Jamal worked over summer at his dads office. He earned $2200 total. He is planning on spending his money on a $50 per month gym

Tju [1.3M]

Answer: He will have $1974 in April.

Step-by-step explanation:

Given : Total money he earned = $2200

He spent $50 per month gym membership, a $68 monthly phone plan $48 monthly gas plan and $60 monthly fun plan.

So , Money he has left = Money he earned - Total expenditure

= $ ( 2200- (50+68+48+60))

= $ (2200- 226)

= $ 1974

Hence, He will have $1974 in April.

Let Q(x, y) be the predicate "If x < y then x2 < y2," with domain for both x and y being R, the set of all real numbers.

Levart [38]

Answer:

a) Q(-2,1) is false

b) Q(-5,2) is false

c)Q(3,8) is true

d)Q(9,10) is true

Step-by-step explanation:

Given data is $Q(x,y)$ is predicate that $x$ then $x^{2}$ . where $x,y$ are rational numbers.

a)

when $x=-2, y=1$

Here $-2$ that is $x$ satisfied. Then

$(-2)^{2}$

$4$ this is wrong. since $4>1$

That is $x^{2}$ $>y^{2}$ Thus $Q(x,y)$ $=Q(-2,1)$ is false.

b)

Assume $Q(x,y)=Q(-5,2)$ .

That is $x=-5, y=2$

Here $-5$ that is $x$ this condition is satisfied.

Then

$(-5)^{2}$

$25$ this is not true. since $25>4$ .

This is similar to the truth value of part (a).

Since in both $x$ satisfied and $x^{2} >y^{2}$ for both the points.

c)

if $Q(x,y)=Q(3,8)$ that is $x=3$ and $y=8$

Here $3$ this satisfies the condition $x$ .

Then $3^{2}$

$9$ This also satisfies the condition $x^{2}$ .

Hence $Q(3,8)$ exists and it is true.

d)

Assume $Q(x,y)=Q(9,10)$

Here $9$ satisfies the condition $x$

Then $9^{2}$

$81$ satisfies the condition $x^{2}$ .

Thus, $Q(9,10)$ point exists and it is true. This satisfies the same values as in part (c)

)if there are 8 parts in a product and they are each at 6 sigma with a 1.5 shift, determine the ppm for the product

Maru [420]

Answer:

ppm value = 0.000027 parts per million

Step-by-step explanation:

Given:

number of parts(n) = 8

From table: percent conformance in six sigma = 0.9999966

Using the formula of ppm value in terms of percent conformance and number of parts:

$ppm\,value = ( 1 -( \frac{percent\,conformance}{100} )^n )$

Plugging in the values:

$ppm\,value = (1 - (\frac{0.9999966}{100} )^8 )$

$ppm\,value = ( 1- 0.999972)\\$

$ppm\,value = 0.000027\,parts\,per\,million$

Ted earned $4,300 from his summer internship that he plans to invest so that he can buy a used car after three years. Ted choose

olganol [36]

Answer: Yes he will be

Step-by-step explanation:

To find out if Ted can afford the car, find the future value of $4,300 in three years.

First convert the number of years and rates to quarterly values as this is the compounding period:

Term = 3 * 4 quarters = 12 quarters

Rate = 5.5% / 4 = 1.375% per quarter

Future value = Amount * ( 1 + rate) ^ term

= 4,300 * ( 1 + 1.375%)¹²

= $5,065.69

<em>Considering that Ted makes $5,065.69 in 3 years, he will be able to buy a car that costs $4,700.</em>
