Answer:

Congruent figures.

Step-by-step explanation:

When the measure of angles and sides of two geometric figures is exactly the same, these figures are known as congruent figures.

Do not confuse the term congruent with similar. Similar figures are those which have the same measure of angles, but the side lengths are not same. However, the ratio of corresponding side lengths of two similar figures is the same. But in congruent figures measure of angles and measure of corresponding sides is always the same.

Find the -scores that bound the middle 96 of the area under the standard normal curve by using the TI-84 calculator.

Korvikt [17]

Answer:

$\alpha=1-0.96 =0.04$

And $\alpha/2= 0.02$ and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

$z_{\alpha/2}= \pm 2.054$

Step-by-step explanation:

For this case we want to find the limits with the middle 96% of the area below the normal curve, then the significance level would be:

$\alpha=1-0.96 =0.04$

And $\alpha/2= 0.02$ and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

$z_{\alpha/2}= \pm 2.054$

jonny [76]

Answer: f(x) = 1,024(0.50)^x

Step-by-step explanation:

Hi, to answer this question we have to apply a decreasing rate formula:

f(x)= P (1 - r) ^x

Where:

p = original number of players

r = decreasing rate (decimal form, since half of the players are eliminated the percent decrease is 50%)

x = rounds

f(x) = number of players after x rounds

Replacing with the values given:

f(x) = 1,024(1-50/100)^x

f(x) = 1,024(1-0.5)^x

f(x) = 1,024(0.5)^x

Given that g(x)=x+3 calculate g(-5)

hjlf

Note that -5 = x, plug in -5 for x

g(x) = x + 3

g(-5) = (-5) + 3

Simplify

g(-5) = -5 + 3

g(-5) = -2

g(-5) = -2 is your answer

Suppose you invest $750.00 in a fund earning 6% simple discount. A certain time later you withdraw the investment (principal and

barxatty [35]

Answer:

4.08 + 2 = 6.08 years

Step-by-step explanation:

we know that

Simple Interest(S.I.) = (P × R × T) ÷ 100

where, P = Principal = 750

R = Rate = 6%

T = unknown

⇒ S.I. = (750 × 6 × t)÷ 100

⇒ S.I. = 45t

Also, Amount = S.I + Principal

⇒ Amount = 750 + 45t

Now Formula for Compound Interest is:

$A = P(1+\frac{r}{100})^{t}$

where A = Amount

=1000

P = Principle

r = rate

t = total number of year

Here, P = 750 + 45t, r = 3.5% , and t = 2.

Putting all these values in above formula:

$1000 = (750 + 45t)(1+\frac{3.5}{100})^{2}$

⇒ $1000 = (750 + 45t)(1.071)$

⇒ t = 4.08

Hence, total time required will be 2 + 4.08 = 6.08 years.
