What is an equation of the line that passes through the points (1,4) and (-2,-8)?

natita [175]

Answer: I know it 4 but I don’t know the equation for it, I can only help you this far.(hope it help)

Step-by-step explanation:

(1,4) and (-2,-8)

(x is the first number of the point which is 1 and -2, y is the second number of the point which is 4 and -8.)

(x1 is 1, it alway the first point they tell you on the problem like (1,-4) is on the problem first so it gonna be x1 and y1, for x2 it -2, it alway the second point in the problem like (-2,-8) is the second point they tell you so it gonna be y1 and y2.)

Do x2 - x1 and y2 - y1(y/x)

-8 - 4/-2 - 1 = -12/-3

-12/-3 divide top and bottom by -3, that would equal to 4

Delicious Candy markets a two-pound box of assorted chocolates. Because of imperfections in the candy making equipment, the actu

nikitadnepr [17]

Answer:

a. $f(x)= 1.25\ \ \ \ , \ for \ 31.8\leq x\leq 32.6$

$b. \ P(X=32)=0\\P(X>32.3)=0.375\\P(X$

c. No. Delicious Candy isn't violating any government regulations

Step-by-step explanation:

-A uniform distribution is given by the formula:

$f(x)=\frac{1}{b-a} \ \ \ for \ \ \ a\leq x\leq b$

#we substitute our values in the formula above to determine the distribution:

$f(x)=\frac{1}{b-a}\\\\=\frac{1}{32.6-31.8}\\\\=1.25\\\\\therefore f(x)=1.25, \ \ \ 31.8\leq x\leq 32.6$

Hence, the probability density function for the box's weight is given as: $f(x)=1.25, \ \ \ 31.8\leq x\leq 32.6$

b. The probability of the box's weight being exactly 32 ounces is obtained by integrating f(x) over a=b=32:

$f(x)=1.25, \ \ \ a\leq x\leq b\\\\=\int\limits^{32}_{32} {1.25} \, dx \\\\\\=[1.25x]\limits^{32}_{32}\\\\\\=1.25[32.0-32.0]\\\\\\=0$

Hence, the probability that a box weighs exactly 32 ounces is 0.000

ii.The probability that a box weighs more than 32.3 is obtained by integrating f(x) over the limits 32.3 to 32.6 :

$f(x)=1.25, \ \ \ a\leq x\leq b\\\\=\int\limits^{32.6}_{32.3} {1.25} \, dx \\\\\\=[1.25x]\limits^{32.6}_{32.3}\\\\\\=1.25[32.6-32.3]\\\\\\=0.375$

Hence, the probability that a box weighs more than 32.3 ounces is 0.3750

iii. The probability that a box weighs less than 31.8 is 0.000 since the weight limits are $31.8\leq x\leq 32.6$ .

-Any value above or below these limits have a probability of 0.000

c. Let 32 ounces be the government's stated weight.

$1.25(32.6-32)=0.75\\\\0.75>0.60$

Hence, Delicious Candy isn't violating any government's regulations.

What is the solution of the equation? 2(x+6)3−−−−−−−√5 + 3 = 19

joja [24]

Answer:

x = 10.58

Step-by-step explanation:

It seems the equation is following

$\frac{2(x+6)3}{\sqrt{5}+3}=19\\\\$

3 and 2 will simpy multiply and become 6

$\sqrt{5}+3$ will go to RHS and will multiply with 19

$6(x+6)= 19(\sqrt{5}+3)\\\\$

6(x+6) will become = 6x + 36

$6x+36 = 19\sqrt{5}+57)\\\\$

$6x = 19\sqrt{5}+57-36\\\\$

$19\sqrt{5} = 42.48$

6x = 42.48 + 21

6x = 63.48

x = 10.58
