Solve (z + 6)2 = 5

{−6±5‾√}

{6±5‾√}

{5‾√±−6}

{−6+5‾√,6−5‾√}

9514 1404 393

**Answer:**

(a) -6±√5

**Step-by-step explanation:**

(z +6)^2 = 5 . . . . . given

z +6 = ±√5 . . . . . take the square root

** z = -6 ±√5** . . . . . . subtract 6

A random sample of 146 recent donations at a certain blood bank reveals that 81 were type A blood. Does this suggest that the actual percentage of type A donations differs from 40%, the percentage of the population having type A blood

**Answer:**

We reject H₀ the actual percentage of type A donations differs from 40%

**Step-by-step explanation:**

**Sample information:**

**sample size n = 146**

**Type A x₁ = 81 and p₁ = 81 / 146 p₁ = 0,5547**

**then q₁ = 1 - p₁ q₁ = 1 - 0,5547 q₁ = 0,4453**

**We choose as significance level α = 5% α = 0,05 α /2 = 0,025**

**from z-table we find z (c) = 1,96**

**National % of the population ( μ = 40 % μ = 0,4 )**

**Test hypothesis**

**Null hypothesis H₀ p₁ = μ**

**Alternative Hypothesis Hₐ p₁ ≠ μ**

**The Alternative hypothesis indicates that the test is a two-tail test**

**z(s) = ( p₁ - μ )/ √ p₁*q₁ / n**

**z(s) = ( 0,5547 - 0,40 )/ √ 0,5547*0,4453 / 146**

**z(s) = 0,1547 / 0,041**

**z(s) = 3,77**

**Comparing z(s) and z(c)**

**z(s) > z(c) **

**z(s) is in the rejection region. We reject H₀. Sample does not give evidence to support that the actual percentage of type A donations is equal to the national population**

Janae solved the equation 3.67 = c − 2.13 , and found the value for c. Janae's solution was c =1.54 Do you agree or disagree with her solution. Explain. Show your work. plzzz help me ill give yo a brainlyiest

**Answer:**

Solution;

given equation : 3.67 = c - 2.13

On solving equation, we get

c = 3.67 +2.13

c = 5.8

Hence, Janae solution is incorrect. So I disagree.

Answer: No because the answer is c =5.8 or 5.80

Step-by-step explanation:

Add 2.13 to both sides. 3.67 + 2.13 = 5.80

Joseph and Molly each have coin collections. Joseph starts with 15 coins in his collection and adds 25 coins each month. Molly starts with 25 coins in her collection and adds 25 coins each month. How many coins would Joseph have after 3 months?

**Answer:**

Joseph has 90 coins after 3 months

**Step-by-step explanation:**

Joseph: 25x + 15

Molly: 25x + 25

x = 3

Joseph: 25(3) + 15 = 90

Find the third quartile Q3 of the list of 24 sorted values shown below.

30 31 31 37 38 38 39 39 42 42 43 46 47 48 50 52 54 57 61 63 68 69 76 79

The third quartile Q3 is

(Type an integer or a decimal.)

**Answer:**

** 60**

**Step-by-step explanation:**

The computation of the third quartile is given below:

The third quartile Q3 is

**= 3(n + 1)÷ 4**

= 3 (24 + 1) ÷ 4

= 75 ÷ 4

= 18.75th term

Now the 18.75th term is

= 18th term + 0.75 term

= 57 + (19 term - 18term)

= 57 + 0.75 (61 - 57)

= 57 + 0.75 (4)

=** 60**

Solve for x.

Enter the solutions from least to greatest.

(2x + 4)(3x − 2) = 0

lesser x =

greater x =

**Answer:**

lesser x = -2, greater x = 2/3

**Step-by-step explanation:**

(2x+4)= 0 ---> bring 4 to the other side

2x=-4 ----> divide by 2 on both sides

x= -4/2 = -2 ----> simplify

(3x-2)= 0 ----> bring the 2 to the other side

3x=2 ----> divide by three on both sides

x=2/3

In APQR, PR is extended through point R to point S,

m_QRS = (4x – 15)°, m_RPQ = (x + 1), and

mZPQR = (x - 2)°. Find mZRPQ.

