4 0

Answer:

Step-by-step explanation:

Slope= y2-y1/x2-x1

(1,5) is placed as (x1,y1) and (-1,-3) is placed as (x2,y2)

Plug it in

-3-5/-1-1

Simplify

-8/-2 = 4

Slope=4

Ms. drake invests $1000 at a simple interest rate of 8.5% for 2 years. how much interest will she earn in this time?

PilotLPTM [1.2K]

Ms. Drake will earn $\$ 170$ in this time from the investment of $\$ 1000$ at a simple interest with rate of interest $8.5\%$

<h3>What is the definition of simple interest?</h3>

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Conversely, for compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.

Formula for finding simple interest is $\frac{principal \times rate \ of \ interest \times time}{100}$

Given principal of Ms. Drake is $\$1000$

Rate of interest is $8.5 \%$

Time is $2$ years.

Interest $=\frac{1000 \times 8.5 \times 2}{100}$

$=\frac{17000}{100}\\=170$

Therefore, Ms. Drake will earn $\$ 170$ in this time.

Consider testing Upper H 0 : mu equals 20H0: μ=20 against Upper H Subscript a Baseline : mu less than 20Ha: μ<20 where muμ is

kolezko [41]

Answer:

Test: $\mu$ < 20 with normal distⁿ

Hypothesis test:

H0: $\mu \ge$ 20 (Null Hypothesis, H₀ : $\mu$ = 20 is also correct)

H1: $\mu$ < 20 (Alternative Hypothesis, also called H₁)

This is lower tailed test.

Since sample is large, sample standard deviation can be taken as an approximation of population standard deviation.

x = 19.3

$\sigma$ = 11.1

n = 444

significance level, $\alpha$ = 0.05 (If no value is given, we take level of 0.05)

Test statistic $z* = \frac{x-\mu}{\sigma/\sqrt{n}}$

$= \frac{19.3-20}{11.1/\sqrt{444}}$

= - 1.33

The presence of an angle bisector will result in what type of angles?

LenaWriter [7]

Answer:

Congruent angles

Step-by-step explanation:

Angle bisectors, divides the given angle into two equal parts

thus if value of angle is x then angle bisector will divide this angle into parts

of equal value x/2 .

_______________________

complementary angles are two angles whose sum is 90 degrees.

since we do not the value of angle we cannot say with certainty that the angles are complementary

Congruent angles are angles who have the same angular measurement.

since, in above problem we have seen that angle bisector divides the angle in two equal parts.

hence angles are equal and thus they are congruent angle.

Congruent angles is the correct answer.

_______________________________________

vertical angles are angle opposite two one another when two line cross each other.

Since in the problem line is not intersecting each other thus, angles do not qualify to be vertical angles

Supplementary angles are two angles whose sum is 180 degrees.

since we do not the value of angle we cannot say with certainty that the angles are Supplementary.

Hence correct option is Congruent angles
