Answer:The answer to this question would be OPTION B.In a conjunction, / is true when both / and / are TRUE; otherwise, / is FALSE.

A conjunction refers to a compound statement, developed by combining two statement often through the use of the word 'AND'.  For example, the two statements, 'Roses are Red' (statement p) .... 'Violets are Blue' (statement q), can be combined to form a conjunction that reads 'Roses are Red and Violets are Blue.'  When it comes to conjunctions, it is or equivalent to the intersection of the two sets of statements (p and q → p ∩ q) which therefore means that in order for the conjunction to be true, both statements must be true, otherwise, the conjunction is false.

Attached below is a truth table that seeks to further explain the point (note: ^ represent the conjunction).

Ron has 75 blue marbles and 125 red marbles. Enter the percent of blue marbles as a part of all marbles.
Ann [662]

Answer:

Step-by-step explanation:

% = Red / (Blue + red ) * 100

% = 75/(125 + 75) * 100

% = 75 / 200 * 100

% = 7500 / 200 = 37.5% are blue

Jovita bought 3 1/3 cubic yards of mulch for the garden. She will need 2.5 cubic yards for the flowerbeds. How much mulch is lef
salantis [7]

1/3  =  0.333... (repeating)

-- Jovita bought  3.333 cubic yards.

-- She needs  2.5 cubic yards for the flowers.

-- The rest will be left for the veggies.
    If she doesn't spill any, that will be

                 (3.333)  minus (2.5)  =  0.833... (repeating) cubic yards.

Which point is an x-intercept of the quadratic equation (x-8)(x+9)
defon

Solve for x in each set of parentheses by setting them to 0:

X -8 = 0

X = 8

X+9 = 0

X =-9

You have two x intercepts (8,0) and (-9,0)

You didn’t list any choices to pick from but it would be either if the ones above.

Determine the value of k for which -3x^2+12x+k=0 has no real roots. ​
Crazy boy [7]

Answer:

K<-12

Step-by-step explanation:

+ For that, we need the delta negatif.

+ The delta= b^2-4ac=12^2-4(-3)(k)=144+12k<0

Then, 12k<-144 (divise both sides by 12)

we have k<-12

Or an other way:

-3x^2+12x+k=0  (divise both sides by -3)

x^2-4x-k/3=0

x^2-4x+4 -4-k/3=0

(x-2)^2=4+k/3

Now , we need 4+k/3<0, k/3<-4 or k<-12

Hope you understand.
