Answer:

∠Q  = 53.13 degrees

Step-by-step explanation:

Given that ∆PQR, ∠P = 90degrees , this means that the triangle is a right angled triangle

Hence using the notation

SOH CAH TOA

where S is sine, C is cosine, T is tangent and O, A and H represents the size of the opposite, adjacent and hypotenuse sides

Considering  ∠Q and the given sides

PR=16cm is the opposite side,

PQ= 12 cm is the adjacent side hence we use TOA

Tan Q = 16/12 =

Q = Arc tan 16/12

= 53.13 degrees

Answer:permutations

Step-by-step explanation:

Answer:

Part A is 5/6 of the whole

Part B is 1/6 of the whole

Solution:

Assuming there are no other parts,

the Whole = A + B is the denominator:

Whole = 15 + 3 = 18

Part A = 15 and Part B = 3 are numerators for each fraction.

The fractions are then:

15/18 and 3/18

Meaning:

Part A is 15/18 of the whole

Part B is 3/18 of the whole

Reducing the fractions, it is also true that:

Part A = 5/6 of the whole

Part B = 1/6 of the whole

Answer:

Step-by-step explanation:

Answer:

look at the horizontal line in the picture. the degree measure of any line is 180° given there's a perpendicular ray through that horizontal line it's therfore split into two sides both with angle measure of 90°.

given f is 71° then g can be found knowing that both g and f must add to 90°. 71+g=90. g=19°

now look at f again. f and d are what's known as vertical angles and that means that they're angle measures are congruent. therfore the measure of d is 71° d=71°

Finally to find e we notice that angle d and e form a straight line which means both angles measures must add to 180°. therefore e can be found by computing d+e=180

aunaitituitmg our information we know 71+e=180 then e must equal 109° e=109°

Step-by-step explanation:

Just do $123 million - $3 million

Answer:

A) -1

Step-by-step explanation:

anything raised to the zero power is 1 but if there is a negative without parentheses around it then it becomes -1

ex, (-4)° = 1

Answer:

It would be -1.

Step-by-step explanation:

This is because any postive number to the power of 0 equals 1 but since there is a negative sign, it would become -1.

Answer:

a) [tex]-225.000\,G[/tex], b) La cantidad de meses en los que el saldo fue inferior al permitido se calcula al dividir el descuento total por la multa mensual, c) El saldo fue menor durante 3 meses.

Step-by-step explanation:

a) Asumamos que la caja de ahorro es un recipiente, donde las entradas de dinero son positivas y las salidas negativas. Un descuento debe entenderse como negativa en tanto que se paga en función de no superar el saldo mínimo permitido en un período determinado. En consecuencia, el descuento sufrido por el padre de Leticia se describe como -225.000 G.

b) y c) La cantidad de meses en los que el saldo fue inferior al permitido se calcula al dividir el descuento total por la multa mensual, es decir:

[tex]x = \frac{225.000\,G}{75.000\,\frac{G}{mes} }[/tex]

[tex]x = 3\,meses[/tex]

Answer:

g = 55

f = 55

h = 55

Step-by-step explanation:

g = 180 - 25 = 55

this is because angle on a straight line is equal to 180 degrees

f = 55

alternate angles are equal. f alternates g

h = 55

opposite angels are equal

Answer:30 boys

Step-by-step explanation: There are 120 students, three-fourths are girls. Nine out of twelve is equal to three fourths, if you add a zero to the end of twelve and nine you get 90 out of 120, which is how many girls there are. If you subtract 90 from 120 you get 30 or one-fourth. The number of boys is equal to one-fourth because there is only one-foutlrth left. So, there are 30 boys.

Answer:

We accept H₀    p₁  =  p₂  : We don´t have evidence to support any difference between the proportions

Step-by-step explanation:

Information from Ivan Allen College;

Sample size  n₁  = 137

The proportion of students failing

p₁  =  0,283      q₁ =  1  -  p₁     q₁  =  1  -  0,283    q₁ =  0,717

Information from College of Computing:

Sample size   n₂  =  111

x₂  ( number of students failing )  =  22

The proportion of students failing

p₂  =  0,1981      q₂  =  1  -  0,1981     q₂  =  0,8019

Hypothesis Test:

Null Hypothesis:                             H₀          p₁  =  p₂

Alternative Hypothesis                  Hₐ          p₁  ≠  p₂

Alternative Hypothesis indicates the test is a two-tail test

Choosing a significance level   α  =  0,05   ( Confidence Interval 95%)

we get from z table   z(c)  = 1,64

To obtain z(s)

z(s)  =  (  p₁ -  p₂  ) / EED

EED = √(p₁*q₁)/n₁  +  p₂*q₂)/n₂

EED = √ (0,283*0,717)/137   +  ( 0,1981*0,8019)/111

EED = √  0,00148  +  0,00143

EED = 0,054

And

z(s)  = ( 0,283 -  0,1981 )/ 0,054

z(s) = 1,57

Comparing   z(c)  and  z(s)

z(c) > z(s)

Then z(s) is in the acceptance region for H₀ : We accept H₀
