A certain solution contains 4.3 grams of salt per liter.
IRISSAK [1]

Answer:

47.3 grams

Step-by-step explanation:

Given: A solution contains 4.3 grams of salt per liter.

To find: Amount of salt in 11 liters of the solution

Solution:

Amount of salt in 1 liter of the solution = 4.3 grams

So, amount of salt in 11 liters of the solution = 11 × Amount of salt in 1 liter of the solution = 11 × 4.3 = 47.3 grams

Hence, 11 liters of the solution contains 47.3 grams of salt.

Find the Slope. (4, 4) (2, 3)<br> please and thanks
Dmitriy789 [7]

Answer: its m= 1/2

Step-by-step explanation:$\mathrm{Slope\:between\:two\:points}:\quad\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$Slope between two points:    Slope=

y2−y1

x2−x1

$\left(x_1,\:y_1\right)=\left(2,\:3\right),\:\left(x_2,\:y_2\right)=\left(4,\:4\right)$(x1, y1)=(2, 3), (x2, y2)=(4, 4)

$m=\frac{4-3}{4-2}$m=

4−3

4−2

$\mathrm{Refine}$Refine

$m=\frac{1}{2}$m=

Examples

$slope\:3x+3y-6=0$slope 3x+3y−6=0

$slope\:f\left(x\right)=2x-1$slope f(x)=2x−1

$slope\:\left(-1,\:1\right),\:\left(-2,\:-3\right)$slope (−1, 1), (−2, −3)

$slope\:\left(-1,\:-2\right),\:\left(1,\:2\right)$slope (−1, −2), (1, 2)

$slope\:\left(0,\:-4\right),\:\left(-1,\:-7\right)$slope (0, −4), (−1, −7)

$slope\:\left(-4,\:2\right),\:\left(0,\:3\right)$slope (−4, 2), (0, 3)

Of all of the individuals who develop a certain rash, suppose the mean recovery time for individuals who do not use any form of
VashaNatasha [74]

Answer:

z(s) is in the rejection  region. We reject  H₀. We dont have enought evidence to support that the cream has effect over the recovery time

Step-by-step explanation:

Sample information:

Size     n = 100

mean   x = 28,5

Population information

μ₀  =  30

Standard deviation  σ   = 8

Test Hypothesis

Null Hypothesis          H₀                x =  μ₀

Alternative Hypothesis   Hₐ           x <  μ₀

We assume CI = 95 %   then α = 5 %    α = 0,05

As the alternative hypothesis suggest we should develop a one tail-test on the left ( we need to find out if the cream have any effect on the rash), effects on the rash could be measured as days of recovery

A z(c) for 0,05 from z-table is:  z(c) = - 1,64

z(s) = ( x - μ₀ ) / σ/√n

z(s) = ( 28,5 - 30 ) / 8/√100

z(s) = - 1,5 * 10 / 8

z(s) =  - 1,875

Comparing z(s)  and z(c)

|z(s)| < |z(c)|        1,875  > 1,64

z(s) is in the rejection  region. We reject  H₀. We dont have enought evidence to support that the cream has effect over the recovery time
