Answer:

$Acceleration = 33.96ms^{-2}$

Step-by-step explanation:

Given

$Mass = 53kg$

$Force = 1800N$

Required

Determine the acceleration

The relationship between force, mass and acceleration is:

$Force = Mass * Acceleration$

Substitute values for Force and Mass

$1800 = 53 * Acceleration$

Solve for Acceleration

$Acceleration = 1800/53$

$Acceleration = 33.9622641509$

$Acceleration = 33.96ms^{-2}$ ---- Approximated

Find the equation of the line through (-4,-1) and parallel to y = -1/2x +1 in slope-

Alex17521 [72]

Step-by-step explanation:

Let the equation of the line be y = mx + c

since the line is parallel to y = -1/2x + 1, the two lines have the same gradient.

therefore, m = -1/2

sub (-4, -1):

-1 = -1/2(-4) + c

c = -3

therefore equation of the line is y = -1/2x - 3

This question demands knowledge on coordinate geometry's slope intercept form and finding unknowns. If you would like to venture further, you can check out my Instagram page (learntionary). Thanks!

If (x – 4) + 6 = 2 - (4 - 2x), then x = A. -4 B. -2 C. 2 D. 4

blondinia [14]

Answer:

x=4

Step-by-step explanation:

Remove the parentheses and turn the 4-2x and make it into 4+2x candle the equal term -4 and should be left with x+6=2+2x then move the variable to the left and change the sign so it would be x-2x=2-6 and collect like terms so it would be -x=2-6 and then calculate that and get -x= -4

(sorry its alot)

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tail

olganol [36]

Answer:

Two tailed test

Parameter tested= population standard deviation

Step-by-step explanation:

1) Important concepts

The chi-square test if the standard deviation of a population is equal to a given value. We can conduct the test two-side or a one-side.

For the case of two-side we want to check if the population deviation is equal to some value or no. And for the case of one-side we want to check if the population devition is higher or lower than a given value.

The system of hypothesis are:

$\sigma=\sigma_o$ Null hypothesis

$\sigma \neq \sigma_o$ Alternative hypothesis

That's when we use the two sided version but we can have other's alternative hypothesis if we use one-side test:

$\sigma < \sigma_o$ Alternative hypothesis

$\sigma > \sigma_o$ Alternative hypothesis

The test statistic to check the hypothesis is:

$t=(N-1)(\frac{s}{\sigma_o})^2$

For this special case the value of $\sigma_o =99$

Where N represent the sample size and s is the sample standard deviation. The ratio $\frac{s}{\sigma_o}$ is important since allows to compare the ratio of the sample standard deviation to the specified value. If this ratio is different from 1, we will have evidence that we can reject the null hypothesis.
