Answer:

$g(x) - f(x) = x^{2} - 2x - 4$

Step-by-step explanation:

g(x) - f(x) = $(x^{2} + 1) - (2x + 5)$

<em><u>Multiply the -1 in then add the two expressions together.</u></em>

$(x^{2} + 1) + (-2x - 5) = x^{2} - 2x - 4$

On a factory floor, 30 out of every 140 toy robots is defective. What percent is defective?

yaroslaw [1]

Answer:

$21.43\%$

Step-by-step explanation:

we know that

To find out the percent of robots which are defective, divided the number of defective robots by the total number of robots and multiply the result by 100

Let

x ----> the number of defective robots

y ----> the total number of robots

p ---> percentage of robots which are defective

$p=\frac{x}{y} (100)$

we have

$x=30\\y=140$

substitute

$p=\frac{30}{140}(100)$

$p=21.43\%$

URGENT EXPLANATION AND SOLVING

Alex787 [66]

$\cfrac{a}{\sin(a)} = \cfrac{b}{\sin(b)} 
$

$\cfrac{31}{\sin(42)} = \cfrac{37}{\sin(x)} 
$

$31\sin(x) = 37 \sin(42)$

$\sin(x) = \cfrac{37 \sin(42) }{31}$

$x = \sin^{-1}(\cfrac{37 \sin(42) }{31} )$

$x = 53 \textdegree$

Answer: 53°

A random sample of 10 single mothers was drawn from a Obstetrics Clinic. Their ages are 22, 17, 27, 20, 23, 19, 24, 18, 19, and

Sever21 [200]

Answer:

The two-tailed P value equals 0.2308

By conventional criteria, this difference is considered to be not statistically significant.

Step-by-step explanation:

Given is a random sample of 10 single mothers

the ages are given as

22, 17, 27, 20, 23, 19, 24, 18, 19, and 24 years

H0: Mean = 20

Ha: Mean not equals 20

(two tailed test at 5% significance level)

The hypothetical mean is 20.00

The actual mean is 21.30

The difference between these two values is 1.30

The 95% confidence interval of this difference:

From -0.99 to 3.59

t = 1.2851

df = 9

standard error = 1.012

The two-tailed P value equals 0.2308

By conventional criteria, this difference is considered to be not statistically significant.