**Answer:**

m∠RPQ = 8°

**Step-by-step explanation:**

m∠QRS = 4x - 15

m∠RPQ = x + 1

m∠PQR = x - 2

m∠QRS is exterior angle and m∠RPQ and m∠PQr are opposite interior angles to m∠QRS

m∠QRS = m∠RPQ + m∠PQR **{Exterior angle property of triangle}**

4x - 15 = x +1 + x - 2

4x - 15 = x + x + 1-2 **{Combine like terms}**

4x - 15 = 2x - 1 **{Subtract 2x from both sides}**

4x - 2x - 15 = - 1

2x - 15 = - 1 {**Add 15 to both sides**}

2x = -1 + 15

2x = 14 {**Divide both sides by 2**}

x = 14/2

**Answer:**

13u√2u

**Step-by-step explanation:**

Remark

Removing factors from under the square root sign means factoring the numbers into prime factors. If there are an even number of equal prime factors, take one out and throw one away for all the primes that are the same. An odd number of factors always leaves 1 under the root sign.

For example

u^3 = u * u * u

One of the u's will be left behind. Of the two others, one will be discarded and one will be taken outside the root sign.

√u^3 = √(u * u * u) = u√u

one u taken out. 1 u left behind 1 u discarded.**Question Breakdown**

**Answer**

Let {u1,u2,u3} be an orthonormal basis for an inner product space V. If

v=au1+bu2+cu3

is so that ∥v∥=42, v is orthogonal to u3, and ⟨v,u2⟩=−42, find the possible values for a, b, and c.

• ||* v*|| = 42, which is to say

||* v*||² = 〈

… = 〈*a* * u*₁ +

… = *a* ² 〈* u*₁,

… = *a* ² ||* u*₁||² +

[since each vector in the basis for *V* is orthogonal to any other vector in the basis, and 〈* x*,

42² = *a* ² + *b* ² + *c* ²

[since each vector in the basis has unit length]

42 = √(*a* ² + *b* ² + *c* ²)

• ** v** is orthogonal to

〈* v*,

… = *a* 〈* u*₁,

… = *c* ||* u*₃||²

… = *c*

which gives *c* = 0, and so

42 = √(*a* ² + *b* ²)

• Lastly, 〈* v*,

〈* v*,

… = *a* 〈* u*₁,

… = *b *||* u*₂||²

… = *b*

so that *b* = -42. Then

42 = √(*a* ² + (-42)²) → *a* = 0

So we have **a**** = 0, ****b**** = -42, and ****c**** = 0**.

**The required values are, **[tex]a=0,b=-42 ,c=0[/tex]

**Given,**

[tex]v=au_1+bu_2+cu_3[/tex]

[tex]\left\| V\right\|=42[/tex]

**Computation:**

Since, [tex]v[/tex] is orthogonal to [tex]u_3[/tex] then we have,

[tex]\left<v,u_3 \right> =0\\\left< v,u_2\right> =-42[/tex]

Then,

[tex]\left\| V\right\|^2=\left<v,v \right>\\=\left<au_1+bu_2+cu_3,au_1+bu_2+cu_3 \right>\\=a_2\left\|u_1 \right\|^2+b_2\left\|u_2 \right\|^2+c_2\left\|u_3 \right\|^2\\=a^2+b^2+c^2\\=a^2+b^2+c^2=42^2[/tex]

As we know,

[tex]a=\left<v_1u_1 \right>\\b=\left< v_1u_2\right>= -42\\c=\left<v_1u_3 \right> =0[/tex]

[tex]a_2+b_2+c_2=42\\a=0[/tex]
