The owner of a music store received a shipment of stereos at a cost of $160 each. What will the selling price be if he applies a

kumpel [21]

The selling price will be $232 if he applies a 45% markup.

Step-by-step explanation:

Cost of each stereo = $160

Mark up = 45%

Amount of mark up = $\frac{45}{100}*160$

Amount of mark up = $\frac{7200}{100} = \$72$

Selling price = Cost of stereo + mark up

Selling price = 160 + 72 = $232

The selling price will be $232 if he applies a 45% markup.

5 = 2x + 5<br><br>what is this for Pre-Algebra

Talja [164]

Answer: p

Step-by-step explanation:

We want to start by isolating the variable.

Subtract 5 from both sides.

In this case, that will leave you with 0= 2x.

After this, you want to completely isolate the variable by dividing by two.

0/2 still equals 0, so X will equal 0.

Dada una distribución t de Student con 15 grados de libertad, calcule el valor de t1 tal que a) el área a la derecha de t1 sea 0

nikitadnepr [17]

Answer:

a) t₁ = 2,947

b) t₁ = 2,131

c) t₁ = 1,753

d) t₁ = 2,947 -t₁ = -2,947

e) t₁ = 2,131 -t₁ = -2, 131

Step-by-step explanation:

a) t₁ para el área a la derecha de 0,01

En la tabla t- student el t correspondiente a 0,01 es:

t₁ = 2,947

b) t₁ para el área a la izquierda sea de 0,95. Es igual al t para el cual el área de la drecha es 0,05

t₁ = 2,131

c) t₁ para que el área de la derecha sea 0,10

t₁ = 1,753

d) Buscar t₁ para el cual las áreas de derecha de (t₁) más la de la izquierda de (- t₁ ) sea 0,01.

Si el área es de 0,01 quere decir que la mitad, es decir 0,005 es el área para una cola, luego

t₁ = 2,947 y -t₁ = -2,947

e) Para que el área entre - t₁ y t₁ sea 0,95

t₁ = 2,131 y -t₁ = -2, 131
