380 devided by 10 gives you 10 percent so it is 38 then half it for 5 percent wich is 19 then you just add 19 to 380 wich is 399

399 because 380 x .05 =19 and 19+380
=399

Plot the intercepts to graph the equation. x+y=3
andrey2020 [161]

Answer:  You will have points plotted at +3 on the y axis, and +3 on the x axis.

The attachment shows what your graph should look like.

Step-by-step explanation:

The intercept is where the graphed line crosses an axis.

To find the y-intercept, substitute 0 for x and solve for y:

0 + y = 3.  Subtracting 0, you have y = 3

So you can plot a point at +3 on the y axis.

To find the x- intercept, substitute 0 for y, and solve for x

x + 0 = 3  Again, subtracting 0, x = 3

So plot a point on the x-axis at +3

Use the line tool to connect the two points.

PLEASE HELP AND SHOW WORK i'm very confused
noname [10]

Answer:

a. about 15.51 miles, rounded to 15.5 miles

b. about 31.02 miles, rounded to 31 miles

Step-by-step explanation:

Sunday Monday Tuesday Wednesday Thursday Friday Saturday

 10           20           40          80             160       320        640

 1280      2560        5120      10240       20480   40960    81920

81920/5280 = 15.51515151, rounded to the nearest tenth of a mile, 15.5 miles

Question b asks for how many miles in total has he ran. That means we have to add each of the values shown above and that equals to 163830 feet.

Divide that by 5280 and that equals 31.02 miles, rounded to the nearest tenth, 31 miles.

Write each polynomial in standard form. Then give the leading coefficient. You may need to combine like terms before writing the
Bond [772]

Step-by-step explanation:

To write a polynomial in standard form, put the degree that are the greatest first

So here it would be

{x}^{5}   + 4 {x}^{3}  - 3 {x}^{2}  + 10

Remember constant are numbers that you learned back in elementary,

Numbers like 10,90,4,1,0,-3 etc.

Remember that constant are basically represented like this

k \times  {x}^{0}

For example, 10 is represented like

10 \times  {x}^{0}

Since 0 is the smallest degree possible, for a polynomial, constants are the last term of a polynomial in standard form

An electrical engineer wishes to compare the mean lifetimes of two types of transistors in an application involving high-tempera
Olin [163]

Answer:

(115.2642, 222.7358).

Step-by-step explanation:

Given data:

type A: n_1=60, xbar_1=1827, s_1=168

type B: n_2=180, xbar_2=1658, s_2=225

n_1 = sample size 1, n_2= sample size 2

xbar_1, xbar_2 are mean life of sample 1 and 2 respectively. Similarly, s_1 and s_2 are standard deviation of 1,2.

a=0.05, |Z(0.025)|=1.96 (from the  standard normal table)

So 95% CI is

(xbar_1 -xbar_2) ± Z×√[s1^2/n1 + s2^2/n2]

=(1827-1658) ± 1.96×sqrt(168^2/60 + 225^2/180)

= (115.2642, 222.7358).
