Answer:
Step-by-step explanation:
Given equation is,
x² + (p + 1)x = 5 - 2p
x² + (p + 1)x - (5 - 2p) = 0
x² + (p + 1)x + (2p - 5) = 0
Properties for the roots of a quadratic equation,
1). Quadratic equation will have two real roots, discriminant will be greater than zero. [(b² - 4ac) > 0]
2). If the equation has exactly one root, discriminant will be zero [(b² - 4ac) = 0]
3). If equation has imaginary roots, discriminant will be less than zero [(b² - 4ac) < 0].
Discriminant of the given equation = [tex](p+1)^2-4(1)(2p-5)[/tex]
For real roots,
[tex](p+1)^2-4(1)(2p-5)>0[/tex]
p² + 2p + 1 - 8p + 20 > 0
p² - 6p + 21 > 0
For all real values of 'p', given equation will be greater than zero.

In a batch of eggs, 3% were broken. There were 18 broken eggs
How many eggs were there in the batch?
Answer: 600 eggs
Step-by-step explanation:
Let total number of eggs be x.So, 3% of x were broken and there were 18 broken eggs. We can write this as: 0.03*x =18x=18/0.03x= 600 eggs (answer).
Total number of eggs in the bags are 600.
What is Percentage?Percentage is a number or ratio that can be "expressed as a fraction of 100".
According to the question,
Percentage of broken eggs = 3%
Number of broken eggs = 3/100 = 0.03
To calculate the total number eggs,
[tex]\frac{3}{100}[/tex] (x) = 18
x = 1800/3
x = 600.
Hence, the total number of eggs in bags are 600.

Answer:
im pretty sure its 36%
Step-by-step explanation:
Caroline, Colin & Sarah share some money.
Caroline gets 1/9 of the money.
Colin and Sarah share the rest in the ratio 1:3.
What proportion does Sarah get?
Answer:
2 ÷ 3
Step-by-step explanation:
Let us suppose the money be 90
Since caroline gets 1 by 9 of the money i.e. 10
And, the remaining money would be distributed among Colin and sarah in the ratio of 1:3
So, the remaining money would be
= 90 - 10
= 80
So, the sarah could get
= 80 × 3 ÷ 4 ÷ 90
= 60 ÷ 90
= 20 ÷ 30
= 2 ÷ 3

7. Find the value of x 8. find the value of y
Answer:
x = 27.8
y = 35
Step-by-step explanation:
∡D ≅ ∡A, therefore:
65 = 2y - 5
70 = 2y
y = 35
EF ≅ BC, therefore:
2x + y = 90.6
2x + 35 = 90.6
2x = 55.6
x = 27.8

Step-by-step explanation:
Answer:
Step-by-step explanation:
Remark
This is a Pythagorean Problem
Formula
a^2 + b^2 = c^2
a = 5
b = ?
c = 9
Solution
5^2 + b^2 = 9^2 Expand the givens
25 + b^2 = 81 Subtract 25 from both sides
25-25+b^2 = 81- 25
b^2 = 56
√b^2 = √56
b = √8*7
b = √2*2*2*7
b = 2 √2*7
b = 2 √14

Answer: (6, -6)
Step-by-step explanation:
so midpoint =([tex]\frac{X1+X2}{2}[/tex],[tex]\frac{Y1+Y2}{2}[/tex])
for x co ordinate
[tex]\frac{-2+X2}{2}[/tex]=2
-2+X=4 (X2=x co ordinate point for b, can be written as just x now)
X=6
x co ordinate of B= 6
y co ordinates of y
[tex]\frac{-8+Y2}{2}[/tex]=-7
-8+Y=-14
Y=-6
co ordinates B (6,-6)
for proof/extra explanation (NOT necessary for working):
[tex]\frac{Y1+Y2}{2}[/tex]
=[tex]\frac{(-2)+6, (-8)+(-6)}{2}[/tex]
=[tex]\frac{4, -14}{2}[/tex]
=(2,-7)

Given that lines q and m are parallel and are cut by two
different transversal lines, j and k, use angle relationships
to determine the measure of each numbered angle:
angle 1 = 180-110 = 70 degrees (linnear pair)
angle 2= 180-115 = 65 degrees (linnear pair)
angle 3 = angle 2 = 65 degrees (corresponding angles)
angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)
(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)
angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees
angle 6 = angle 7 = 45 degrees ( vertical angles)
angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)
angle 9 =angle 6 = 45 degrees (corresponding angles)
angle 5=angle 9=45 degrees (vertical angles)

Which histograms are approximately symmetric and bell shaped?
Answer:
B and E
Step-by-step explanation:
im pretty sure what you have is correct
The correct histograms that are approximately symmetric and bell-shaped are - histograms B, C, and E because they are symmetric and bell-shaped.
A histogram is a convenient form or graphical representation of the frequency distribution of numerical data by means of rectangles. These histograms are found in different shapes and symmetries.
Bell-shaped curve:
if a histogram resembles or looks like a “bell” by joining the interval of rectangles in a curve and has one single peak in the middle of the distribution.In the given histograms only histogram shows a bell-like curve when joining the middle point of rectangles of distribution and also present in symmetry.in the image attach approximate curves are form you can see if it is bell shape and symmetric.Thus, the correct answer is - Histograms B, C, and E.
