Write an inequality and show on a number line all numbers: from (–3) to 2 exclusives.
Answer:
The inequality is -3 < x < 2
The number line is included
Step-by-step explanation:
To express the numbers as an inequality, we have for exclusive numbers the form, [-3, 2] which gives;
-3 < x < 2
We note that an exclusive number (or larger than and lesser than inequality) is represented by an empty in the numbers excluded (for strict equality)
Therefore, we draw a number line with empty circles at number points -3, and 2 as follows;
-4 -3 -2 -1 0 2 1 2 3 4 5

PUZZLE: READ THE CLUE BELOW: CLUE 1-THE THOUSANDS DIGIT IS 8 ,WHICH IS TWO MORE THAN THE HUNDREDS DIGIT. CLUE 2- THE UNIT DIGIT IS ONE LESS THAN THE TENS DIGIT. CLUE 3-THE HUNDREDS DIGIT IS DOUBLE THE UNITS DIGIT. WHAT IS THE NUMBER?
Answer:
8,643
Step-by-step explanation:
The thousands digit is 8 so we know it is 8,000 The hundreds digit is 2 less than 8, so it's 6, giving us 8,600. The units digit is half the hundreds digit, so it is half of 6, or 3, now we have 8,603. Lastly, the tens digit is one greater than the units digit, so it is 4, leaving you with 8,643.
A line contains the points (6,8), (-2, k) and (-10, 4). What is the value of k?

Answer:
a) x+3=19
Step-by-step explanation:
a)
x is the age of Ronald , Collin is three years older than Ronald , so if we add up x(Ronald's age) and 3(the difference between both of their ages), we would get Collin's age(19) . That is the explanation for this equation.
b)
x+3=19
x=19-3
x=16
thus , x is 16 , in other words , Ronald's age is 16.
The test statistic of z equals = 2.94 2.94 is obtained when testing the claim that p not equals ≠ 0.877 0.877. A. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. B. Find the P-value. C. Using a significance level of alpha α equals = 0.01 0.01, should we reject Upper H 0 H0 or should we fail to reject Upper H 0 H0?
Answer:
Step-by-step explanation:
The claim being tested is that p not equals ≠ 0.877
A) This is the alternative hypothesis and it is a two tailed test. It means that it can be in either direction.
B)Given that z = 2.94, the p value would be determined from the normal distribution table. Since the curve is symmetrical and it is a two tailed test, the p for the left tail and the right tail would be considered. We will look at the area in both tails. Since it is showing in one tail only, we would double the area
From the normal distribution table, the area above the test z score in the right tail is 1 - 0.998 = 0.002
We would double this area to include the area in the left tail of z = - 2.94 Thus
p = 0.002 × 2 = 0.004
C) Since alpha, 0.01 > than the p value, 0.004, then we would reject the null hypothesis, H0

(78) The flag of country Perralia has to contain three differently-colored stripes of the same width, all of which must be positioned either vertically or horizontally. If the flag of Perralia must consist of the national colors, which include green, red, yellow, black, and blue, how many different flags can be created
Answer:
120 flags
Step-by-step explanation:
Given that:
The flag of country Perralia has to contain three differently-colored stripes of the same width, r = 3 stripes
all of which must be positioned either vertically or horizontally = 2
If the flag of Perralia must consist of the national colors, which include green, red, yellow, black, and blue. So the number of color n = 5 colors
The objective is to determine how many different flags can be created.
Let us recall that;the arrangement of objects taking into account the different orders or arrangement is called permutation.
The same is applicable in this scenario as well.
The number of flags that can be created can be determined by considering the permutation of :
[tex]P_r = \dfrac{n!}{(n-r)!}[/tex]
[tex]P_r = \dfrac{5!}{(5-3)!}[/tex]
[tex]P_r = \dfrac{5!}{(2)!}[/tex]
[tex]P_r = \dfrac{5 \times 4 \times 3 \times 2!}{(2)!}[/tex]
[tex]P_r = {5 \times 4 \times 3[/tex]
[tex]P_r = 60[/tex]
However, Since all of the must be positioned either vertically or horizontally = 2
Then the total number pf flags that be created = 2 × 60 = 120 flags
Abigal found that she can drive 140 miles in 3 hours, including rest stops, on intersate highway. How long would it take her to drive the interstates from cleveland, ohio, to washington dc which is 350 miles?
Answer:
7.5 hours
Step-by-step explanation:
distance = rate * time (d=rt)
First we find her average rate, or speed:
140 miles = 3 hours * rr = [tex]\frac{140 miles}{3 hours}[/tex] = 46.6666 miles/hourNow we take that rate and use our second distance to find the time:
d = rt
t = d/r = 350 miles / 46.6666 miles/hour = 7.5 hours
Find the perimeter for a square if one side measures: 4.5 cm

Find the measure of angle FED and DEN. Thx!!!! :)
Answer:
m<FED=60, m<DEN=120
Step-by-step explanation:
m<FED=60
This is because <GEN and <FED are vertical angles.
Vertical angles are always congruent.
Vertical angles are formed by a pair of intersecting lines, and are the angles directly across from one another.
m<DEN=120
This is because <DEN and <GEN are supplementary.
Supplementary angles add up to 180 degrees.
We know this because a straight line is always 180 degrees.
So:
m<DEN+m<GEN=180
m<DEN+60=180
m<DEN=120

1/4 of a pipe is white , 1/2part of the remaining is blue. If the remaining part is black and the length of this blackpart is 5 1/4cm, find the length of the pipe.
Answer: 14 cm
Step-by-step explanation:
let's total length = h
white = 1/4h
remain = h - 1/4h
=3/4h
blue = 1/2 of remaining
=1/2 of 3/4h
=3/8h
remain part black = 3/4h - 3/8h
=3/8h
according to the question
3/8h = 5 1/4 cm
h = 14 cm
length of the pipe is 14 cm
Answer:
14The length of the pipe is 14.
Solution,
Let the total length be X cm
[tex]x - \frac{x}{4} -{ (x - \frac{x}{4} ) \times \frac{1}{2}} = 5 \frac{1}{4} \\ x - \frac{x}{4} - \frac{x}{2} + \frac{x}{8} = \frac{21}{4} \\ \frac{8x - 2x - 4x + x}{8} = \frac{21}{4} \\ \frac{3x}{8} = \frac{21}{4} \\ 3x \times 4 = 21 \times 8 \\ 12x = 168 \\ x = \frac{168}{12} \\ x = 14[/tex]

Therefore, Carlos graphed the perpendicular bisector of AB.
Find the volume of the composite figure below
Answer:
1386 in³
Step-by-step explanation:
Volume of the composite cone = volume of a hemisphere + volume of a cone
=>Find the volume of cone
Volume of cone = ⅓πr²h
π = 3.142
r = 7 in
h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]
h = √(225 - 49)
h = √176 ≈ 13 in
Volume of cone = ⅓*3.142*7²*13
= ⅓*2001.454 ≈ 667 in³
=>Find volume of hemisphere.
Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³
π = 3.142
r = 7 in
Volume = ⅔*3.142*7³ ≈ 719 in³
Volume of composite figure = 667+719 = 1386 in³
