + ∠BCA + 53 = 180
∠BCA = 37°
Hence:
∠BCA = ∠ACD = 37°
angle BCD = ∠BCA + ∠ACD = 37 + 37 = 74°
The measure of angle BCD in circle A is 74°.

kelly is hanging shelves in her closet. She can buy sheleves for $1.25 a foot. Kelly buys one 5-foot shelf and a shelf that measure 24 inches. The rest of her materials cost $90. How much change will she get it she pay with $100? please explain and show your work
The 24 inch shelve is 2 feet ( 1 foot = 12 inches)
She bout 7 feet of shelves (5 + 2 = 7)
The total cost for the shelves was 7 x 1.25 = $8.75
She spend an additional 90 so her total spent was 90 + 8.75 = $98.75
Now subtract her total from 100 to find the amount of change:
100 - 98.75 = 1.25
The change was $1.25

true?
The events are independent because P(blue). P(green) = P(blue and green).
The events are independent because P(blue). P(green) + P(blue and green).
The events are dependent because P(blue). P(green) = P(blue and green).
The events are dependent because P(blue). P(green) + P(blue and green).
Answer:
Not 100 percent sure but i think the correct answer is the last one.
Step-by-step explanation:
I know that the answer is either the last one or before the last because they are dependent on each other. This is because the probability of both increases when they are added together. The more you have the more likely to get one of them. I went for the last one because i think that the value of together is greater than when they are added.
Again, not 100 percent sure, tried to give it my best shot.

The width of a poster is 8cm less than the length. The perimeter is more than 184
cm. If the length and width are both integers, what is the minimum dimension for
the length?
Answer:
Denote the length is a, then the width is a - 8.
The perimeter is more than 184:
=> 2 x ( a + a - 8) > 184
=> 2a - 8 > 92
=> 2a > 100
=> a > 50
=> a = 51
=> Minimum dimension for the length: a = 51

5(y+2/5)= -13 (please have an explanation)
Answer:y=-3
Step-by-step explanation:5(y+2/5)=-13
so first you simplify both sides of the equation
(5)(y)+(5)(2/5)=-13
then you distribute
5y+2=-13
then you subtract 2 from both sides
5y+2-2=-13-2
5y=-15
then u divide both side by 5
5y=-15

A scale drawing is made to enlarge a picture by using a scale factor of 3. The enlarged picture is 9 inches by 15 inches. What are the dimensions of the original picture? 3 inches by 5 inches 3 inches by 15 inches 6 inches by 12 inches 27 inches by 45 inches
Answer:
3 inches by 5 inches.
Step-by-step explanation:
The scale factor is 3 so the original lengths are 1/3 of the enlarged , so the answer is 9/3 by 15/3
= 3 by 5.
The dimensions of the original picture is 3in by 5in
Scale factors and dimensionLet the original dimension of the drawing be x in by y in
If the dimension of the enlarged picture is 9 inches by 15 inches after using a scale factor of 3, then;
x = 9/3 = 3in
y = 15/3 = 5in
Hence the dimensions of the original picture is 3in by 5in
