Select the lesser of the two given number -11, -3

1 answer:

Grace [21]3 years ago

4 0

Answer: -11

Explanation: Once the number scale descends into the negatives, the numbers closest to zero are the biggest while those farther along the line are smaller. This is because it is negative, but if both numbers were positive, the answer would be three because it is of lesser value than positive 11. But in this case, it’s the opposite.

What is the solution of square root of x plus twelve equals x

Bess [88]

Answer:

x=4

Step-by-step explanation:

√x+12=x

x+12=x2(Square both sides)

x+12=x2

x+12−x2=x2−x2(Subtract x^2 from both sides)

−x2+x+12=0

(−x−3)(x−4)=0(Factor left side of equation)

−x−3=0 or x−4=0(Set factors equal to 0)

x=−3 or x=4

x=−3(Doesn't work in original equation)

x=√x+12

Write an equation that represents the line passing through the point -3, -1 with a slope of 4

Alex17521 [72]

Answer:

Equation that represents the line passing through the point -3, -1 with a slope of 4 is

$y= 4x+11$

Step-by-step explanation:

Equation of line in point slope form is

$y-y_1=m(x-x_1)$ -------(1)

Here

$m=4 \ \ \ and \ \ \ (x_1, y_1) = (-3, -1)$

Substituting values in equation (1)

$y+1=4(x+3)\\ y= 4x+11$

Random sample size of 81 are taken from an infinite population whose mean and standard deviation are 200 and 18, respectively. T

Ugo [173]

Answer:

the mean and standard error of the mean are 200 and 2 respectively.

Step-by-step explanation:

Given that ;

the sample size n = 81

population mean μ = 200

standard deviation of the infinite population σ = 18

A population is the whole set of values, or individuals you are interested in, from an experimental study.

The value of population characteristics such as the Population mean (μ), standard deviation (σ) are said to be known as the population distribution.

From the given information above;

The sample size is large and hence based on the central limit theorem the mean of all the means is same as the population mean 200.

i.e

$\mu = \bar \mu_x$ = 200

∴ The mean = 200

and the standard error of the mean can be determined via the relation:

$\mathbf{standard \ error \ of \ mean = \dfrac{\sigma}{\sqrt {n}}}$

$\mathbf{standard \ error \ of \ mean = \dfrac{18}{\sqrt {81}}}$

$\mathbf{standard \ error \ of \ mean = \dfrac{18}{9}}$

$\mathbf{standard \ error \ of \ mean =2}$

Therefore ; the mean and standard error of the mean are 200 and 2 respectively.
